How do I add a vertical cursor to a 2-plot xy graph?

[Brian_Beal]

I have a 2-plot xy graph, and I would like to add a vertical cursor that can be dragged to any x position, and have the 2 y values displayed.  How do I do this?

If you want to interpolate between points, then you can use something like the attachment. If you only want to display y values that actually exist in the two separate arrays, you would use Cursor.Index, Index Array, and set the cursor to snap to plot.

Thanks, Dennis.  I was hoping for something inherent, but this will work fine.

OK, my problem is deeper than reading cursor position.  My cursor disappears when the VI is first run, never to appear again.  I have the X-axis set up for absolute time, and I think that might have something to do with it.

Get the minimum value of your X array and write that value into Cursor.PosX property node.
