Graphics: NCL – Example

wrf_panel1.ncl

Example script illustrating how create a panel plot.

In this script note:

1. The use of gsn_define_colormap to overwrite the colormap set in .hluresfile;
2. To prepare the individual plots, NoHeaderFooter and lbLabelBarOn are set off for each plot;
3. To panel, set PanelPlot to True when using the function wrf_map_overlay;
4. Setting CommonTitle to True and PlotTitle to the current time,
   will overwrite ALL field information for each plot with the current time.
   These are wrf_map_overlays resources;
5. Then use gsn_panel to panel the 4 plots generated.
   gsnPanelLabelBar is used to generate a single label bar for the 4 plots.
   txString is used to generate a single header for the 4 plots.
6. The middle picture below was created with wrf_panel1-1.ncl.
   In this script we paneled an odd number of plots, the last plot is centered.
7. The right-hand picture below was created with wrf_panel1-2.ncl.
   In this script we paneled an odd number of plots, the last plot is inline.
