public class LevelGauge

extends java.awt.Panel

implements java.io.Externalizable

This bean component allows the user to pipe the data through retrieval tools and check the level of the of data between the minimum and maximum.

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 level
Minimum the minimum value of the level
CaptionFont represents the font which is used to display the caption
NumberFont represents the font which is used to display the number
BorderColor the border color
ZoneColor represents the color of the zone cell below the warning area
WarningZoneColor represents the warning area cell color
AlarmZoneColor represents the alarm area cell color which resides above the warning level
Value the current value
Warning represents bottom level of the warning area
Alarm represents the bottom level of the alarm area
