Updating graphs between two VIs

[VEEDAY]

I have a VI (event-structure based) that generates and displays waveform chart. Due to lack of space on the main VI, I want the graph to be displayed onto another VI. Could anyone please help me with an example, how to implement this? 

My attempt doesnot update the graph using sub-VI.

Thanks

You will get more help if you post your code for others to look at. That way we feel we are helping and not doing.

A simple example is attached along this email. The subVI is invoked from the MainVI which attempts to zoom the graph, but it does not continuously update the graph data as in MainVI. Thanks
