A meter is similar to the speedometer or fuel gauge of a car. It uses a radial scale to display the data range, and a dial to indicate the data value. A meter displays the specific data, utilizing an indicator that moves within a circular range to indicate whether the monitored data is within defined limits. You can select colors for the data range to suit the application, such as green for satisfactory, yellow for caution, and red for alarm.

You can convert meter gadgets into linear gauge gadgets as described later in this document. The example in Figure 8‑41 shows shipped orders illustrated using a meter gadget.
