I was trying to write a quick-and-dirty script to generate plots easily. For that, I was using the following code (I took it from the Matplotlib documentation):

from pylab import figure, axes, pie, title, show 

# Make a square figure and axes 

figure(1, figsize=(6, 6)) 

ax = axes([0.1, 0.1, 0.8, 0.8])

labels = 'Frogs', 'Hogs', 'Dogs', 'Logs'

fracs = [15, 30, 45, 10]

explode = (0, 0.05, 0, 0) 

pie(fracs, explode=explode, labels=labels, autopct='%1.1f%%', shadow=True) 

title('Raining Hogs and Dogs', bbox={'facecolor': '0.8', 'pad': 5}) 


# Actually, don't show, just save to foo.png

But I don't want to display the plot on a GUI, instead, I want to save the plot to a file (say foo.png), so that, for example, it can be used in batch scripts. How do I do that?

When you are using Save plot you can use specify .savefig() as an extension to the file:-

from matplotlib import pyplot as plt



The use of  .savefig() Will give a rasterized or vectorized output respectively, both which could be useful.

You can also refer to the below link as with the help of the below code, you can able to reopen the image whenever you want:

import matplotlib.pyplot as plt

fig, ax = plt.subplots( nrows=1, ncols=1 )  # create figure & 1 axis

ax.plot([0,1,2], [10,20,3])

fig.savefig('path/to/save/image/to.png')   # save the figure to file

plt.close(fig)    # close the figure window

For more information regarding the same, do refer to the Python certification course.
