[Matplotlib-users] xticks vs yticks

[Jan S. <js...@sl...>]

I'm having some problems understanding the difference between pylab.xticks()
and pylab.yticks()
Consider the following:

> import pylab as P
> import numpy as N
>
> data = N.random.random((10, 10))
> P.matshow(data)
> P.xticks([0, 1, 2], ['1', '2', '3'])
> P.show()


Why does this work, but if I change P.xticks to P.yticks, it doesn't?

The error message that I get back doesn't give me any insight as to what
could cause the difference between xticks and yticks.

I am still in the learning phase, so any insight as to what's going on is
appreciated.
