How to save a plot to an Image file in Matplotlib?

Apart from showing the plot, Matplotlib also enables you to save the plot as a PNG, JPG, and SVG.

To save the plot as an image file, you must call the savefig() function and pass the filename with the .png or .jpg extension.

import matplotlib.pyplot as plt
 
#Code for plotting the graph

plt.savefig('output.png') #save the plot as PNG file
plt.savefig('output.jpg') #save the plot as JPG file
plt.savefig('output.svg') #save the plot as SVG file

Note: If you are running plt.show() and plt.savefig() functions then make sure plt.savefig() comes before plt.show().

In this code, we will draw a line chart and save it as "sales.jpg".

import matplotlib.pyplot as plt

x = [2004, 2005, 2006, 2007]
y = [1102, 2274, 900, 1482]

plt.plot(x, y, color='red')
plt.title('Yearly Sales Data')
plt.xlabel('Years')
plt.ylabel('Sales')

plt.savefig('sales.jpg')
