Re: map tick mark problem

Hi Nicole,

It's hard to debug a program this big without being able to run it, because I can't easily tell what graphical resources are being set.

I'm not sure why you are seeing the tick marks show up for the contour plot, but perhaps you can try turning the tickmarks off for the contour plot case.

Inside set_resnarr, or any place where you are setting "resnarr" values, add:

  resnarr@pmTickMarkDisplayMode = "Never"

Generally, I recommend people *not* use gsn_csm_vector_scalar_map, and instead use a combination of gsn_csm_contour_map and gsn_csm_vector, and then use "overlay" to overlay the vectors on top of the map.

For example, instead of:

    plotseasonmap(nruns+1) = gsn_csm_vector_scalar_map(wsseasonmap,vectmap(0,:,:),vectmap(1,:,:),narrseasonmap,resnarr)

you could try something like this:

    plotseasonmap(nruns+1) = gsn_csm_contour_map(wsseasonmap,narrseasonmap,resfill)

    vectorsonly(nruns+1) = gsn_csm_vector(wsseasonmap,vectmap(0,:,:),vectmap(1,:,:),resvect)

    overlay(plotseasonmap(nruns+1), vectorsonly(nruns+1))

"resfill" and "resvect" would come from splitting up "resnarr" into contour/map resources for resfill, and just vector resources for rectvect.

See examples "lcnative_5.ncl" and "lcnative_overlay_5.ncl" at:
