Hi M. Katz,
Perhaps you could do something like this:
IDL> oSurface = obj_new('IDLgrSurface', dist(30), style=2, color=[255,0,0])
IDL> oAxis0 = obj_new('IDLgrAxis', 0)
IDL> oAxis1 = obj_new('IDLgrAxis', 1)
IDL> oAxis2 = obj_new('IDLgrAxis', 2, location=[0,1])
IDL> oWindow = obj_new('IDLgrWindow', dimensions=[400,400])
IDL> oView = obj_new('IDLexObjView', [oAxis0, oAxis1, oAxis2, oSurface])
IDL> oView->Normalize, oWindow, /adjust_axes
IDL> xobjview, oView, xsize=400, ysize=400
The ability of xobjview to draw IDLexObjView objects is undocumented. The
oView->Normalize, /adjust_axes is undocumented too.

There is a diagram of some of the IDLex classes at www.paulsorenson.com
under the link "XOBJVIEW: Under the Hood" .
