Hi Thomas,

Display.LineStyle and Display.LineWidth can only be used in
ConstantMaps, not in ScalarMaps. Hence you have to divides
lines with different styles or widths into different Data
objects, passing appropriate ConstantMap[] arrays to the
addReference() calls that link the different Data to the
Display.

to do this draw some graphics (text, lines, images, etc) in the
space of your RealTypes mapped to XAxis and YAxis, centered in
the range of your XAxis values and less than your lowest YAxis
values. Make sure to explicitly call setRange() on your ScalarMap
to YAxis, so the auto-scaling doesn't put your graphics above
the bottom of the box. You'll probably need to experiment a bit
to get your graphics placed where you want them. See Section
2.2 of Ugo's VisAD Tutorial for help with setRange().

Good luck,
Bill
