This seems to be a bug. I added Vertical error bars and got both. I clicked
on one of the Horizontal and remove all with the Delete key.
Let's see if Jon Peltier has this in his list of know charting bugs.
best wishes

when using excel 2007, in scatter charts. I can't seem to specify only
y-axis (vertical) error bars. The dialogue box states vertical error
bars,
but horizontal ones are also added? Any hints?
