imshow scaling

Community matplotlib-users
#1

Is there a way to make imshow scale images to dimensions other than that of
the arrya passed to it? I'm trying to plot a long matrix (like 23x5000) and
imshow doesn't work very well since it makes a very vertically thin plot and
its hard to see anything. I would like the image to dynamically scale with
windows size like if you plotted something with specgram() or plot().

Thanks,

Ryan

Explicitly set the aspect to "auto".

  imshow(image, aspect="auto")

Just pass in aspect='auto' as a keyword argument to imshow.
