From Scripting Using the system.sfc.startChart method of the scripting API, a chart can be started from anywhere. The chart must be in Callableexecution mode.
From an Enclosing Step A chart can spawn an instance of another chart using anEnclosing Step.
Automatically A chart whose execution mode is RunAlways is automatically started when the Gateway starts up. If the chart stops, the Gateway does not re-execute it. If you want a chart that runs all the time, it should be designed to never stop, for example, by looping back upon itself continuously.
From the Designer While designing a chart, you can start instances of it from the Chart Control panel in the Designer using the Startlink.
