[ncl-talk] problem with ShadeGeLeContour

[Mary Haley]

Hi Debasish,

No worries on posting to me directly.  Usually with NCAR visitors and
employees I don't ask this, so my apologies there. However, I like to see
messages go back to ncl-talk if possible so other folks can benefit from
the answer.

>From your script I was able to see what the problem was.  It looks like the
code that shades for the middle shading values is incorrectly assuming that
you have 2 or more contour levels that fall in this range.

This bug was inadvertently fixed in V6.2.1, in the process of enhancing the
function for other purposes.

You can try the fix on yellowstone/geyser by loading a *test* 6.2.1 version
via the "module" command:

module swap intel gnu
module load ncl/6.2.1

Let me know if this doesn't fix your problem.

Please be careful with this version because it is in heavy test mode and
can get updated at any moment. We hope to release this version in the next
2 weeks.

--Mary
