Plt.show shows full graph but savefig is cropping the image

My code is succesfully saving images to file, but it is cropping important details from the right hand side. Answers exist for fixing this problem when it arises for plt.show, but it is the savefig command that is incorrectly producing the graph in this example. How can this be fixed?

The relevant sample of my code:

import glob
import os
for file in glob.glob("*.oax"):
    try:
        spc_file = open(file, 'r').read()
        newName = file[6:8] + '-' + file[4:6] + '-' + file[0:4] + ' ' + file[8:12] +  ' UTC (Observed) - No Sea Breeze Day'
        plt.title(newName, fontsize=12, loc='left')
        plt.savefig('X:/' + newName + '.png')        
        plt.show()
    except Exception:
        pass

And the images (top is plt.show and bottom is file produced from savefig:

You may try

plt.savefig('X:/' + newName + '.png', bbox_inches='tight')

Or you may define figure size like

fig = plt.figure(figsize=(9, 11))
...
plt.savefig(filename, bbox_inches = 'tight')

As described in the documentation you may also try:

plt.tight_layout()

Another very easy solution is saving a plot to a .pdf format. This have worked for me many times when bbox_inches = 'tight'and plt.tight_layout() didn't help.

Syntax is just:

plt.savefig('X:/' + newName + '.pdf')
