Matplotlib scale

[julienhofmann]

Hi everyone,


I've created a code to run a 2D mapping using matplotlib from a .csv file.
I've tried to set the maximum color (red) of the scale as 80% of the maximum value and not as the maximum value of my .csv file.
Does someone know how to modify that?
I've tried different solution but it doesn't work.

Thanks
