ShowAlarmIndicators property

Use the ShowAlarmIndicators property to specify whether or not the chart should show the alarm indicators row in the table. This is a design-time and a run-time property. However, changing the value will not update the chart until the next time the chart is refreshed or the DisplayChart() method is called.

If set, an alarm indicator row will be added to the table that includes one or two of the following indicators above each sample point in the chart. When two indicators are used, the first is for the primary chart and the second is for the secondary chart.

• -, if no control rule violation occurred.

• H, if the violation occurred above the center line

• L, if the violation occurred below the center line

• B, if the violation occurred on both sides of the center line

• T, if the violation is a trend and is not dependent on the position of the points relative to the center line

The following figure highlights indicators in the Alarm row of the table:

You cannot set this property to Null.
