I'm a new Labview user and  I try to plot two parameters in a XY graph. and my XY graph not showing any graph.

Please can you tell me why. This is my VI

 

Thanks

To produce an xy graph with a time element - see the attached picture

 

You may also require a timer within the loop to prevent the vi taking excessive computing power.

Hi FrancoM,

 

In fact you can see one point in X and Y, because you chose the VI read Analogique 1D wfm Nvoies 1Echant. So this VI will return a waveform with a array of 1 élement for X and Y. 

If you want to plot more point you need to use the VI read Analogique 1D wfm Nvoies NEchant.
