Dear NCL-ers.
Apologies if you receive this twice.
I am trying to make a complex panel plot displaying 2 variables (temp. and precip. biases) using different color tables. My script mimics code in http://ncl.ucar.edu/Applications/Scripts/panel_12.ncl and is *Ualmost* right. The LHS column (temp.) and RHS column (precip.) both look fine and use their different color tables, and have seperate labelbars beneath each column. However, the issue I cannot solve is that the colors of the colorbar only come from the color table for precip -- the RHS column which was drawn last.
How can I insert the correct label bar for the temperature column? I really don't want to have precip and temperature differences use the same color table. Nor do I want to split into two seperate plots.
The misbehaving plot is attached, and relevant code snippet is below.
Many thanks,
Maurice
