Save plot to image file instead of displaying it using Matplotlib

While the question has been answered, I’d like to add some useful tips when using matplotlib.pyplot.savefig. The file format can be specified by the extension:

from matplotlib import pyplot as plt


Will give a rasterized or vectorized output respectively, both which could be useful. In addition, there’s often an undesirable, whitespace around the image, which can be removed with:

plt.savefig('foo.png', bbox_inches='tight')

Note that if showing the plot, should follow plt.savefig(), otherwise the file image will be blank.
