Mark, The mp_scripts are sensitive to the region you've selected. To be on the safe side I'd include the set regioncommands in your second plot as well. -- Jon Mark.Collier@csiro.au wrote: Hi, In the following script I see the correct result in the 2nd window (which is approximately centered at 140,-15 to compare) but the wrong result in the 1st window. The field does not seem to be plotted at the meridian that I specify, however, the land overlay looks in the right spot. Is there something obviously wrong with my syntax? Interestingly it plot o.k. (for a split second) but then a second fill overlays the result almost immediately.
