Is there any way to atttach a callout to a point in a chart series?

[THOMAS CONLON]

I use the drawing toolbar, and put a callout into a chart, with the point of
the callout touching a pointon the chart. But, if the chart re-scales, then
the callout no longer points to the same series point that it used to. Is
there a way to anchor that callout to a particular point in a chart series,
so that the chart can rescale and the callout still refers to the same
point?
Thank you.
