Displaying a multiplot chart, I need to have the value displayed as the mouse is moved over the waveform.

I've seen this on software that I believe is LabVIEW. As the mouse pointer is moved over any waveform on the chart, a "tip" is displayed with the value of the graph at that particular point. I NEED this!

Hi,
actually I don't know easy way to create such a tip in LabView.
But you can use free cursor to do something like that. You can show the cursor legend and create a free cursor. Now while the cursor is moving over the graph its coordinates will be shown in cursor legend.

May be this will be useful for you.
Good luck.

I'm not sure if this was LV you were seeing, but with a little
programming, I think you can do it, or something similar. If using
LV6.1 or later, you can get notified of the mouse position over the
graph. With these pixel positions, you can map it back to time and
value and write that to the graph's tip string property or wherever else
you want to place it.

I believe there are some VIs on devzone that will take a reference to a
graph control and a pixel location and return the scale values for that
pixel. You might try a search and see what turns up.
