Waveform Chart stop/start on Key Command

[Marshman]

Hey all,

I have a VI with a waveform chart and I want to be able to do a couple of things with it.  Currently I have the chart to start when I press the "O" key.  But this is where I get stuck.  I then need the graph to stop (pause) on a key stroke without losing the data.  I also need a keystroke set up to reset the graph to a blank screen.  Any help would be great.

See attached VI.

Here you go.

Never add a function with an indeterminate length of completion in your UI loop.

Thanks for the post and updated VI. I see that you have the clear history as the outcome from pressing "23" which i do need need!

Additionally, How can I program another key to just pause the graph, without clearing the data.  I want to be able to run the graph as long as the user wants and then extract the data.

Currently if you press any Key besides the O or the I key it will pause. Do you need it to be a specific Key?

[Marshman]

Yes, I would like it to be a specific key if possible.

You answered my initial question fully so I will give you the solution.

Furthermore, I want to implement several of these in a tab control - See VI.  It doesn't seem to work. Could you help with that?
