The multiline chart plots up to 3 lines on a chart for analysis. Ords should be bound to histories with similar time frames for advanced comparison. It updates in real-time and uses bql queries to collate the data. The chart has a number of configurable properties that can be used to modify look, feel, and functionality. Also check out the Energy View Template.

Changing Widget Properties - most properties are self-explanatory but some require some explaining.
Label to show for each line. If the degrees symbol needs to be used, use:
Set upto 3 ord values. Each collection should have the same time frame. E.g. history taken every 15 minutes. 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.
You can reference a history ord directly e.g.
Example 1: |bql:select timestamp,value as 'Kw' order by timestamp DESC
Example 2: ?period=weekToDate|bql:select timestamp, value order by timestamp DESC
Set this to 0 if you don't want points shown on the chart.
How often the chart data should refresh. In milliseconds.
Show Ord on Right Axis:
Set values to true or false so the values show on the right axis of the chart.
Bezier curve tension of the line. Set to 0 to draw straightlines. This option is ignored if monotone cubic interpolation is used. Possible values from 0-1.
Cubic Interpolation Mode:
Algorithm used to interpolate a smooth curve from the discrete data points. Possible values are 'default' or 'monotone'.
You can 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.
