Intermediate Python: Next-level Data Visualization

May 4 @ 10:00 am - 12:00 pm

Description: Take your data visualization skills to the next level in Python! In this intermediate Python workshop we’ll cover the fundamentals of Matplotlib, which is the foundation for most Python visualization packages. Then we’ll discuss how to choose appropriate visualizations for your data and how to critically assess your visualizations for potential problems. We’ll then put it all together to practice using Matplotlib to fix and improve visualizations made with Python packages including Plotnine, Seaborn, and Pandas.

This workshop is NOT an introduction to Python and is intended for motivated intermediate to advanced learners from all domains at UC Davis who want to hone their Python skills. Please make sure you meet the prerequisites before registering as we will be unable to answer introductory Python questions during this session. This workshop builds upon your existing knowledge of working in Python and upon the concept of tidy data. Learners should also attend the Principles of Data Visualization from Perception to Statistical Graphics workshop in advance of this session to ensure a solid foundation in design principles. (Want to brush up on Python? Check out our Python Basics 4-part introductory series.)

Learning Objectives

After completing this workshop, learners should be able to:

  • – Describe and identify the components of a Matplotlib Figure
  • – Explain the difference between Matplotlib’s explicit and implicit interfaces
  • – Create and modify Matplotlib plots with Figure and Axes methods
  • – Describe Matplotlib’s memory model
  • – Choose appropriate visualizations based on data type(s)
  • – List the steps to making a well-designed visualization
  • – Use Matplotlib to customize visualizations made with other packages


Prerequisites: Participants must have taken DataLab’s “Python Basics” workshop series and/or have prior experience using Python, be comfortable with basic Python syntax, and have it pre-installed and running on their laptops. Learners should also take the Principles of Data Visualization from Perception to Statistical Graphics workshop in advance of this session.

Software: A recent version of Python 3 and these packages:

  • – jupyterlab
  • – pandas
  • – matplotlib
  • – seaborn
  • – plotnine
