Stacked area Chart

A stacked area chart displays the evolution of a numeric variable for several groups of a dataset. Each group is displayed on top of each other, making it easy to read the evolution of the total, but hard to read each group value accurately. In python, stacked area charts are mainly done thanks to the stackplot() function

⏱ Quick start

# library
import numpy as np
import matplotlib.pyplot as plt

# Create data

# Basic stacked area chart.
plt.stackplot(x,y1, y2, y3, labels=['A','B','C'])
plt.legend(loc='upper left')

Matplotlib is the most common way to build a stacked area chart with Python. The examples below start by explaining to basics of the stackplot() function. The also describe the most common type of customization like changing colors, controling group order and more.

The web is full of astonishing charts made by awesome bloggers, (often using R). The Python graph gallery tries to display (or translate from R) some of the best creations and explain how their source code works.
