[Matplotlib-users] How can I put a white area in the middle of colorbar showing the masked data?

[Chao Y. <cha...@gm...>]

Dear all,

In many cases in geoscience mapping we want to show the some missing values
as some special color in the colorbar. like attached one.

I know there is one method in matplotlib colormap called "set_bad", official
docs says:

Set color to be used for masked values.

But I don't know how to make this work when I call the colorbar method.
Is there anyone who have the some successful experience?

Thanks a lot in advance!

Chao
