[ncl-talk] filled in predefined markers

[Mary Haley]

Thanks Vandhna, for answering this question.

Rabah, as an FYI, you can see all the font tables at:

http://www.ncl.ucar.edu/Document/Graphics/font_tables.shtml

If you click on any row of this font table, you will see all the characters
for that table.  Any character from any of our font tables can be used with
NhlNewMarker as Vandhna pointed out.

My favorite font tables to use for markers are:

http://www.ncl.ucar.edu/Document/Graphics/Images/font37.png

I like them because they contain some filled markers, which look better
than the hollow ones.

To see some examples of using NhlNewMarker, see:
