Tacho Gauges
Overview
Bar Tacho and 
Round Tacho gauges are typically used with engine speed or road speed and are available as either a curved bar gauge or a round gauge. They use minimum, maximum and resolution in the same manner as bars but also have labeled segments, the frequency of which is specified by the label frequency property. The label values are divided by the label divisor property and then formatted.
See also Needle Gauge which can be used to draw a pointer over an image background.
