How to display data collected in main vi to indicators in another vi

[ygupta]

Hi,

I am collecting data using NI 6251 USB DAQ in the main vi but as i have too many controls and indicators on the main vi front panel. so i want to display the indicators(graphs) in another vi. i also want the vi with the graphs to open automatically. Does any one know how i can do this? I would really appreciate any help.

Thanks,

ygupta

This sort of question has come up many times. If you do a search for "popup VI" you will find many hits. Examples are also included with LabVIEW. As for passing data there are a multitude of ways to do this. You can use control references, queues, action engines, ...

Hi Shrek,

The graphs right now are in a while loop and display the data that is acquired continuously. So I want them to be visible when the acquisition start therefore i want the vi with the graphs to open automatically at that point. i think i have touse a sub vi to do this but i dont know how to connect the graphs in the subvi with daqmx read blocks in the main vi. as i have not used sub vis before.

Have you gone through the LabVIEW tutorials? SubVI are a core concept. To learn more about LabVIEW it is recommended that you go through the tutorial(s) and look over the material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.

I would also suggest using a tab control to seperate your graphs and controls.  Then you don't have to worry about popup windows.

Good Luck
