Drag and drop the Donut 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.
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.
Canvas Background Property:
The canvas background (the area behind the widget) does not go transparent in Workbench mode, but can be changed to a color of your choice.
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.
|bql:history:HistoryRollup.rollup(history:RollupInterval 'monthly')|bql:select max
|bql:history:HistoryRollup.rollup(history:RollupInterval 'monthly')|bql:select min
|bql:history:HistoryRollup.rollup(history:RollupInterval 'monthly')|bql:select avg
|bql:history:HistoryRollup.rollup(history:RollupInterval 'monthly')|bql:select sum
You can now use the widget in your custom html page as long as the html file is in a appropriate station directory.
Widgets and drivers must be licensed with us. Licenses are bound to the stations host Id. You will be provided access to the Software and Licensing Portal where you can manage your own licenses. Here you can add, update, or delete licenses as needed.
There are few ways to get a license file:
1. Add our licensing module to your station services. This module automatically retrieves the license from our servers and saves it to your stations shared folder directory.
2. Alternatively, Login to the Software and Licensing Portal (link provided in Order Confirmation) and add your host id's as needed. Copy the license file to the stations shared directory.
Finally, make sure the station user has access to WLicenseService in the user management and category service section.
