Graphics: NCL – Example

wrf_Overlay.ncl

Example script illustrating how to overlay.

In this script note:

1. The use of gsn_define_colormap to overwrite the colormap set in .hluresfile;
2. To overlay, set FramePlot to .False. when using the function wrf_map_overlays.
   Then draw a line with the function gsn_polyline, circles with the function gsn_polymarker,
   and finally text with the function gsn_text before advancing the frame manually (frame(wks)).
