MinMax labelbar

 Dear all,

I would like to plot a seasonal map of sea surface temperature over Indonesia.
The was no problem in my routine, and the results look OK. However the plot reproduced a difference range label bar for every period (what I want is between 20-30 C). Although I had defined the contour level "cnMinLevelValF and cnMaxlevelValF", but the change does not appear.
Any suggestion (in which part should I modify) would be very apreciated. The routine to plot is attached.

Thank you

Best, Siswanto
