[ncl-talk] r,theta (radar) plotting

Sat Jul 13 02:41:51 MDT 2019

I tried to plot in the Cartesian coordinate, so I made change code from
line 69 to 73 on rgrid2geocircle function. I am getting the following
warning.

warning:ContourPlotInitialize: no valid values in scalar field; ContourPlot
not possible:[errno=1101]

Kind suggestions would be appreciated.
