How can I create a stacked line graph with matplotlib?
To create a stacked lines graph with Python, we can take the following Steps −
Create x, y, y1 and y2 points using numpy.
Plot the lines using numpy with the above data (Step 1) and labels mentioned.
Fill the color between curve y=e^x and y=0, using the fill_between() method.
Fill the color between curve y=2x and y=0, using the fill_between() method.
Fill the color between curve y=log(x) and y=0, using fill_between() method.
Place the curve text using the legend() method.
To display the figure, use the show() method.
Example
import matplotlib.pyplot as plt import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(1, 5, 100) y = x * 2 y1 = np.log(x) y2 = np.exp(x) plt.plot(x, y, label=r'$y=2^x$') plt.plot(x, y1, label=r'$y=\log{x}$') plt.plot(x, y2, label=r'$y=e^x$') plt.fill_between(x, y2, 0, color='orange') plt.fill_between(x, y, 0, color='blue') plt.fill_between(x, y1, 0, color='red') plt.legend() plt.show()
