[Matplotlib-users] register colormap collection

[Eric G. <eg...@gm...>]

Hi all,

I have a question about how to permanently register customs colormap into
matplolib. I went across the cookbook and the definition of cm.register, I
also checked on stack overflow and found this post

http://stackoverflow.com/questions/8738239/permanently-registering-colormaps-in-matplotlib
>

but I still quite don't understand how the registration works, and how to
make the registration working across different scripts.

I have a set of colormap that I manage to transform from their original
format (.cpt or .clr) to matplotlib object :

<matplotlib.colors.LinearSegmentedColormap object at 0x1033406d0>

My first though was that I could register these colormap objects once as
list for exemple, and then call them anytime in any script, the same way we
do call any matploltlib colormap preset with matplotlib.cm.jet etc...

It looks like this is not possible since register a colormap, and call it
using get_map(mycmap) does not work across different script.

I clearly don't get the logic behind the registration of the colormap, and
I am looking for a way to stock all my custom colormap somewhere in a file
or module, that I could import in every script and then call the colormap
the way we call the matplotlib colormap collection, maybe not using
matplolib.cm. but with a custom function similar to.

Thanks for helping me understand le logic of "saving"/registring colormaps
and pointing me to direction to create my own colormap collection and a
simple way to use them
