How to enter constants into Labview that will affect the graph?

[jenifr2g@cox.net]

How do you enter constants into Labview in which x and y would be dependent on them? Ex. Say I am creating a graph of voltage vs time and I want to have constants such as trigger level (such as wanting my graph to start recording data when it reaches 20 volts and stop recording after 20 volts). I would also want to have a time interval as a constant. I have no clue how to do this in labview so I am looking for some kind of help. Thanks

You would just make the values write to an array of x vs y.
The values would only write if some boolean was true (such as voltage > 20)

Then cluster the x and y and send the cluster to a graph.

Thank you, sorry if the question was on the dumb side. But i am very new to this program and before Christmas break I have to set something up for my job. I have been reading a lot about Labview and have done some tutorials, but nothing I have read has mentioned any of that and I am getting very annoyed with trying to figure things out by myself. Some of the stuff doesn't make any sense to me.

What I was explaining before was correct, however disregard the image.

Here is the code you could use instead.

Ok, thanks.

Where do you find the I32 constant? I can't seem to find it anywhere

[jenifr2g@cox.net]

Nevermind, sorry, I feel really dumb right now. I just figured it out. Thanks for your help again 😃

Does anyone know if once you have the code given above how you could incorporate it to give a table of the graph?

After the build array function, right click on the output side, and click "create indicator".

This will put an array (table) on your front panel.
