Hi Bernd,
Nice image. In order to replace the text with weather
symbols you'll need to replace the ScalarMap to
Display.Text with a ScalarMap to Display.Shape. See
Test46.java and Test47.java in visad/examples for
simple examples of using Shape. It is also discussed
in sections 4.3.12 and 4.7 of the VisAD Developer's
Guide. You'll pass an array of VisADGeometryArrays for
your weather symbols (from wmo.jhf) to the
setShapes() method of your ShapeControl, and pass a
1-D Set to its setShapeSet() method - this Set defines
how your numerical iso values are sampled to discrete
weather symbols.
I have CC'ed the VisAD mailing list, since all technical
questions should go to the list rather than just to me.
Good luck,
Bill
