Live History Chart view
This view displays historical data (trend data) as the default view for the HistoryPointList component and a secondary view on history extensions. It combines the historical plot of the History Chart with a continuing
live plot that updates according to a sample rate that can be configured. It begins with a start time to the current time
and continuously updates as the source generates new data.

- The Resize Control resizes the pane. Drag the left border to widen or narrow the pane in the view.

As the chart plots new data the view continuously updates. When data fill the chart area, the screen scrolls horizontally to keep showing the latest data.
