Plot a rectangle with an edgecolor in Matplotlib

To put edgecolor of a rectangle in matplotlib, we can take the following Steps −

Create a new figure or activate an existing figure using figure() method.
Add a subplot method to the current axis.
Create a rectangle instance using Rectangle() class with an edgecolor and linewidth of the edge.
Add a rectangle path on the plot.
To place the text in the rectangle, we can use text() method.
Scale x and y axes using xlim() and ylim() methods.
To display the figure, use show() method.

Example

import matplotlib
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)
rect = matplotlib.patches.Rectangle((-1, -1), 3, 3, edgecolor='orange', facecolor="green", linewidth=5)
ax.add_patch(rect)
plt.text(0, 0.5, "Rectangle")
plt.xlim([-4, 4])
plt.ylim([-4, 4])
plt.show()
