It seems like you need to use the event structure. Have an event structure that handles the corresponding mouae event in the waveform graph. Put the code that calculates the difference between the cursors for this event and the VI should work as you need.

Hello Prakash K
Thanks for your help, If you see the attachment I use Waveform Graph events for mouse down & mouse leave as you said but it doesn't work correctly I think , there was a bug in Waveform Graph events.

Hi Behzad,

Try doing something like in this VI.

That was great,and I think at last there was no way to get out of polling.
Thank you very much Prakash K .
