Sir,
You defame me most unjustly! :-(
After 14 years with IDL, I can speak Yank with the best of them.
Y'all have a Nice Day now.

Hi,
I think you have omitted the underscore in the BOX_AXES keyword. The
BOXAXES keyword, which doesn't exist is quietly ignored since the
MAP_GRID routine accepts _EXTRA keywords. This has always been a sore
spot for me... note that MAP_GRID accepts the keyword NO_GRID but FLTARR
accepts the keyword NOZERO. Bah!
Cheers,
Ben
PS And don't get Andrew Cool started on the keyword COLO(U)R!
