Floating numerical display of 1D waveform Y data

[bassinbc]

Is there a simple way to take the Y data from each 1D array of Waveform data and display it to a floating numeric display on the front panel

[jwscs]

yes there is

[McQuillan]

Yes, you can use the 'Get Waveform Components' function to extract the Y data. This will give you an array of doubles. You can then use an Index Array function to look at individual points and view them on your front panel.

I want each display to be floating while the vi is running.

Do you mean you want the graph to be floating?  Like "independent of any containing window" kind of floating?

[bassinbc]

No, just have a numeric display for each Y data in the Waveform array. Then those numeric displays would be user movable. This would be independent of the graph.

[jwscs]

there is no simple way to let the user move controls/indicators at runtime.

you could do that programmatically, but it is more involved.

Hi bassinbc,

just have a numeric display for each Y data in the Waveform array.

This has been shown above in the snippets.

Then those numeric displays would be user movable.

This is a completely different problem: let the user move an indicator on the frontpanel!

You can use the event structure to track mouse moves, mouse clicks, and context menu actions of your user. Use all that information to change the position of the indicator on the panel/pane (using its properties)…

I know how to get the Y-Data. The second problem as you called it has been a problem. I found this UI Panel example sometime back and I will dig into how to use this. Just more complicated than I wanted.

To be fair, I think that is what the OP meant by "floating" in the subject line.
