We make a lot of contour plots and wind vector plots on various map bases.
One of our users works with arctic-only data, and routinely makes plots on
a polar stereographic projection of the Arctic region (60N to NP).
An app written for IDL 3.5.1 uses the commands
MAP_SET, 90., 0., -90., /STEREO, LIMIT=[60., -180., 90., 180]
to set this projection up. Then the plot is drawn and finally we do
MAP_CONTINENTS
MAP_GRID
to get the map outline overlayed on the plot.
We just installed IDL 3.6.1 and this code no longer seems to work.
Now we get total garbage when plotting, and even the extremely simple
command sequence
MAP_SET, 90., 0., -90., /STEREO, LIMIT=[60., -180., 90., 180]
MAP_GRID
produces several screensful of error messages (Floating overflow) from
MAP_GRID in map_set.pro. Then a couple of random lines appear on the plot
frame, and we're back to the IDL plot.
Has anybody else reported this problem? Is there a quick fix? If you
type the two lines of code above in your implementation, do you get the
same errors?
Please respond via email or post. I will be glad to summarize.
Thanks in advance!
