pressure/height vs lon

Hi there.

I am creating some contour + vector pressure/height plots using

gsn_csm_pres_hgt_vector

and am wondering 2 things

1. is there a way to change the scale on the height axis?

eg. I am only looking at the bottom 500mb of the atmosphere so would
like the height scale to be every 1 or 2 km (instead of 4km)

2. is there a way to get only every 3rd or 4th vector to plot?

I tried using the resources
res@vfXCStartV = 0
res@vfXCEndV = dimsizes(data(0,0,:))-1
res@vfYCStartV = 0
res@vfYCEndV = dimsizes(data(0,:,0))-1

and then specifying
  plot(i) =
gsn_csm_pres_hgt_vector(wks,data(i,:,:),hwind(i,:,::4),omg(i,:,::4),res)

but when I do this no vectors are plotted at all?

thanks,
jason
