In your case the errors are so small that even if we can draw the error
bars correctly, they would be completely overwhelmed by the size of the
symbol you are using to represent the point itself. Even if you plot a
line of data with the error lines above and below, it all appears as a
single line on the plot. Essentially, there is no difference between the
data and the data plus or minus the extremely small error.

Cheers,

David

P.S. See the announcement in this group for new error bar handling in
Coyote Graphics routines.
