Hi John,

As long as you have called GraphicsModeControl's setScaleEnable(true)
you should get an axis scale for every ScalarMap mapping a RealType to
an Axis. e.g.

  display.getGraphicsModeControl().setScaleEnable(true); 
  display.addMap(new ScalarMap(a, Display.XAxis));
  display.addMap(new ScalarMap(b, Display.XAxis));

should give you a scale for a and b along the x axis, unless I am
missing something.

I ran into the opposite promblem: how do you keep only one of these
scales? My solution was to map to XAxisOffset to avoid the scale.

Hope this helps,
Doug
