[ncl-talk] How make these plots with NCL?

[Dennis Shea]

Hi Markus

Mimic F3.large.png:

The attached script uses bogus data. Likely NCL graphics experts can
improve it. In fact, I'm not sure why the tick mark grdd outlines for the
t-Value grid are not working.

One example use a cylindrical projection ... the other a Robinson.

The background figure (?vegetation?) can, of course, be done via NCL:
    *http://www.ncl.ucar.edu/Applications/classification.shtml*

The triangle .... I am not sure what to make of it

My *speculation *is that the was an image 'captured' via some external
tool. Subsequently, it was labeled and the resulting graphic overlaid onto
the vegetation plot.

I had an NCL script that generated the locations for a 'triangle grid'.
Using that, I added an example that uses the sfXArray, sfYArray and
the trGridType
resources to contour triangular data.

*http://www.ncl.ucar.edu/Applications/polyg.shtml
<http://www.ncl.ucar.edu/Applications/polyg.shtml>*
Example 28

The example shows a classic triangle. However, the vertices can be any
three locations.

Hope this is of some help!
