Sorry, I took an hour to take a walk in the sunshine. First
time I've been out of my cell for several months. :-)

Well, first of all, OPLOTERR is brain dead. So,
I can't do much about that. (I assume this is what
you mean by OPLOTERROR?)

But this works:

!P.Background = cgColor('white', 254)
!P.Color = cgColor('black', 253)
x = indgen(101)
y = cgDemoData(1)
errors = randomu(-3L, 101)*4
cgPlot, x, y
oploterr, x, y, errors

Is that what you mean?

Cheers,

David
