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.


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)
plt.text(0, 0.5, "Rectangle")
plt.xlim([-4, 4])
plt.ylim([-4, 4])
