The trick is to calculate the values in a worksheet range parallel to the
series values, then use these calculations as the source for your custom
error bar values.

I want to have error bars added to each bar, based on that bar's standard
error.
The only think that I can find excel letting me to do is add some number
to
all bars of a series.

is there a way to add calculated error bars for each individual bar in a
graph?
