Ah, would be nice to make this clear in the docs. So far was doing


import pylab
F = pylab.gcf()
F.set_tight_layout(True)

which as you say does not help the way I thought.


Unfortunately, while

fig.savefig('foobar.png', bbox_inches='tight')

helped to get everything into the .png file (attached), the barchart itself
should span according to the code I posted just 1/2 of the figure. But somehow
it is enlarged and rescaled so that it occupies *more than* 1/2 of the figure.
What in pylab is resizing my image? Note: the final image is 625x1075.
