Dear all,
I find I would like to make some change from the existing colormaps. for
example, I would like to change the color at the beginning of the colormap
(let's say mat.cm.jet) but I still
want to use the remaining other colors. So is there way I can easily use
some functions already in matplotlib to extract the colorlist and levels
from a mat.cm.jet?
Then I can just change the first color of the colorlist, and use
mat.colors.LinearSegmentedColormap.from_list to easily construct the
colormap I want.
I can use mat.cm.jet._segmentdata to retrieve the dictionary. I also have a
look at the source code
/usr/local/lib/python2.7/dist-packages/matplotlib/colors.py but I didn't
manage to find a solution.
both mat.colors.LinearSegmentedColormap and mat.colors.ListedColormap
finally calls mat.colors.Colormap.__init__ and then I don't understand how
these colorlist are really used for plotting.
Another question, where can I find the source code where mat.cm.jet is
defined?
thanks et cheers,
Chao
