Drag and drop the Spectrum Gauge widget from the palette onto your px view. It automatically updates when the point or history value changes. Its completely configurable and easy to use.
1. Copy the spectrumGauge-ux.jar file to your modules directory.
2. Open the module from your palette file.
3. Drag and drop the widget from the palette onto your px view.
The gauge has a number of configurable properties that can be used to modify look, feel, and functionality. Change the properties as required.
Main Chart Binding:
Set this to an absolute ord, e.g.
station:|slot:/Drivers/NiagaraNetwork/AHU5 or relativized ORD e.g.
The ord should point to a numeric point/writable that has a numeric interval extension.
The background (the area within the circular part of the widget) can be changed to a solid color, gradient, image, or null(transparent). The image must reference a file ord reference e.g. file:^myImage.jpg, and fit within the bounds of the widget.
Make sure the layout width/height are equal otherwise the gauge will not scale correctly.
There are 3 properties related to the segements.:
Segments: which are the percentage size for each segment
SegmentFilledColors: are the areas which are shaded when the value reaches the segment value
SegmentUnFilledcolors: opposite to segmentFilledColors.
You can bind the gauge to a history reference. Change the properties as required:
1. Set the value binding as normal.
The value binding must be set in order to gather history records for the point.
2. Set the history BQL property.
