What is a Phasor graphic?

A Phasor graphic is a WebCTRL graphic (phasor.view) that shows dynamic voltage and current readings for an electric meter.

As shown in the example below, you can custom add other items to the Phasor graphic such as a trend graph and other data. You can also add multiple phasor graphics to the phasor.view file.
