[Matplotlib-users] pcolorfast and log axes.

[Daniel W. <dan...@gm...>]

Greetings.

I've recently found that when I replace pcolor with pcolorfast, the image
will not scale correctly when placed on an axis with a logarithmic scale.
 It will remain linear, thus not matching the axis range whatsoever.  The
pcolor plot will still fit nicely in the axis object, but the ticks and
labels clearly do not match the data.  I've tried several things, from
changing the axis from linear to log before and after using pcolorfast, etc,
but pcolorfast artist objects do not seem to respond to this.  Again, pcolor
acts as one would expect.

Complicating this is that I have made two changes at once: upgrading from
MPL 99 to 1.0 and switching from pcolor to pcolorfast.  As such, I do not
know if this a new or old issue (or if it is an issue at- perhaps this
behavior is on purpose.)

If anyone could shed some light on this, that would be great.  Pcolorfast is
preferable over pcolor because of the complexity of my plots and the speed
up gained by using pcolorfast.

Thanks!
