This looks like a bug to me. The iPlot documentation indicates
you ought to be able to pass along XTICKVALUES, for example,
but in fact the iPlot program does nothing with them.

The reason I think this is a bug, is that I have no problem
creating irregular tick spacing and labeling in my XPLOT
program, which is an object graphics program. I simply
create the axis like this:

xAxis1 = Obj_New("IDLgrAxis", 0, Color=[255,255,0], Ticklen=0.025, $
Minor=4, Range=[0,10], Title=xtitle, $
TickValues=[0.0,0.8,1.5,2.0,3.5,4.3,5.8,6.5,7.2,8.8,10.0], $
Location=[1000, position[1] ,0], Exact=exact[0])

Cheers,

David
