how to call single vi in multiple windows

[TRanjith]

i have one single graph accessing data through global variable in a file grpah.vi.  Graph runs in a while loop.

In my main vi, i have 4 sub panels. pressing respective buttons should display graphs in respective sub panels using graph.vi . I am using event structures for button clicks.

Can some one guide me to implement the program.

Hi Ranjith,

you can one vi only show ones in a subpanel. Use the invoke node to add and remove the sub vi to/from your sub panels. Before you add it to a new sub panel you have to remove it from the other one. Use a shiftregister to store where it was last inserted.

Hope it helps.

Hi Mike,

Thanks for the quick reply.

Okay. let me know weather i can do defferently.

I have one button "Open in new window" in my main vi. pressing that i want to call graph.vi in multiple windows based on number of times he pressess the button.

Again graps run in while loop accessing global data.

How can do this?

Hi Ranjth,

if you need your graph.vi multiple times, i recommend to create a vi template. If you use it later, you will get a new instance for each call. If you make it in this way, then you can show it at the same time in all sub panels.

Hey Ranjith,

I found an example called Occurences2.zip from Re: Community Nugget 1/29/2007. It should help you understand how to call a predetermined amount of VIs.

The only thing is that you'll have to specify a predetermined number of VIs beforehand.

Hopefully this helps!!
