I'm afraid the only solution I know of is for you to switch to HP's
Drawing/Charting Gallery package.  The package (and I'm assuming the
others don't) provide for "shielding" where you can do what is
effectively hidden line removal when plotting.  Be warned tho' that
there is a small time/memory usage penalty.
