You may be able to adjust the margin by applying a scale
to the projection matrix. See the rotate() method of
visad/examples/Test58.java for an example, except that
you want to call make_matrix without rotation but with
scale other than 1.0:
make_matrix(0.0, 0.0, 0.0, scale, 0.0, 0.0, 0.0)
You'll need to experiment with various scale values to
find one that works for you.
