In this event, it is handy, for example, to use script to set the properties of other Pmg objects (e.g. trend headers - of the PmgWTable object) that are supposed to change based on the current status of the trend viewer.
| pMe | (Object) Reference to the PmgTrendViewer object where the event rises. |
|---|---|
| pEvent | (Object) Reference to object describing detailed information about the specific event. |
