Do you mean the color passed to Scalarmap.setScaleColor(),
which determines the color of the axis scale display?  They
do not have to have different colors.

How are you enabling axis scales?  If you call:


you should see axis scales for each ScalarMap to XAxis,
YAxis and ZAxis.  If you are calling:


for any particular Scalarmaps, that will disable their
axis scales.  See visad/examples/ for an
example of displaying axis scales for only some of the

If you think you've found a bug in VisAD, please send me
your code and enough data to run it.
