Hey, 
I'm creating an application which stores measurements (e.g. temperature) to textfiles (*.txt). I've created a vi wich is able to read these files and shows the information in a WaveFormChart. 
I would like to use some kind of button within my main panel (interface.vi) to show this vi, but I don't know how to do this. 
Could you help me with this problem, please 
Kind regards
