Originally, the sample locations in Sets were all doubles,
but that used so much memory that we changed them to floats.
We added the class Gridded1DDoubleSet to support unevenly
spaced samplings of RealType.Time, which need doubles to encode
dates and times in a single number with adequate resolution.
It would be possible to add a class Irregular3DDoubleSet, but
it would take some real work.
If your data don't really need double precision, converting
doubles to floats will be a lot easier than creating a new
class Irregular3DDoubleSet.

If you've done:
ScalarMap xmap = new ScalarMap(x, Display.XAxis);
xmap.setRange(-1.0, 1.0);
then later you can do:
xmap.setRange(-1000.0, 1000.0);
and that should change the axis scale.
Cheers,
Bill
