I agree, and this is a problem with spy also. If I remember, I will fix it. It is only a minor annoyance, so it is low priority, though. There is a difference in the way the axes are labeled between spy and matshow, and I would like to change matshow to agree with spy, unless there is an outcry to the contrary. Specifically, I think the integer axis ticks should land in the middle of a given row or column, not on the edge. To see what I mean, compare xx = zeros((3,3)) xx[1,1] = 1 spy(xx, marker='s') to matshow(xx) Maybe this is exactly what you mean by your next statement? > > Further, I would think a setting like align='center' in pylab.bar() would > be appropriate.
