[Matplotlib-users] Using color in fill

[Carol L. <car...@sr...>]

I am using fill to make filled polygons.  I want to fill the polygons 
with colors that reflect data values, similar to what imshow does.

Is there a way to extract the rgb tuples from a Colormap? This could be 
an array of N tuples, each tuple containing 3 0-1 floats that describe 
the color or three separate arrays, one each for red, green and blue.

I made the mistake of using some non-public attributes of the class 
colorMap to accomplish this in a previous version of matplotlib.  That 
was a mistake since Colormap._red_lut, Colormap._green_lut and 
Colormap._blue_lut no longer exist.

Once I have the array of tuples, I can determine which one I want and 
create a hex string using rgb2hex to get a color suitable for use with fill.

I need the flexability to make the same plot using several different 
color maps.
