map_set - 8-element limit [message #12427]

Hello group...

I'm having trouble (idl 5.1; alpha) with map_set limits for 8-element
vectors.

map_set,lim=[-65,-180, -65,-90, -65,0, -65,90],/grid,/cont,/iso,/ster,-90

ought to work (all pts along 65 S, regularly spaced in longitude)
since its a perfectly good square in physical space coordinates.

But it doesn't - I get just a single horizontal line and a divide-by-zero.

I had a quick look at map_set and
just got more confused - it appears to do some convert_coord stuff to work
out what limits to use - but how can it do this *before* the map xform is
established? Maybe I read it wrong.

Whats up?

- William
