Calculate from graph cursor data

[markrose]

I need to calculate from cursor data in a grpah that has been read from a file and displayed. Specifically, I want to position locked-on-trace cursors and calculate the delta-time or delta-voltage from their positions like one would with a standard scope. Attached is a file of the trace to read, 2 channels, Cursors would be on either ch-1 or 2. Simple read VI attached.

Mark,
I think you can do what you want by using a property node for the graph. I use it all the time. It can tell you X and Y values. If this sounds close let me know and I will try to whip up an example for you.

Here's a very simple example. You just have to use the graph's property node to get the cursor position. If you know the sample rate, you can fine tune it to display actual time.

See if this is what you need

Sean,

Thank you very much for a quick and excellent response!

Dennis,

Thank you, also, for your excellent response. The manual was not definitive on the property node's use and practical application, at least for me. You and Sean have cleared it up and I appreciate it very much.
