multipexor sub-vi

[straight]

I'm trying to create a sub-vi that can route dynamic data, at run-time, from several sources to an XY-chart. I was hopeing to be able to let the user select the source from a menu. My proble is (besides my lack of experiance with LV) when ever my main program calls the sub-vi all data resets to 0 before transfering the signal.

Hi straight,

It sounds like you want to have the user select what data gets plotted on an XY Graph.  Are you using a case structure?  It would be helpful if you could post a picture of your block diagram or a snippet of your code, and we can make suggestions on why you aren't seeing what you expect.  Fill us in on some more details on your current architecture, and we can try our best to help.  Have a great day!
