How to Draw a Stack Plot

Explore how to draw stack plots using Matplotlib to visualize changing parts of a whole over time. Learn about the stackplot function, its parameters, and how to adjust the baseline to enhance your data storytelling.

As we know that, the pie chart is an effective way to show the proportion of individual pieces of data as they relate to the data overall. One drawback of such charts is that they only show the data of a given moment. They do not show how parts of a population change over time. We can use stackplot to show how parts of the whole change over time.

stackplot() is the basic function that Matplotlib provides to create a stack plot. Below are some of the important parameters required by the function:

  • x: 1d array of dimension N
  • y: 2d array, dimension(
