You can change the interval, but can't add more labels at the current time. I'm
working on that enhancement, but don't expect to get it completed before the end
of March. The enhancements will be made to the AxisScale class which is the
controling class for the look of a Scale. Recent enhancements allow you to set
the major and minor tick spacing. So in your example, if you only wanted ticks
at 0, .5, and 1.0, you could do something like:
myScalarMap.getAxisScale().setMajorTickSpacing(.5);
This would still only have labels at 0 and 1.0. You could also do something
like:
AxisScale scale = myScalarMap.getAxisScale();
scale.setMajorTickSpacing(1.0);
scale.setMinorTickSpacing(.25);
which would give you large ticks at 0 and 1 and smaller ticks at .25, .5 and
.75.
My goal for adding more labels is to use a design similar to JSlider where you
can set the specific labels you want using a Hashtable of values. This would
allow for Text labels as well as numeric labels.
If you have any suggestions on this implementation, please send them
along.
