matplotlib legend goes outside of the window area

Question

As you can see in the picture below, the legend with its box goes outside of the figure area on the horizontal line.

Note that I cropped the upper part since the problem is with the width.

The matplot script is rather lengthy and most of the code is not relevant to this question. In short, I have

 fig = plt.figure(1,figsize=(10.67,6.6))
 ...
 leg1 = plt.legend(handles = marker_handles,bbox_to_anchor=(1.2,1),loc='upper right', ncol=1)
 ax.add_artist(leg1)
 ...
 plt.savefig(filename+'.png')
 plt.show()

If I increase the figsize, then plt.show() shows a very big window and still the legend goes beyond the window border.

How can I fix that?

Answer 1

either use

plt.tight_layout() to automatically adjust the dimensions of the Axes to accomodate the legend box

or, if you prefer more fine control:

plt.subplots_adjust(right=xxxx) to shrink the width of the Axes to accomodate the legend box
