The Live History Chart view is available directly from the history extension component and also from a view on the HistoryPointList component. The history extension view displays the single point in a live chart plot, while the HistoryPointList component, when configured, displays all List Points that it contains.
The following procedures describe how to setup these views.
Live History Chart view from a History Extension
Use this direct "history extension method" to display a single live charting point. If you need to view several points plotted
simultaneously, then use the HistoryPointList component and the steps in the section, Live_Chart_view_from_a_HistoryPointsList_Component.

-
Right-click the desired history extension component in the workbench nav tree. The popup menu displays.
