A glossy semi circular gauge, used to display numerical data.



This gauge widget is based on dojox.gauges.AnalogGauge. It provides a way to display data on a semi circular gauge with a glossy appearance. It is created with predefined indicators and thus is ready to use.


Creating a default semi circular glossy gauge requires a few parameters: size and eventually a background color. The others gauge’s parameters such as start and end angle, minimum and maximum values, etc... have default values. Thus, you can quickly use the gauge in you application and customize it according to you needs. Here are the other customizable parameters.

width “300” The width of gauge.
height “300” The height of the gauge
min “0” The minimum allowed value.
max “100” The maximum allowed value.
value “0” The current value.
majorTicksInterval “10” The interval between each majors tick
majorTicksColor “#c4c4c4” Color of the major tick marks on the scale
minorTicksInterval “5” The interval between each minor tick

font “normal normal normal 10pt sans-serif” Definition of the font used to display the values on the scale
textIndicatorFont “normal normal normal 20pt sans-serif” Definition of the font used to display the current value
textIndicatorVisible “true” Indicates if the text displaying the current value is visible
textIndicatorColor “#c4c4c4” The color of the text displaying the current value
majorTicksLabelPlacement “inside” Indicates how label are placed relatively to the tick marks: either “inside” or “outside”. “inside” means between the ticks and the center of the gauge, and “outside” means between the gauge’s border and the tick marks
noChange “true” Indicates if user can change the value of the gauge by interacting with the needle
