[Matplotlib-users] origin='upper' nor working with pcolor

[Khem R. <raj...@gm...>]

Hi

I have been trying to plot a matrix and want to start from top left
corner. I tried to use 'matshow' and it worked the way I wanted but
that could not satisfy other needs like I needed to plot something
else over the matrix and also needed shading='faceted' which I could
not set using matshow

So I tried to use 'pcolor' where shading is faceted by default and I
could plot other stuff on top ofI the matrix image but I could not get
the origin='upper' working with pcolor. I also tried with imshow but
it did the same thing.

I tried both lower and upper values and results come out same the
array starts plotting from bottom left.

I am using 0.87.6 and python 2.4.3

Has anybody seen this problem ? Is there usage error?
