Runtime Interaction with the Chart

You can interact with the chart at run time. When a chart is displaying data, you can do the following:

• Toggle areas of the chart window on and off.

• Zoom on a chart.

• Move the mouse pointer over a sample to see the value of the point.

• Use the scroll bar to move to newer/older data, when the plotted points do not fit on the display. After you stop scrolling, the control waits for a second or two to refresh and redraws the chart.

• Click either of the two alarm indicators in the Alarm row to see the control rule violation description. There is a separate indicator for the top chart (first) and bottom chart (second).

You can also assign a cause to a sample point, add notes to a sample point, mark a sample point as a control move, and mark a sample point to be ignored in sample calculations. These operations are described in the following topics.
