public class ThermometerPlot
extends Plot
implements ValueAxisPlot, Zoomable, Cloneable, Serializable

A plot that displays a single value (from a ValueDataset) in a thermometer type display.

This plot supports a number of options:

1. three sub-ranges which could be viewed as 'Normal', 'Warning' and 'Critical' ranges.
2. the thermometer can be run in two modes:
   • fixed range, or
   • range adjusts to current sub-range.
3. settable units to be displayed.
4. settable display location for the value text.
