To fill an area within a polygon in Python using matplotlib, we can take the following steps −
Steps
Set the figure size and adjust the padding between and around the subplots.
Create a figure and a set of subplots.
Get an instance of a polygon.
Get the generic collection of patches with iterable polygons.
Add a 'collection' to the axes' collections; return the collection.
To display the figure, use show() method.
Example
import matplotlib.pyplot as plt from matplotlib.collections import PatchCollection from matplotlib.patches import Polygon import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True fig, ax = plt.subplots(1) polygon = Polygon(np.random.rand(6, 2), closed=True, alpha=1) collection = PatchCollection([polygon]) ax.add_collection(collection) plt.show()
Output
It will produce the following output −
