[ncl-talk] gsn_contour_shade

[Laura Fowler]

Hi Adam:

Thanks for your help. It did work after switching to gsn_csm_contour. I
followed your suggestion and added separate resources for plot2 to remove
the "mp" warning messages.

Despite adding the following lines:

ores at cnFillOn      = False

ores at cnLinesOn     = False

ores at cnLevelFlags  = "NoLine"

ores at cnInfoLabelOn = False

to my second (ores) set of ressources, I still get labels attached to the
shading. Which additional option do I need to add to remove those extra
labels so that the output looks like the one in overlay.ncl?

Many thanks,
Laura
