setting region with curvilinear coords
Suppose I have a variable defined on curvilinear coords. I can display
this using the 3-argument version of shade, for instance:
shade my_data,x_grid,y_grid
where x_grid and y_grid give the lon and lat coords.
My question is: can I set the region *based on x_grid and y_grid*,
not i or j?
I want to be able to limit the shaded plot to a rectangular range in lat/lon
space which bears no direct correspondence to the i/j grid coords of my
data.
I could probably do this by regridding, but perhaps there is a more
direct route?
I'm rather new to ferret, so my apologies if this is obvious. I've looked
through documentation and the mail archives, but can't find the
answer.
Cheers,
- Andrew
