argand diagram

[LeoLiu]

Now I got a voltage value and the phase value, I want show it in a agrand diagram , what should I do?

[Dennis_Knutson]

Display on an XY graph.

Thank you , Dennis

But the value I got is a number, just display it on the XY graph directly?

For example, if the voltage is 30V, and the phase angle is 30 degree, could you please show me a simple circuit?

Regards

Yes, just display it directly. You would need to change the point style of the XY graph. The default is none so a single point would not be seen. I don't know what kind of circuit you are asking for. A basic block diagram is below. Also look at the shipping examples. This is a pretty trivial task in LabVIEW. Have you taken the basic tutorial?
