Matplotlib.pyplot.colors() in Python
  • Last Updated : 03 May, 2020

In Python we can plot graphs for visualization using Matplotlib library. For integrating plots into applications, Matplotlib provides an API. Matplotlib has a module named pyplot which provides a MATLAB-like interface.

Matplotlib.pyplot.colors()

This function is used to specify the color. It is do-nothing function.

AliasColor
‘b’Blue
‘r’Red
‘g’Green
‘c’Cyan
‘m’Magenta
‘y’Yellow
‘k’Black
‘w’White

We can use this function for various data visualizations and obtain insights from them.

Examples 1:




import matplotlib.pyplot as plt
  
  
# Define the Color
color = 'green'
plt.plot([1, 2, 3, 4], color = color)
  
plt.show()

Output:



pytohn-matplotlib-color-1

Example 2:




import matplotlib.pyplot as plt
  
  
x = [1, 2, 3, 4]
y= [1, 4, 9, 16]
  
plt.plot(x, y, marker = 'o', markerfacecolor = 'r')
  
plt.show()

Output:

python-matplotlib-color-2

Here, marker=’o’ represents circle while markerfacecolor is used for specifying color of the point marker.

Note: This function has been deprecated since version 2.1.
