Hi,
I am using the standard matplotlib on Ubuntu 14.04.
I was creating a custom colormap using the standard dict with
rgb values method (something I have done before as well). However,
one of the values in the 'r' array was 55 instead of .55 and contourf
would die saying 'invalid rgb value' which was somewhere near 51.
Ideally, matplotlib should catch this, and I did some digging to see what
is happening. I finally saw this bit of code in 473 in colors.py (in the
function
makMappingArray)
np.clip(lut, 0.0, 1.0)
it appears that np.clip does not modify its arguments and this should
instead
be
lut = np.clip(lut, 0.0, 1.0)
which fixed the problem. Of course, if this error(?) was not there, I would
have
never found the problem in my custom colormap, so not all bad afer all ;)
Thanks,
Joy
