Tridium charting library


The chart has a number of configurable properties that can be used to modify look, feel, and functionality. Change the properties as required. Widget Properties

Changing Widget Properties - most properties are self-explanatory but some require some explaining.

Ord Value - this is the live value of the meter or the main meter value. The ord reference should be a numeric point or numeric writable. It can 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.
You can reference a history ord directly e.g.

Date Format.


  • dddd h:mmtt d MMM yyyy = Friday 9:49am 19 Jan 2018
  • M/d/y = 1/19/2018
  • HH:mm:ss = 09:49:29
  • hh:mm:ss TT = 09:49:39 AM
  • yy/M/d = 18/1/19
  • ddd MMM d \a\t h:mm TT = Fri Jan 19 at 9:49 AM

History BQL.

You must bind the chart to a history bql query.
1. Set the value binding to a actual point.
Example: station:|slot:/Drivers/NiagaraNetwork/AHU1

2. Set the history BQL property.
Example 1: |bql:select timestamp,value as 'Kw' order by timestamp DESC
Example 2: ?period=weekToDate|bql:select timestamp, value order by timestamp DESC

Using in your HTML Page

You can now use the widget in your custom html page as long as the html file is in a appropriate station directory. E.g.:

1. Create an html page and place in your station files directory.
2. Create a div element and give it an id so you can inject the widget into this area. E.g.: widget1.
3. Add the following scripts before the closing head tag or the closing body tag. E.g.:

        <script type="text/javascript">

            var require = {
                paths: {
