Hi Eric, thanks for the help, but this doesn't do what I want. I don't want to change the image in any way, I just want the axes to have a decreasing spacing. I made a small example with ms paint to clarify.
http://www.nabble.com/file/p25867951/axes.png I could do this with ax.set_xticks() and ax.set_xticklabels(), but I was wondering if there is a way that also changes the whole coordinate system and not only the labeling. For example, the position of the mouse pointer will not be shown anymore when I use custom ax.set_xticklabels().
