Data Visualization | Matplotlib Text Boxes | Styling Tips

Introduction

In data visualization, it is important to highlight specific information to draw the viewer's attention. One way to do this is by styling text boxes using bbox parameters in Matplotlib. In this lab, we will learn how to style text boxes using bbox parameters in Matplotlib.

VM Tips

After the VM startup is done, click the top left corner to switch to the Notebook tab to access Jupyter Notebook for practice.

Sometimes, you may need to wait a few seconds for Jupyter Notebook to finish loading. The validation of operations cannot be automated because of limitations in Jupyter Notebook.

If you face issues during learning, feel free to ask Labby. Provide feedback after the session, and we will promptly resolve the problem for you.

Import Required Libraries

import matplotlib.pyplot as plt

Create a Text Box

plt.text(0.6, 0.7, "eggs", size=50, rotation=30.,
         ha="center", va="center",
         bbox=dict(boxstyle="round",
                   ec=(1., 0.5, 0.5),
                   fc=(1., 0.8, 0.8),
                   )
         )

We create a text box containing the word "eggs" using the text() method. The bbox parameter is used to style the box. The boxstyle parameter is set to "round" to create a rounded box, while ec and fc parameters set the edge and face colors of the box, respectively. The size parameter sets the font size, rotation parameter sets the rotation angle, and ha and va parameters set the horizontal and vertical alignment of the text in the box.

Create Another Text Box

plt.text(0.55, 0.6, "spam", size=50, rotation=-25.,
         ha="right", va="top",
         bbox=dict(boxstyle="square",
                   ec=(1., 0.5, 0.5),
                   fc=(1., 0.8, 0.8),
                   )
         )

We create another text box containing the word "spam". This time we set boxstyle parameter to "square" to create a square box and set ha and va parameters to "right" and "top" to align the text to the right and top of the box.

Display the Plot

plt.show()

Finally, we display the plot by calling the show() method.

Summary

In this lab, we learned how to style text boxes using bbox parameters in Matplotlib. By using the bbox parameter, we can create boxes of different shapes and colors to highlight specific information in our visualizations.
