Combo Box (Form Control) With Macro On A Graph Sheet

Guys, I have another interesting challenge. I have a sheet, which is a graph (e.g. when you select a graph, right click > MOVE TO NEW SHEET). On that graph-sheet I need to add a "Combo Box (Form Control)" and attach a separate macro to each of the list points in the box. Meaning, when I choose entry one one a list, macro 1 is run, when I choose entry 2 on a list, macro 2 is run, etc.
I dug up that this IS possible using an ActiveX object ["Combo Box (ActiveX Control)"]. However, since the whole graph is a separate sheet, I can't put (area s grayed out) a "Combo Box (ActiveX Control)" object onto it and hence I can't use it.

So my questions are:
- Is it possible to somehow put Combo Box (ActiveX Control) onto a such a graph-sheet?
- Is it possible to realise what I need via Combo Box (Form Control) object somehow? (how to attach a separate macro to each list entry)

Again, the punchline of what I need to do is: with selection of each entry from a list of my Combo Box (Form Control)/Combo Box (ActiveX Control) a separate macro should run, e.g. with 10 points in the list 10 macro will be assigned, with each macro running when a corresponding list point is selected.



Any help would be much appreciated!
