Use the RendererControl.setBackgroundColor() method.  You can
call display.getDisplayRenderer().getRendererControl() to get 
the RendererControl.  Test53 in the examples shows this.

See the visad.AxisScale class.  There are several methods to
change the properties of the AxisScale.  In particular for
your question:

   setMajorTickSpacing()
   setMinorTickSpacing()
   createStandardLabels()
   setLabelTable()

methods should help.  See Test26 in the examples.
