[Matplotlib-users] colormap shift

[Marian J. <mja...@ta...>]

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 without the white color
because this color I would like to leave for not-defined value for
(x,y). 

Is it possible to do this? Maybe create new colormap on the basis of
the "binary" but without the white color. 

Any suggestions? 

Thanks in advance for your help. 

best, 
Marian
