# Introduction In data visualization, colorbars are used to represent the range of values of a dataset using color. Matplotlib is a Python library for creating a variety of visualizations, including colorbars. In this lab, we will learn how to customize the tick labels on a colorbar 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.
