Matplotlib.pyplot.fill() function is used to fill the area enclosed by polygon /curve.

Syntax: matplotlib.pyplot.fill(*args, data=None, **kwargs)

Parameters: *args: sequence of x, y, [color] sequence of x,y = To traverse the boundaries of the polygon or curve defined by lists of x and y positions of its nodes.color = To change the default fill color to the desired one.You can plot multiple polygons by providing multiple x, y, [color] groups.data: indexable object, optional default value = none You can directly provide labeled data in the form of a dictionary.

Example 1:

Python3 `

Importing the library

import matplotlib import matplotlib.pyplot as plt import numpy as np

Data for plotting

x = np.arange(0.0, 2.0, 0.01) y = 1 + np.sin(2 * np.pi * x) plt.plot(x, y)

Assighning plot attributes

plt.xlabel("angle") plt.ylabel("sine") plt.title('sine wave')

Filling sign wave curv with cyan color

plt.fill(x, y, "c") plt.show()

Output:

Example 1_Output_GFG

Example 2:

Python3 `

Importing libraries

import matplotlib import matplotlib.pyplot as plt

Below we are using data attribute

plt.fill("j", "k", 'm', data={"j": [0, 1, 2], "k": [0, 1, 0]}) # here 'm' for magenta
