[Matplotlib-users] interpolation and colormaps, over and under colors

[T J <tj...@gm...>]

Hi,

I am plotting with imshow() and interpolation is turned on
('gaussian').  Part of my issue is that the distribution of values is
such that I need to set the over/under colors to grab the most
relevant values.  If I set the over color to be the "maximum" color,
then the result is too dark.  Conversely for the under color.  I can
set the over/under colors to not draw, but then I have "holes" in my
image.  Is it possible to incorporate interpolation?  That is, I would
like to set my over color to be interpolated among its neighboring
cells.  This seems like it would require an (more) "intelligent"
colormap, so my guess is that this isn't currently supported.  I'm
growing more comfortable with the mpl internals and might give a stab
at implementing this, but I'm not quite sure where to start.

Thanks in advance.
