[ncl-talk] Add_Polyline Problem

[Jeremy Berman]

Hi Kerwyn,

Thanks for sending the code. Try increasing the thickness of the cross section line, such as setting plres at gsLineThicknessF = 20.0. I think the problem is that the thickness value you set (2.0) is too low to see on the plot.

Best,
Jeremy
