Draw a stacked area plot or a streamgraph. Parameters: x(N,) array-like. y(M, N) array-like. The data is assumed to be unstacked. Each of the following calls is legal: stackplot(x, y) # where y has shape (M, N) stackplot(x, y1, y2, y3) # where y1, y2, y3, y4 have length N. Copy to clipboard.
Stackplots draw multiple datasets as vertically stacked areas. This is useful when the individual data values and additionally their cumulative value are of interest.

16 gru 2021 · Stackplot is used to draw a stacked area plot. It displays the complete data for visualization. It shows each part stacked onto one another and how each part makes the complete figure. It displays various constituents of data and it behaves like a pie chart.
Stack Plots with Matplotlib. In this Matplotlib data visualization tutorial, we cover how to create stack plots. The idea of stack plots is to show "parts to the whole" over time. A stack plot is basically like a pie-chart, only over time.
To create a StackPlot, we use the stackplot function from pyplot. Instead of passing an X and Y, we pass an X (in our case days), then we pass multiple arrays that represent our categories. Each item in the category is the amount of Y (in our case budget spent on ads). import matplotlib.pyplot as plt. days = [1, 2, 3, 4, 5] .
