To set color to a rectangle in matplotlib, we can take the following steps −
Create a figure or activate an existing figure using figure() method.
Add an '~.axes.Axes' to the figure as part of a subplot arrangement using add_subplot() method.
A rectangle is defined via an anchor point with width and heights.
Add a rectangle patch to the plot.
Set the x and y limit using xlim() and ylim() method.
To display the figure, use show() method.
Example
from matplotlib import pyplot as plt, patches plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True fig = plt.figure() ax = fig.add_subplot(111) rectangle = patches.Rectangle((0, 0), 3, 3, edgecolor='orange', facecolor="green", linewidth=7) ax.add_patch(rectangle) plt.xlim([-5, 5]) plt.ylim([-5, 5]) plt.show()
