synchronize cursor and mouse

[CyGa]

I would like to synchronize the mouse and the cursor of my graph. When I click on a waveform graph, I would like the cursor to come at the position clicked.
Is it possile?

Thank you

You could use an event structure to detect the mouse click.  Then use the Coords element to set the Cursor.Posistion property fo the waveform graph.  Unforntunately, Coords is measured in pixels on the pane and Cursor.Position reference the X and Y scale of the graph, so some amount of conversion is necessary to get the cursor to the right spot.

Personally, I use the cursor button on the graph palette.

Actually, the conversion is straight forward, since there is a little known function, as invoke node, that do the conversion for you. Beware, the graph reacts to any click, even on the cursor button, and you need to use the Map to XY boolean output.

All this is demonstrated in the attached vi.

Enjoy !

Unfortunately, if memory serves, that method is
a) a private method (at least before 8).
and b) not working in 7.0.

Hello CC,

very nice example!

One problem arised when I tried to use this:
How can I set a certain cursor, when there are more than one?
Somehow LabView doesn't tell me the correct activated cursor... Even when I activate a cursor by mouse clicking in the cursor palette, LabView always sets a different cursor...
