projecting in nsp

Thanks to all in solving my last problem.

I have a regular spaced lat lon grid that I plot using mproj = latlon and I can control the lat lon that I view by setting the lat lon but I now want to project on to nsp but be able to control how much I see.  for example I only want to see lat north of 65N.

I can project the entire data set on to nsp but how do I tell it to only show/plot north of a certain lat?

Thanks

John,

I'd use a grads script to return the XY coordinates of the sides of the
plot using "q gxinfo", then use "draw string" to plot labels relative to
the 4 corners.  Include something like this to  get the X and Y values
of the sides of the plots:

'q gxinfo'
xvalues=sublin(result,3)
yvalues=sublin(result,4)
* xl = plot starts xl inches from left
* xr = plot ends xr inches from left
* yb = plot starts yb inches from bottom
* yt = plot ends yt inches from bottom
xl=subwrd(xvalues,4)
xr=subwrd(xvalues,6)
yb=subwrd(yvalues,4)
yt=subwrd(yvalues,6)


The lower left corner of the plot would be at "xl" "yb". Upper left at
"xl" "yt". Upper right "xr" "yt". Lower right "xr" "yb".
