Hi, I once was indicated a way to extract colors from exsiting colormaps:
I just answered a question on Stackoverflow and maybe you can have a look.
all code in pylab mode
a = np.arange(100).reshape(10,10)
#here is the image with white and black end
imshow(a,cmap=mat.cm.binary)
colorbar()
#we e
Thanks for your reply. It's really nice. But, can you provide the code
(part of it) where the colormap start from "very light gray" to "black"
in the range (0,1). And all of the points >1 are black one and =0.0 IS
NOT white. I have 2D map with defined pair (x,y) and the values for
them, but also t

I asked same question with different problem here:

Hi all,
I am a newbie in matplotlib and I'd like to use colormap for z-axis. I
can use in basic mode but would like to shift the existed colormap -
binary - for using in this way:
i would not like to set the white color for z=0.0 For describing: I
would like to use the binary colormap but with
