The following program code shows how you can plot a newline in matplotlib label with Tex.
Steps
Setup X-axis and Y-axis labels for the diagram with \n to plot a newline in the labels.
Set the current .rcParams for axes facecolor; the group is axed.
Use a cycler to set the color for the group of lines. The color list consists of ‘r’ for red, ‘g’ for green, ‘b’ for blue, and ‘y’ for yellow.
The cycler class helps to create a new Cycler object from a single positional argument, a pair of positional arguments, or the combination of keyword arguments.
Plot the number of lines with different colors.
Use plt.show() to show the figure.
Example
import matplotlib.pyplot as plt
from cycler import cycler
plt.ylabel("Y-axis \n with newline")
plt.xlabel("X-axis \n with newline")
plt.rc('axes', prop_cycle=(cycler('color', ['r', 'g', 'b', 'y'])))
plt.plot([0, 5])
plt.plot([2, 6])
plt.plot([3, 8])
plt.plot([4, 9])
plt.show()Output
