Graphical Panel Controls: Meter

Meter controls display data using a meter face. The actual numeric value of the signal linked to the control is shown at the top, while the needle points to a representation of the current value in a manner similar to that of an automobile gauge (Figure 1). The range of displayed values is controlled through custom settings.

Figure 1: Two example Meter controls showing how data is displayed both numerically and graphically.

Table 1 lists the properties specific to the Meter control. A list of common properties can be found under Common Control Properties.
