OpenNTF: XPages AnalogGauge Custom Control
I have just submitted my contribution for the OpenNTF Development Contest. I have created an AnalogGauge Custom control.
You can place multiple Gauge controls on a XPage. Each control can have one or more indicators ( Line, Arrow, Needle) and the Gauge segment can be split into multiple ranges.
See the documentation for more information on how to implement the control in your application. The control uses dojo and the source is pure Javascript. You can easily modify the code if you want to do so.
