Alarm Pie Chart

The alarm pie chart widget is used to display a pie chart of alarm statuses for a particular thing and alarm.


Field	Description
Name	The name of the widget, shown at the top of the widget.
Thing key	The thing key this widget should respond to. If left blank, the widget inherits the thing key from the dashboard.
Alarm key (mandatory)	The key of the alarm to show.
Aggregation	What aspect of the alarms should be grouped together. Count groups together the number of alarms triggered. Duration groups together the time that the thing was in each alarm state.
Show legend	If a legend should be displayed at the bottom of the pie chart. Clicking the color in the legend changes the slice displayed in the chart.
Show border	If the widget should have a border around it.

When you move the mouse pointer over a slice, the pie chart highlights that slice and displays the name of the alarm and values specific to that alarm.
If you are displaying the legend, moving the mouse pointer over a color in the legend highlights that slice. Clicking the color in the legend turns the slice on and off in the chart.
