Matplotlib.axes.Axes.get_facecolor() in Python

  • Last Updated : 19 Apr, 2020

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.

matplotlib.axes.Axes.get_facecolor() Function

The Axes.get_facecolor() function in axes module of matplotlib library is used to get the facecolor of the Axes..

Syntax: Axes.get_facecolor(self)

Parameters: This method does not accept any parameters.

Returns:This method returns value of the facecolor of the Axes.



Below examples illustrate the matplotlib.axes.Axes.get_facecolor() function in matplotlib.axes:

Example 1:




# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
    
x = np.arange(-5, 5, 0.01)
y1 = -3 * x*x + 10 * x + 10
y2 = 3 * x*x + x
    
fig, ax = plt.subplots()
ax.plot(x, y1, x, y2, color ='black')
ax.fill_between(x, y1, y2, where = y2 >y1,
                facecolor ='green', alpha = 0.8)
ax.fill_between(x, y1, y2, where = y2 <= y1,' 
               facecolor ='black', alpha = 0.8)
  
x = ax.get_facecolor()
ax.text(-2, 80, "Value of facecolor : " +str(x),
        style ='italic', fontsize = 10
        color ="green")
ax.set_title('matplotlib.axes.Axes.get_facecolor()\
 Example\n', fontsize = 12, fontweight ='bold')
plt.show()

Output:

Example 2:




# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
   
data = ((30, 1000), (10, 28), (100, 30),
        (500, 800), (50, 10))
   
dim = len(data[0])
w = 0.6
dimw = w / dim
   
fig, ax = plt.subplots()
x = np.arange(len(data))
for i in range(len(data[0])):
    y = [d[i] for d in data]
    b = ax.bar(x + i * dimw, y, dimw, bottom = 0.001)
   
ax.set_xticks(x + dimw / 2)
ax.set_xticklabels(map(str, x))
ax.set_yscale('log')
  
x = ax.get_facecolor()
ax.text(1, 2.3*(10**3), "Value of facecolor : " +str(x), 
        style ='italic', fontsize = 10
        color ="green")
ax.set_title('matplotlib.axes.Axes.get_facecolor()\
 Example\n', fontsize = 12, fontweight ='bold')
plt.show()
