public class NeedleGauge

extends java.awt.Panel

implements java.io.Externalizable

This class implements Needle demo guage which enables continuous monitoring of the signals visually. The component is implemented as a bean and provides properties that help it to interface with other data retrieving tools.

This bean provides powerful designing aspects by providing following user friendly properties
Name the name of the gauge
Caption the caption of the gauge
Maximum the maximum value of the needle
Minimum the minimum value of the needle
CaptionFont represents the font which is used to display the caption
NumberFont represents the font which is used to display the number
PanelColor represents the color of the background panel under which this bean resides
Unit represents specified unit system to display the value
NewZoneValues represents the each zone , Each zone has the name, zone color , low value ,high value, grad value, subgrad value
NeedleValue represents the value of the gauge
ScaleGrad represents the scale system of this bean
