Thanks Chris,
I'll give it a shot :) I sent an email to the techsupport@ittvis.com
address earlier today about this, so you might want to check on that
so that the same problem doesn't get logged twice.
I appreciate your help,
Jeff

Hi Jeff,
This is indeed a bug. It looks like all of the other keywords work,
just not XTICKVALUES. I've logged a bug, and it will be fixed in the
next IDL version.
If you are feeling brave, and you desperately need a fix, you can
modify lib/itools/components/idlitvisaxis__define.pro. At the very end
of the ::SetProperty method, add the following line of code:
if (N_ELEMENTS(_extra) gt 0) then self._oAxis->SetProperty,
_EXTRA=_extra
This is not the exact fix that I will put into the production code,
but it will get you up & running.

*sigh* I was afraid this was a bug....guess I'll report it.
Thanks,

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
