I am able to reliably display text summaries of ranges as a 'plot title' and those 'idlgrtext' summaries have yet to behave poorly, but the tick text behaviour is really unacceptable.

I suppose another possibility is that OpenGL is to blame. I'd be curious
to know if MatLab or R has the same problems with this data.

But, there can't be too many people here who wouldn't dismiss those
kinds of numbers as "essentially zero." What have the folks at ExelisVis
had to say?

Cheers,
