Don't know anything about Origin, but for an add-in check the Plot
Manager program available from my web site. For a non-programmatic
solution, check the one of Stephen Bullen's examples at
www.bmsltd.co.uk, specifically the Excel | Charting section.

Hi
Does anyone know of a good Excel graphing add-in. I need
to be able to define a line equation and then apply it to
the graph. Similar to Origin, if anyone is familiar with
that.
Thanks
Jo
