All Implemented Interfaces:

Serializable

public class TachometerGaugeView
extends ItemView

Shows a tachometer visualization of a Gauge.

The tachometer has 3 different sections: too low, normal, too high which can be customized by setting colors and the areas. It's also possible to specify a start value and to simulate floating point support by specifying a divide factor.
Supported attributes:

• gauge-tachometer-startvalue: the lowest possible value, default is 0
• gauge-tachometer-section1-start: the value at which the first section starts, default is the startvalue (0).
• gauge-tachometer-section2-start: the value at which the second section starts, default is the value range divided by 3.
• gauge-tachometer-section3-start: the value at which the third section starts, default is the value range multiplied by 2/3.
• gauge-tachometer-section1-color: the color of the first section
• gauge-tachometer-section2-color: the color of the second section
• gauge-tachometer-section3-color: the color of the third section
• gauge-tachometer-clockface-color: the outer color of the tachometer, defaults to black
• gauge-tachometer-needle-color: the color of the tachometer needle/pointer/indicator, defaults to red.
• gauge-tachometer-factor: an integer factor by which all given values are divided for simulating floating point. A factor of 10 and a value of 14 will result in a shown value of 1.4, for example.
