Because the trend chart is an object in CimEdit, you can specify events that trigger actions.
Trending offers you a list of methods to use for an Invoke method action that can be triggered by an event.
A method is a function that operates on a Trend control in CimView.
You can customize one or all of these methods so they will change or enable/disable an aspect of the trend chart when their associated event occurs.
