In this tutorial, we will introduce how to save matplotlib plot to an image with different dpi and background color.

1.Import library

import matplotlib.pyplot as plt
import numpy as np

2.Create a plot

fig = plt.figure()

x = np.arange(0, 10, 0.1)
y = np.sin(x)

plt.plot(x, y)

3.Save plot image with different dpi

fig.savefig('saved_figure-50pi.png', dpi = 50)
fig.savefig('saved_figure-100dpi.png', dpi = 100)
fig.savefig('saved_figure-1000dpi.png', dpi = 1000)

We can set dpi to save plot image in fig.savefig().

4.Save plot image with different background

plt.savefig('saved_figure-tight.png', bbox_inches = 'tight', facecolor='red')

We can set facecolor to save image in plt.savefig().
