In this section, we will discuss how to create meters and gauges using ChartDirector through a number of examples.

In ChartDirector, meters are classified into 2 main types - angular meters and linear meters. They are represented by the AngularMeter and LinearMeter classes. An angular meter displays a value through rotation of a pointer. A linear meter displays a value through linear movement of a pointer. There is also a variation of the linear meter in which a bar is used instead of a pointer.
