Re: Question about wrf_vector

Hi Hui,

By default, the wrf_vector, wrf_contour templates don't draw the
plot. They are intended to be used in conjunction with wrf_map_overlays,
which *does* draw.

However, you can force the draw (and page/frame advance) with:

   res_at_gsnDraw = True
   res_at_gsnFrame = True

It looks like the documentation page for this is incorrect. I'll
double-check it.
