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. For better understanding refer to Example2Returns: A list of Polygon
Other Parameters:
**kwargs: Supports all other properties of Polygon patch.
Example 1:
# 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 2:
# 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

Output:
