Hi

Possible a very simple question but how do you link a SFC to the component on the vision window. I tried typing in the name to Instance ID but it does not allow me to enter it.

You need to start an instance of a chart before you can display anything.

You have the chart “Test” defined, but no instances of it are running. Every time you start a chart, you get an instance id for that chart (system.sfc.startChart)
