I'm not sure whether I'm correctly understanding you. Let's consider a
hypothetical engineering performance-versus-requirements scatter plot or
contour plot of a performance metric that takes positive values. I'd
like to map values to colors so that anything below 50 gets solid red,

Hi,
I'm trying to get something like texture mapping to work. (I don't need
anything fancy transforms between texel location and image location,
though. I'm happy to specify just a 2D grid of pixel colors that appear
onto a rectangle positioned in 3D space.)
Given that, I made a demo based on pco
I'd like to see a single function that combines ListedColormap and
BoundaryNorm. This function could compare the lengths of the color list
and threshold list to determine what type of colormap is desired. (If
the lengths are the same, then the calling program wants a continuous
colormap; if t

It seems to me that continuous (piecewise-linear) colormaps could work
in much the same fashion. One would specify n boundary colors and n
thresholds (for continuous colormaps, I believe that the number of
thresholds and colors must be the same), and for any value between two

That'd be great. I just installed inkscap

I committed a change to make it run both png and pdf tests all the time.

I went to create a new image comparison test related to the hatching bug
reported this morning.
I added my test to the bottom of test_simplification.py, and ran all the
tests as follows:
python -c "import matplotlib; matplotlib.test()"
