In order to compare values, we can use bar chart in matplotlib. Here is the tutorial:
Matplotlib: Compare Values with Different Color in Bar Chart
However, we also can use multiple line plots to compare. In this tutorial, we will introduce how to draw multiple lines with different color on the same plot.
import matplotlib.pyplot as plt import numpy as np
x = [1, 2, 3, 4, 5, 6] y = [2, 4, 6, 5, 6, 8] y2 = [5, 3, 7, 8, 9, 6]
We should notice: x is shared by y and y2.
3.Draw line plot
fig, ax = plt.subplots() ax.plot(x, y) ax.plot(x, y2) plt.show()
Run this code, you will see this plot.
Moreover, if you want to change the color of each line or add legend, you can do as follows:
ax.plot(x, y, color = 'green', label = 'Line 1') ax.plot(x, y2, color = 'red', label = 'Line 2') ax.legend(loc = 'upper left') plt.show()
