Dear Chris,
I believe I've narrowed it down. Error bars erroneously obscure some overlying plot
symbols provided that two conditions are met:
1. at least two data sets are plotted in the same plot using the OVER keyword and
2. the primary plot is resized using the POSITION keyword.
In this case, some of the plot symbols in the secondary plot will be obscured,
not the primary.
The following example is not exactly minimal, but reproducibly exercises the bug.
Set bug = 0 to turn the bug off.
Thanks for looking into this. TTFN,
David
