Plotly Python Tutorial for Machine Learning Specialists

Plotly is an open-source Python graphing library that is great for building beautiful and interactive visualizations. It is an awesome tool for discovering patterns in a dataset before delving into machine learning modeling. In this article, we will look at how to use it in an example-driven way. 

Some of the visualizations you can expect to see include:

  • line plots, 
  • scatter plots, 
  • bar charts, 
  • error bars, 
  • box plots, 
  • histograms, 
  • heatmaps, 
  • subplots, 
  • and bubble charts.

📊The Best Tools for Machine Learning Model Visualization


Why you would choose Plotly

Now, the truth is that you can still get some of these visualizations using Matplotlib, Seaborn, or Bokeh. There are a couple of reasons why you would choose Plotly:

  • the visualizations are interactive unlike Seaborn and Matplotlib;
  • it’s quite straightforward to generate complicated visuals using Plotly’s high-level Express API;
  • Plotly also provides a framework known as Plotly Dash that you can use to host your visualizations as well as machine learning projects;
  • you can generate HTML code for your visualizations, if you like, you can embed this on your website.

That said, generating the visualizations will require that you have your dataset cleaned. That’s a crucial part, otherwise, you will have visuals that deliver the wrong information. In this article, we skip the cleaning and pre-processing part to focus on the visualizations. We’ll provide the entire notebook used at the end of the tutorial. 

It is important that you also keep in mind best practices when creating visualizations, for example:

  • using colors that are eye-friendly
  • ensure that the numbers add up, for example in a pie chart the percentages should total to 100%
  • use the right color scale so that it is automatically clear to the viewer which color represents the higher number and which one represents the lower
  • don’t put too much data in the same visual, for example, you can group and plot the topmost items instead of plotting everything in the dataset
  • ensure that the plot is not too busy
  • always add the source of your data, even when you are the one who has collected it. It builds credibility. 

We can interact with the Plotly API in two ways; 

In this piece, we’ll be using them interchangeably. 

Plotly histogram

A histogram is a representation of the distribution of numerical data with the data being grouped into bins. The count for each bin is then shown. In Plotly, the data can be aggregated using aggregation functions such as sum or average. In Plotly the data to be binned can also be categorical. Here’s an example:

import plotly.express as px fig = px.histogram(views, x="views") fig.show()
plotly histogram

Plotly bar chart

A Bar Plot is a great visualization when you want to display a categorical column and a numerical column. It shows the number of a certain numerical column in every category. Plotly Express makes it very easy to plot one. 

fig = px.bar(views_top, x='event', y='views') fig.show()
plotly bar chart

You are not just limited to vertical bar charts, you can also use a horizontal one. This is done by defining the `orientation`. 

fig = px.bar(views_top, x='views', y='event',orientation='h') fig.show()
plotly bar chart

Plotly pie chart

A pie chart is another visualization type for showing the number of items in every category. This type enables the user to quickly determine the share of a particular item or value on the whole dataset. Let’s show how one can be plotted using Plotly’s Graph Objects this time. 

import plotly.graph_objects as go fig = go.Figure( data=[ go.Pie(labels=labels, values=values) ]) fig.show()
plotly pie chart

Plotly donut chart

You can change the above visual to a donut chart by specifying the parameter. This is the size of the hole you would like to have for the donut chart. 

fig = go.Figure( data=[ go.Pie(labels=labels, values=values, hole=0.2) ]) fig.show()
plotly donut chart

Plotly scatter plot

Scatterplots are great for determining whether there is a relationship or correlation between two numerical variables.

fig = px.scatter(df,x='comments',y='views') fig.show()
plotly scatter plot

Plotly line chart

A line chart is majorly used to show how a certain numerical value changes over time or over a certain interval. 

fig = px.line(talks, x="published_year", y="number_of_events") fig.show()
plotly line chart

Plotly annotations

Adding text labels and annotations is quite straightforward in Plotly. In a scatter plot this can be done by specifying the parameter. 

fig = px.scatter(df,x='comments',y='views',color='duration',text="published_day") fig.show()
plotly annotations

Plotly 3D scatter

In Plotly, a 3D scatterplot can be created by passing the x, y, and z parameters.

fig = px.scatter_3d(df,x='comments',y='views',z='duration',color='views') fig.show()
plotly 3d scatter

Plotly Write to HTML

Plotly also allows you to save any of your visualizations to an HTML file. This is surprisingly easy to do. 

fig.write_html("3d.html")
plotly html

Plotly 3D surface

Let’s now look at how to plot a 3D surface in Plotly. Similar to the 3D scatter, we have to pass the x,y, and z parameters.

fig = go.Figure(data=[go.Surface(z=df[['duration','views','comments']].values)]) fig.update_layout(title='3D Surface', autosize=False, width=500, height=500, margin=dict(l=65, r=50, b=65, t=90)) fig.show()
plotly 3D Surface

Plotly bubble chart

A Plotly bubble chart is very similar to a scatterplot. In fact, it is built from the scatterplot. The only item we add to it is the size of the bubble. 

fig = px.scatter(df,x='comments',y='views',size='duration',color='num_speaker', log_x=True, size_max=60) fig.show()
plotly bubble chart

Plotly table

Plotly can also be used to visualize a data frame as a table. We can use Plotly Graph Objects to achieve this. We pass the header and the cells to the table. We can also specify the styling as shown below:

fig = go.Figure(data=[go.Table(header=dict(values=views_top.columns, fill_color='yellow', ), cells=dict(values=[views_top['event'],views_top['views']], fill_color='paleturquoise', )) ]) fig.show()
plotly table

Plotly heatmap

We can use a density heatmap to visualize the 2D distribution of an aggregate function. The aggregate function is applied on the variable in the z axis. The function can be the sum, average or even the count. 

fig = px.density_heatmap(df, x="published_year", y="views",z="comments") fig.show()
plotly heatmap

Plotly animations

Plotly Animations can be used to animate the changes in certain values over time. In order to achieve that, one has to define the . In this case, it’s the year.

px.scatter(df, x="duration", y="comments",animation_frame="published_year", size="duration", color="published_day")
plotly animations

Plotly box plot

A box plot shows the representation of data through their quartiles. Values falling outside the fourth quartile represent the outliers in your dataset.

fig = px.box(df, x="published_day", y="duration") fig.show()
plotly box plot

Plotly maps

In order to work with maps in Plotly, you will need to head over to Mapbox and grab your Mapbox API key. With the at hand, you can visualize your data on a map in Plotly. This is done using the while passing the latitude and the longitude. 

px.set_mapbox_access_token('YOURTOKEN') fig = px.scatter_mapbox(df, lat="lat", lon="lon", color="region", size="views", color_continuous_scale= px.colors.cyclical.IceFire, size_max=15) fig.show()
plotly maps

Plotly subplots

With Plotly, we can also visualize multiple plots on the same graph. This is done using Plotly Subplots. The plots are created by defining a . The graphs will be broken into as many unique values as available from the column. 

px.scatter(df, x="duration", y="comments", animation_frame="published_month", animation_group="event", facet_col="published_day",width=1500, height=500, size="views", color="published_day", )
plotly subplots

Plotly error bars

Error bars are used to show the variability of data in a visualization. Generally, they help in showing the estimated error or the preciseness of a certain measure. The length of the error bar reveals the level of uncertainty. Longer error bars indicate that the data points are more spread out hence more uncertain. They can be applied to graphs such as line charts, bar graphs, and scatterplots.

fig = go.Figure( data=[ go.Bar( x=views_top['event'], y=views_top['views'], error_y=dict(type='data', array=views_top['error'].values) ) ]) fig.show()
plotly error bars

Final thoughts

Hopefully, this piece has shown you how you can use Plotly in your next machine learning workflow. You can even use it to visualize the performance metrics of your machine learning models. Unlike other tools, its visuals are eye-catching as well as interactive. 

The interactivity enables you to zoom in and out of specific parts in the graph. In this way, you can look a little deeper to analyze your graph in more detail. Specifically, we have seen how you can use popular graphs such as histograms, bar charts, and scatter plots in Plotly. We have also seen that we can build multiple plots on the same graph as well as visualize data on the map. 

The Notebook used can be found here. 

Happy plotting – no pun intended!

The Best Tools for Machine Learning Model Visualization

4 mins read | Paweł Kijko | Posted May 25, 2020

The phrase “Every model is wrong but some are useful” is especially true in Machine Learning. When developing machine learning models you should always understand where it works as expected and where it fails miserably.

There are many methods that you can use to get that understanding:

  • Look at evaluation metrics (also you should know how to choose an evaluation metric for your problem)
  • Look at performance charts like ROC, Lift Curve, Confusion Matrix, and others
  • Look at learning curves to estimate overfitting
  • Look at model predictions on best/worst cases
  • Look how resource-intensive is model training and inference (they translate to serious costs and will be crucial to the business side of things) 

Once you get some decent understanding for one model you are good, right? Wrong 🙂

Typically, you need to do some or a lot of experimenting with model improvement ideas and visualizing differences between various experiments become crucial. 

You can do all of those (or most of those) yourself but today there are tools that you can use. If you’re looking for the best tools that will help you visualize, organize, and gather data, you’re in the right place.

Data Visualization with Plotly and Pandas

This example will show you how to leverage Plotly’s API for Python (and Pandas) to visualize data from a Socrata dataset. We’ll be using Plotly’s recently open sourced library and connecting it to a IPython/Pandas setup with cufflinks. Cufflinks patches Pandas so that you can visualize straight from a dataframe object(Very convenient!).

Let’s start by importing libraries…

We’ll be taking a look at NYPD’s Motor Vehicle Collisions dataset. The dataset contains 3 years of data (from 2012 to 2015) and gets constantly updated. It has very valuable information like the coordinates where the incident happened, the borough, amount of injured people and more. I’m only interested in last year’s data, so I’ll factor that into my query below using SoQL:

Now that we got our data, let’s list the columns and see what we have to work with:

Let’s look at the contributing factors of vehicle collisions. The factors are inconveniently divided into 5 columns, however pandas’ method should help us concatenate them into one:

Now let’s plot! Cufflinks conviniently connects plotly to the method in my dataframe. Let’s plot the occurence of each factor in a bar chart:

That’s a nice and fast way to visuzlie this data, but there is room for improvement: Plotly charts have two main components, and . These components are very customizable. Let’s recreate the bar chart in a horizontal orientation and with more space for the labels. Also, let’s get rid of the values.

Now let’s look at incidents over time. I’m gonna transform the date column into an actual date object so that plotly is able to graph it in a time series. In addition, we want to make sure that the df is sorted by date:

Now we can use the method to aggregate incidents by date as well as sum deaths per day. And again, plotting them is as easy as calling the method in our dataframe.

Finally, the previous charts can be merged into one, making good use of the and components:

And there you have it.

Overview

Update: June 2021

With the rise of Data Scientists, Financial coders, or Traders (aka Citizen Developers), data visualization is a big part of how to present data, information, and its context to the readers (Financial team, Marketing team, etc.). The good data analysis itself cannot be used with a good graph representation.

The Matplotlib Pyplot is a de-facto library for making interactive plots and data visualization in the Python and Data Scientists world. However, the Matplotlib is a huge library that contains several interfaces, capabilities, and 1000+ pages of documents.

There are a lot of other alternative Plotting libraries such as Seaborn (which is a high-level interface of Matplotlib), Spotify's Chartify, Bokeh, Plotly Python, etc.

This example project demonstrates how to use the Plotly Python library to plot various types of graphs. The demo application uses Corona Virus Disease (COVID-19), Environmental, Social and Governance, and Financial data from Eikon Data API as an example of a dataset.

Note: This article is focusing on the Plotly Python with classic Jupyter Notebook only. There are some minor differences for the Plotly Python with JupyterLab, please see the JupyterLab example in GitHub repository.

Introduction to Plotly Python

Plotly Python is a free and open-source interactive graphing library for Python. The library is built on top of plotly.js JavaScript library (GitHub). Both Plotly Python and Plotly JavaScript are part of Plotly's Dash and Chart Studio applications suites which provide interactively, scientific data visualization libraries/solutions for Data Scientists and Enterprise.

This article Notebook will focus on the Plotly Python open-source library versions 4.14.35.0.0, and 4.5.2 (4.5.2 for the CodeBook environment only).

The example code of Plotly Python is the following:

Plotly Example Chart

Introduction to Eikon Data API

The Eikon Data API (aka DAPI) provides access to certain Refinitiv Eikon/Refinitiv Workspace data with seamless workflow with the same data across all applications running on the desktop. The API allows developers to tap into the full breadth of community tools through a modern API with native Python support.

Eikon Data API Overview

If you are not familiar with Eikon Data API or Python, the following resources are highly recommended to read before you proceed with further steps.

Note:

  • This article is based on Eikon Data API versions 1.1.10 and 1.1.6.post3 (In the CodeBook application).
  • Pleases see Eikon Data API Usage and Limits Guideline regarding the API data coverage and data limit.

Prerequisite

This example requires the following dependencies software and libraries.

  1. Refinitiv Eikon or Refinitiv Workspace application with access to Eikon Data APIs.
  2. Python Anaconda or MiniConda distribution/package manager.
  3. Classic Jupyter Notebook or JupyterLab applications
  4. Internet connection.

Note:

  • This Project has been qualified with Python version 3.8.8 and Conda version 4.10.1

Please contact your Refinitiv's representative to help you to access Refinitiv Workspace/Eikon credentials. You can generate/manage the AppKey by follow the steps in Eikon Data API Quick Start page.

Code Walkthrough

Import Eikon Data API Libraries

The application needs to import Eikon and related libraries in order to interact with the Eikon Data API and Pandas.

Then we intialize the Eikon Data API session by passing the app key information to the set_app_key() function.

COVID-19 Data

Let's start with the COVID-19 data which is available in the Refinitiv Workspace/Refinitiv Eikon platform via the following instrument's pattern:

  • [Country Code]CCOV=ECI: Covid-19 Total Cases
  • [Country Code]NCOV=ECI: Covid-19 New Cases
  • [Country Code]ACOV=ECI: Covid-19 Active Cases
  • [Country Code]RCOV=ECI: Covid-19 Recovered Cases
  • [Country Code]DCOV=ECI: Covid-19 Death Cases

So, the example instruments of USA Covid-19 data are USCCOV=ECIUSNCOV=ECIUSACOV=ECIUSRCOV=ECI, and USDCOV=ECI instruments.

USA COVID-19 Instruments

You can find each country's COVID-19 data from Workspace/Eikon Economic Indicators ("ECONNID") application, and then choosing Country and Indicator values.

India COVID-19 Economic Indicators

The COVID-19 data provides detail with the following fields for users:

  • DSPLY_NMLL: Display Name
  • COUNTRY: Country code
  • CF_DATE: Announcement Date
  • ECON_ACT: Actual value
  • ECON_PRIOR: Previous value

We will use Thailand New Cases history data from 1st January 2021 to 3rd May 2021 with Eikon Data API get_timeseries function as an example data for Plotly.

Thailand COVID-19 historical data

Plotting Graph with Plotly Python

Like Matplotlib, Plotly also provides various low-level, high-level, helpers interfaces to create, manipulate and render graphical figures such as charts, plots, maps, diagrams, etc based on developer preference.

The Plotly Python figures are represented by tree-like data structures which are automatically serialized to JSON for rendering by the Plotly.js JavaScript library. Plotly provides the Graph Object as the low-level interface that wraps figures into a Python class and Plotly Express as the high-level interface for creating graphs.

Plotly Express

The Plotly Express package is the recommend entry-point to the Plotly Python library. It is the high-level interface for data visualization. The plotly.express module (usually imported as px) contains functions that can create entire figures at once and is referred to as Plotly Express or PX. Plotly Express is a built-in part of the plotly library and is the recommended starting point for creating the most common figures.

Plotly Express provides more than 30 functions for creating different types of figures. The API for these functions was carefully designed to be as consistent and easy to learn as possible.

We will start with the Line Graph interface.

Line Plot with Plotly Express

The Line Plot interface is the easy-to-use function to create a 2D line graph using px.line() function.

We will plot a single line graph of Thailand COVID-19 new cases historical data with Date value as an X-axis and VALUE as the y-axis. We need to re-structure the Pandas Dataframe to include the Date index as a data column instead.

Thailand COVID-19 historical data after reset index

We create the Plotly Figure object for the line chart with Plotly Express px.line() function. We pass the Date column as x-axis, VALUE column as y-axis, and the chart title information to the function.

Then we use the Figure update_traces() method to update figure traces such as line color and update_yaxes() method to update a figure's y-axes information.

Finally, we call the Figure show() function to draw a chart on Jupyter Notebook. Please noticed that we pass 'notebook' to the function to force the classic Jupyter notebook renderer for the classic Jupyter Notebook environment. If you are using JupyterLab, you can use just fig.show() statement.

Thailand COVID-19 historical data chart

Multiple Lines Graph

The Plotly Express Line also supports a multiple-lines graph. We use COVID-19 new cases data for the USA, India, Brazil, France, and Russia as example data to demonstrate the new case trends from 1st January 2021 to 3rd May 2021.

World COVID-19 historical data

The current column names are the RIC names (USNCOV=ECIINNCOV=ECI, etc.) which are hard to read, so we need to rename the column names to be readable Country names first.

World COVID-19 historical data with rename columns

Then we reset the Dataframe index to include the Date as a data column.

To plot multiple lines graph, we call the px.line() function by passing a list of column names as y-axis values.

World COVID-19 historical data chart

Please see more detail regarding the Plotly Express Line chart in the following resources:

Pie Chart with Plotly Express

The Pie Chart interface is the easy-to-use function to create a circular statistical chart using px.pie() function.

We will look into the India COVID-19 Today all data(Total Cases, New Cases, Active Cases, Recovered Cases, Death Cases) in detail, and plot data as a Pie Chart.

India Today Covid-19 data

In some cases, the Today data (ECON_ACT field) may be return (Nullable integer) based on the Day and Time that you execute the get_data function (most likely on the Fist day of the week).

To handle this situation, we need to check if all values in ECON_ACT column are null or not.

The returned DataFrame object looks fines but it is a bit too hard to read, so we will add a new column named Description to the DataFrame object which contains information about each Instrument definition.

India Today Covid-19 data with description

Finally, we call px.pie() function to create a figure object for a pie chart with the value of ECON_ACT (Actual value) field and Description column name.

For this pie chart, we use the Figure update_traces() method to update text display format on a figure.

For CodeBook Users!!

Please note that the CodeBook application has an older version of Plotly Python (version 4.5.2 as of May 2021), so px.pie() function for CodeBook will be slightly different.

India COVID-19 historical data pie chart

Please see more detail regarding the Plotly Express Pie chart in the following resources:

Plotly Graph Object

The Plotly Graph Object (plotly.graph_objects, typically imported as go) is the low-level interface that lets developers interact with Plotly Figure and IPYWidgets compatible for plotting graphs and manage data in detail. While the Plotly Express provides a simple way to create and customize graphs, the Plotly Graph Object lets developers create and customize more advanced graphs such as Group Bar Chart, Candlestick, Subplot of different types, etc.

"Exploded" Pie Chart with Plotly Graph Object

The above pie chart has some sections that hard to read, so we will re-create that pie chart with Plotly Graph Object to pull out some sectors from the chart.

India COVID-19 historical data pie chart pull-out

Please notice that you can set the chart title via the title property of fig.update_layout function when using the Graph Object.

Please see more detail regarding Plotly Graph Object Bar Chart in the following resources:

Bar Chart with Plotly Graph Object

We will use the Environmental, social and corporate governance (ESG) data of the Telecommunication companies as an example data for the Bar Chart example.

The ESG Data is available in Eikon/Refinitiv Workspace desktop application by a query for ESG in the menu.

ESG Main Menu

You can find ESG data fields from Eikon/Refinitiv Workspace Data Item Browser ("DIB") application and then choosing "Environmental, social and corporate governance" content classification.

ESG data fields

Firstly, we get the ESG Score data from the TR.TRESGScore field via Eikon Data API get_data() function.

ESG Score

Then we create a Plotly Figure for the bar chart with go.Figure interface and go.Bar() class, then pass DataFrame Instrument column as the x-axis and ESG Score column as the y-axis.

Please notice that now we use the Figure update_layout() method to update figure's layout for the chart title.

ESG Score bar chart

However, the ESG Score data alone cannot be used without comparing it with the EST Controversies Score (field TR.TRESGCControversiesScore) and ESG Combined Score (field TR.TRESGCScore).

We will request the Company Name (TR.CompanyName), the ESG Scores to plot a group bar chart.

ESG Scores

Then we create multiple go.Bar objects for each ESG score and pass it to go.Figure. Please notice that we need to set the layout to be a group bar chart via fig.update_layout(barmode='group') statement.

ESG Scores bar chart

Please see more detail regarding Plotly Graph Object Bar Chart in the following resources:

Candlestick Chart with Plotly Graph Object

The last example is the Candlestick charts using Plotly Graph Object. We will use Bitcoin/US Dollar FX Spot Rate as an example dataset that is suitable for the candlestick chart.

The Bitcoin/US Dollar FX Spot Rate data is available in Eikon/Workspace and Refinitiv Real-Time as BTC= instrument name.

Bitcoin data in Workspace

We request 180 daily historical data of BTC= via Eikon Data API get_timeseries function.

Bitcoin data

Then we re-structure the DataFrame index to change the *Date* column from an index column to a data column.

Bitcoin data after reset index

Finally, we use the go.Candlestick object to create the candlestick chart from Dataframe, and pass it to go.Figure to create a Plotly Figure object to plot a graph.

candlestick chart

We can interact with the chart range slider bar too.

candlestick chart interaction

Please see more detail regarding Plotly Graph Object Candlestick Chart in the following resources:

Eikon Data API Setup

Please follow a step-by-step guide to set up your Eikon Data API and your AppKey in Eikon Data API Quick Start page.

How to run the example Notebooks

Please note that the Refinitiv Workspace/Eikon application integrates a Data API proxy that acts as an interface between the Eikon Data API Python library and the Eikon Data Platform. For this reason, the Refinitiv Workspace/Eikon application must be running when you use the Eikon Data API Python library.

The first step is to unzip or download the example project folder from GitHub into a directory of your choice, then follow the step-by-step guide in the GitHub repository:

Troubleshooting

Sometimes the classic Jupyter Notebook encounters the problem when you close the notebook window and re-open it, your plots render as blank spaces.

Notebook Blank render when re-open

You can check if the notebook document is trusted on the top-right menu of the notebook application.

Notebook Trusted

Please click that button to enable JavaScript for display in this notebook.

Notebook Trusted resolve

As a last resort, you can "Restart & Clear Output" from the Kernel menu and rerun your notebook. You can find more detail on Jupyter Classic Notebook Problems and Troubleshooting pages.

Conclusion

Data visualization is the first impression of data analysis for the readers. Data Scientists, Financial coders, and Developers take time on the data visualization process longer than the time they use for getting the data. It means the data visualization/chart library need to be easy to use, flexible and have a good document.

Plotly Python provides both ease-of-use/high-level and low-level interfaces for supporting a wide range of Developers' skills. Developers can pick the Plotly Chart object (line, bar, scatter, candlestick, etc) that match their requirements, check the Plotly example code and community page to create a nice chart with readable and easy to maintain source code.

When compare to the Matplotlib Pyplot (which is the main player in the Charting library), the Plotly advantages and disadvantages are the following:

Pros

  1. Use a few lines of code to create and customize the graph.
  2. Provide more than 30 ease-of-use various chart object types for Developers.
  3. Experience Developers can use the low-level chart object types to create a more powerful and flexible chart.
  4. Simplify documents and example code.
  5. Provide a dedicated paid support program for both individual and corporate developers.

Cons

  1. Some API Interface and installation processes for Classic Jupyter Notebook and Jupyter Lab are different.
  2. Matplotlib Pyplot has larger users based on developer community websites (such as StackOverflow). It means a lot of Pyplot questions, problems will be easy to find the answers or solutions than Plotly.
  3. Matplotlib Pyplot has larger documents, tutorials, step-by-step guide resources from both official and user-based websites.
  4. The plots render as blank spaces sometimes when you reopen the classic Jupyter Notebook (see troubleshooting page)

At the same time, the Eikon Data API lets developers rapidly access Refinitiv Eikon/Refinitiv Workspace data and our latest platform capabilities with a few lines of code that easy to understand and maintain.

Introduction to Dash Plotly - Data Visualization in Python

How to make plots using Plotly

Plotly is a plotting ecosystem that allows you to make plots in Python, as well as JavaScript and R. This is a Python blog, so we’re focusing on the Python libraries.

Plotly has three different Python APIs, giving you a choice of how to drive it:

We’ll explore each of these APIs by making the same plot in each one: a grouped bar plot of historical UK election results.

Making plots using Graph Objects

Plotly’s object-oriented API is named . It’s somewhat similar to Matplotlib’s object-oriented API.

To create our multi-bar plot, we can construct a object containing four plots:

Unlike in Matplotlib, there’s no need to calculate the x-positions of the bars manually; Plotly takes care of that for us.

Here’s the final plot:

Our multibar plot made using Graph Objects.

Making plots using Python data structures

You can also specify your plot using basic Python data structures with the same structure as the object-oriented API. This corresponds directly to the JSON API for Plotly’s Javascript implementation.

The final plot looks exactly the same as our previous plot:

Our multibar plot made using JSON-like data structures.

Making plots using Plotly Express

Plotly Express is a high-level API that wraps Graph Objects.

You can make a multi-bar plot in Plotly Express using (almost) a single line:

This makes use of the data in Long Form, also known as ‘tidy data’. The columns are ‘year’, ‘seats’ and ‘party’ rather than being split by party. It’s very similar to making a multibar plot in Seaborn.

We can access the underlying Graph Objects API to make detailed tweaks. Let’s add a title and y-axis label:

And finally, ask Plotly to show it to us:

This runs a temporary web server on an unused port, and opens the default web browser to view the plot (the web server is immediately torn down).

Unfortunately, the result is not perfect. The x-axis is treated as an integer, so the groups are far apart and small. This makes it quite difficult to see trends.

Our multibar plot made using Plotly express.

You might try to attempt to encourage Plotly Express to treat the x-values as strings by casting them to strings. You might expect this to result in them being plotted with even spacing and lexical ordering. Unfortunately, you still get them helpfully spaced numerically. Setting the does not work as it did in either.

Unlike the similar example in Seaborn, in this case the abstraction did not appear to provide sufficient escape hatches to let us get things exactly how we wanted. But perhaps we could write our own API?

Building your own Plotly API

Not happy with how Plotly does something? Build your own Plotly API!

At its core, Plotly is a JavaScript library that makes plots using D3 and stack.gl. The JavaScript library has an interface that consumes JSON structures that specify plots. So you just need to output JSON structures that the JavaScript library likes to consume.

We did just that to create a Python Plotly API that works entirely in the browser.

Plotly uses a JavaScript library to create plots, driven by libraries in other languages via JSON.

In the Anvil version, you can use both the Graph Objects API and the Python data structure approach explained above. You run exactly the same commands, assigning the and to a Plot component in your Anvil app.

Here’s the multi-bar plot written in Anvil’s client-side Python API:

The plotting logic is the same as above, but it’s running entirely in the web browser - the plot is created by the Plotly JavaScript library on the user’s machine! This is a big advantage over all the other libraries in our rundown of Python plotting libraries. All the other Python libraries need to run on a server.

Here’s the interactive Plotly plot running in an Anvil app:

You can copy this example as an Anvil app here:

Open in Anvil

Running Plotly in the front-end has another advantage: it opens up many more options for customising interactive behaviour.

Customising interactivity in Plotly

Plotly plots aren’t just dynamic, you can customise their interactive behaviour. For example, you can customise the format of tooltips using in each bar plot:

Here’s what we get when we apply this to each bar plot:

Our multibar plot with custom tooltips.

We’ll see a similar approach when we look at Bokeh.

This is useful, but it would be even better if we could execute any code we wanted when certain events happen - let’s say a user hovers over the bar and we want to display an information box about the relevant election. In Anvil’s Plotly library, you can bind event handlers to events such as , which makes that sort of complex interactivity possible!

Our multibar plot with a hover event handler.

We achieve this by binding a method to the plot’s event:

This is a rather extreme level of interactivity, and from the developer’s point of view, an extreme level of customisability. It’s all thanks to Plotly’s architecture - Plotly gives you a clean interface that is explicitly designed to allow you to build your own APIs. We would like to see this kind of great design everywhere!

Next up: custom interactivity using Bokeh

We’ve seen how Plotly uses JavaScript to create dynamic plots, and you can edit them live in the browser using Anvil’s client-side Python code.

We’ll continue our rundown of Python plotting libraries with Bokeh, which outputs an HTML document you can embed in a web app and get similar dynamic features to those provided by Plotly:

(That’s “BOE-kay”, if you’re wondering how to pronouce it.)

Plotly - Package Structure



Plotly Python package has three main modules which are given below −

  • plotly.plotly
  • plotly.graph_objs
  • plotly.tools

The plotly.plotly module contains functions that require a response from Plotly's servers. Functions in this module are interface between your local machine and Plotly.

The plotly.graph_objs module is the most important module that contains all of the class definitions for the objects that make up the plots you see. Following graph objects are defined −

  • Figure,
  • Data,
  • ayout,
  • Different graph traces like Scatter, Box, Histogram etc.
Plotly Module

All graph objects are dictionary- and list-like objects used to generate and/or modify every feature of a Plotly plot.

The plotly.tools module contains many helpful functions facilitating and enhancing the Plotly experience. Functions for subplot generation, embedding Plotly plots in IPython notebooks, saving and retrieving your credentials are defined in this module.

A plot is represented by Figure object which represents Figure class defined in plotly.graph_objs module. It’s constructor needs following parameters −

import plotly.graph_objs as go fig = go.Figure(data, layout, frames)

The data parameter is a list object in Python. It is a list of all the traces that you wish to plot. A trace is just the name we give to a collection of data which is to be plotted. A trace object is named according to how you want the data displayed on the plotting surface.

Plotly provides number of trace objects such as scatter, bar, pie, heatmap etc. and each is returned by respective functions in graph_objs functions. For example: go.scatter() returns a scatter trace.

import numpy as np import math #needed for definition of pi xpoints=np.arange(0, math.pi*2, 0.05) ypoints=np.sin(xpoints) trace0 = go.Scatter( x = xpoints, y = ypoints ) data = [trace0]

The layout parameter defines the appearance of the plot, and plot features which are unrelated to the data. So we will be able to change things like the title, axis titles, annotations, legends, spacing, font and even draw shapes on top of your plot.

layout = go.Layout(title = "Sine wave", xaxis = {'title':'angle'}, yaxis = {'title':'sine'})

A plot can have plot title as well as axis title. It also may have annotations to indicate other descriptions.

Finally, there is a Figure object created by go.Figure() function. It is a dictionary-like object that contains both the data object and the layout object. The figure object is eventually plotted.
