Re: regression plot

Hi Lin,

I should have noticed this before.

You are setting xy* resources for the gsn_add_polyline functions.
The gsn_add_polyxxxx functions are not considered XY plots; they
are simply routines for adding things like markers, lines,
and polygons to an *existing* plot.

Instead of using xy resources, then, you want to use gs resources:

       resPL1_at_gsLineDashPattern = 18 ; dash line
       resPL1_at_gsLineThicknessF = 3
       resPL1_at_xgsineColor ="red"

       resPL2 = True
       resPL2_at_gsLineDashPattern = 0 ; solid line
       resPL2_at_gsLineThicknessF = 3
       resPL2_at_gsLineColor ="black"

Also, there is no dash pattern 18. They only go up to 16:

You can add your own dash patterns via NhlNewDashPattern:

   http://www.ncl.ucar.edu/Document/Functions/Built-in/NhlNewDashPattern.shtml

and these will be added temporarily to the current table of dash
patterns, starting with pattern 17.
