2D surface plot : color scale adjustments

[Damien]

Hello,
I would like also to plot separately several 2D mesh surfaces with the same
color scale using the jetcolormap. I tried several color options without
success. Need also plotlib for that ? Here is a simple example :

X = [
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.  
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.  
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.  
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.  
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.  
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.  
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.  
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.  
    1.    1.25    1.5    1.75    2.    2.25    2.5    2.75    3.

ee.color_flag = 3;
drawnow;
