Thanks for answering

What I really wanted to know is that is it possible to get
the values under the mouse cursor into a table. So
there is a cursor display to mouse coordinates (x,y) but
I would like to get these values into a table 'naturally' by doubleclicking
the mouse over a certain point in
a graph.
Well I wonder if this is just a daydream ....:)

Hi,

If you belong LabVIEW 6.1, there is an example you can maybe adapt for your case.

This example is located here: Help->Find Examples...->New Examples for LabVIEW 6.1->Events->Draw Graph with Events.vi

I hope it will help you.

Jack,

If you do not have labview 6.1 you can still get the mouse coordinates by using a call to the windows 32 API dll. There's a library called LVutil32.zip which contains a set of llb's and a dll(see instructions to install). One of them is the winsys.llb and there's a get cursor positon.vi:

You can compare those coordinates to the cursor coordinates on the graph to correlate them.

There's also a VI that allows you to capture a mouse double click.

Hope it will help.
