Meter charts (the following figure) measure the most recent variable value from the variable associated with that meter. Meters can be configured to show increasing levels of severity. For example, you can create a meter that measures the total number of unassigned High priority tickets. You can configure the meter to display the total number of tickets in colored zones (up to 20 ticket counts in the green zone, between 20 and 40 tickets in the yellow zone or Warning Threshold, and 40 to 50 tickets in the red zone or Alert Threshold).
You can also set up a Flashboards Alarm to send a warning to a specified recipient when the needle enters the Alert Threshold.
