- Scatter plot. Scatteplot is a classic and fundamental plot used to study the relationship between two variables. If you have multiple groups in your data you may want to visualise each group in a different color.
- Bubble plot with Encircling. Sometimes you want to show a group of points within a boundary to emphasize their importance. In this example, you get the records from the dataframe that should be encircled and pass it to the encircle() described in the code below.
- Scatter plot with linear regression line of best fit. If you want to understand how two variables change with respect to each other, the line of best fit is the way to go.
- Jittering with stripplot. Often multiple datapoints have exactly the same X and Y values. As a result, multiple points get plotted over each other and hide.
Jan 22, 2019 · Using matplotlib, you can create pretty much any type of plot. However, as your plots get more complex, the learning curve can get steeper. The goal of this tutorial is to make you understand ‘how plotting with matplotlib works’ and make you comfortable to build full-featured plots with matplotlib. 2.

Matplotlib is a plotting package designed to create plots in a similar fashion to MATLAB. The library makes it easy to create a chart with a single line of code, but also provides an extensive (really, it’s huge!) set of customization options. This is great, but it can also make the library very confusing to use. This tutorial is meant to provide a...
Matplotlib is not part of the standard Python library. Because of this, we need to install it before we can use it. Matplotlib is available to install via pip (or conda). Copy the code below into your terminal to install the Matplotlib library: Once you have successfully installed Matplotlib, you can load the library in your Python file. Instead of...
Before diving into creating your first plot using Matplotlib, let’s cover off a bit of theory. In this tutorial, you’ll be using two main components of Matplotlib: 1. Figure: the outermost container for graphing in Matplotlib, which contains one or more axes objects 2. Axes: which contains the region for plotting data, including all individual elem...
Now, let’s create your first Matplotlib graphic! In order to do this, you’ll load a simple Figure containing only one Axes. From there, you can easily pass in two lists of data to plot your data. Let’s first create the Figure and Axesobjects and confirm their types: Here, we created a Figure and an Axes using the subplots() method. Now that we have...
In many cases, your data won’t simply be stored in lists. It’s much more likely that you’ll find yourself working with a data science library, like Pandas. Because of this, this section will teach you how to work with Matplotlib using data stored in a Pandas DataFrame.
Matplotlib provides an incredibly large amount of customization options. It would be impractical to cover off every customization option here, so we will focus on some of the key elements. You’ll learn how to add titles and axis labels, as well as how to modify axis ranges. You’ll also learn how to add legends to your plots and how to change elemen...
In this section, we’ll apply what you learned in the previous sections to create and style a pie chart. Creating a pie chart is very similar to creating a line chart, only instead of using the .plot() method, we use the .pie()method. Matplotlib will expect a series of data that it should plot. Because our DataFrame is a wide format, we can’t simply...
To close off the tutorial, let’s look at a more complex example. We’ll work our way through creating the multiple bar chart below. Throughout this section, you’ll learn more about the .bar()method and how positioning works in Python’s Matplotlib. Insofar, you’ve focused on overlaying lines over one another. In the case of bar charts, this won’t do,...
It’s time to test your learning! Use the exercises below to check your understanding of what you’ve learned in this tutorial. If you need help or want to check your solution, click the question to see a potential solution.
In this tutorial you learned how to use Python and Matplotlib to dive into the world of data visualization. Being able to articulate and explore your data using visualizations can make you a much stronger Pythonista. The section below provides a recap of what you learned: 1. Matplotlib can be installed using pip or conda 2. The pyplotmodule provide...
Introduction to pyplot #. matplotlib.pyplot is a collection of functions that make matplotlib work like MATLAB. Each pyplot function makes some change to a figure: e.g., creates a figure, creates a plotting area in a figure, plots some lines in a plotting area, decorates the plot with labels, etc.
Dec 30, 2020 · Top 50 Matplotlib Plots for Data Analysis. Overview. This tutorial takes you through the following well-rounded concepts: 1. Plotting your first graph. 2. Line style and color. 3. Saving a figure. 4. Subplots. 5. Multiple figures. 6. Pyplot’s state machine: implicit vs explicit. 7. Pylab vs Pyplot vs Matplotlib. 8. Drawing text. 9. Legends. 10.
