Using mouse to return waveformgraph coordenates

Highlighted

Hello !!!

 

I am using labview 8.0 and I would like to show the coordenates of a waveform graph in a label when the user moves the cursor into it, otherwise show nothing, is there anyway to do that ???  I would be very grateful if someone could help by sending a vi if it's possible or a pic of how to do it!!!

 

Thanks a lot !!!!!!

Which coordinates are you referring to? Do you mean the pixel coordinates, or the XY values of a point that's plotted that happens to be below the cursor?

 

Either way, you want to respond to the MouseMove event as shown in the attached example. Perhaps you want a cursor instead?

Hi!!

 

Thanks for the help, but... it would be possible without the cursor ??? just the mouse movemente ???? because in my graph I have to plot 3 different vectors ...

 

Thanks!!

ps: it's also possible to renitializa (show ceros or blank) if you are not in the graph ????

The example I put together displays the results for both the mouse move as well as using a cursor. If you move the mouse around on the graph the indicators on the right will update. It wasn't clear exactly what you wanted.

Again, it's not clear what you are referring to: i.e., whether you're talking about the pixel coordinates, or the XY values, or to a specific point on the plot. For instance, if the cursor is on the plot line, but not on a specific plot point, what should the indicators display?
