CONTOUR and automatic gridding of irregularly spaced data [message #85023]

Hi all,

IDL 8.2.3 provides automatic gridding of irregularly spaced data with
the CONTOUR function. Great, I thought in hope to get rid of my CONTOUR
plots in direct graphics.

But when I use a CONTOUR function plot combined with a 'Mollweide' MAP
projection and CENTER_LONGITUDE=nonzero_value the automatic gridding
yields a gap between the -180 and +180 degrees longitudes.
The gap exists even though I have used GRID_UNITS='degrees' which should
cause the use of the SPHERE keyword as it is stated in the documentation
of the CONTOUR function.

The only way to avoid this is manually invoking the gridding routines.

Did I do something wrong?
Or can someone confirm this behaviour?

Thanks and regards

Karlo
