[ncl-talk] Using vp resources for panelling different sized WRF contour plots

[Mary Haley]

Hi Tabish,

I haven't tried this with wrf_map_overlays, but I think if you want to
change the width and height, you need to do it using the second resource
list associated with wrf_map_overlays:

mpres = True
mpres at vpHeightF = vph
plot(1) = wrf_map_overlays(c,wks,(/contour_d04/),pltres,mpres)

If that doesn't work, then you could try setting the height after the plot
is created:

plot(1) = wrf_map_overlays(c,wks,(/contour_d04/),pltres,False)
setvalues plot(1)
  "vpHeightF" : vph
end setvalues

If that still doesn't work, then it would help if you could provide your
data file, which you can use our ftp for, if the file is not too large.
You can email me this information offline if you don't want to email the
whole group.
