ok the reference works after the loop in the subvi is completed but what if the calling vi needs to display the real time data at the instant the subvi has it, can this be done?
Your entire program makes very little sense. Since your graph is set to lines and you are graphing only a sigle point, you'll never see any data anyway, right?
Somehow, it would make more sense to e.g. build the graph with successively larger portions of the arrays as e.g. in the attached image.
