Adding virtual points to a chart

When adding the Niagara virtual point (via dragging from the Virtual space or some other means) to a web chart on a Supervisor, if the remote point on the controller has a history, the chart attempts to resolve the history on the Supervisor and use it to initialize the web chart. Note that in order to detect the matching histories for the points from the subordinate station, the histories must be already imported or exported to the Supervisor

Prerequisites:

Connection to a Supervisor station and a subordinate station
Discovered and added points (configured with history extensions) from the subordinate station

Perform the following steps:

Open the Property Sheet view of the NiagaraNetwork virtual component under the Supervisor’s Virtual space, and set the Persist Virtual Fetched Tags property to true.

NOTE: On the NiagaraNetwork, the Persist Virtual Fetched Tags property works in conjunction with the Tags to Fetch property.
Right-click the Supervisor’s History space and click Niagara History Import Manager.
In the History Import Manager view, select the discovered Histories on the subordinate station’s points that you want to import and click Add.
In the Supervisor’s NiagaraNetwork under the subordinate station, double-click on the Points folder to open the Point Manager view.
Select the discovered points that you want to subscribe to and click Add.
Under the Supervisor Config node, open a Chart view on a folder or other component, and drag one or more points from the Virtual space onto the web chart.

With the Supervisor station subscribed to the points on the subordinate station, when you drag one or more individual virtual points from the Virtual space onto a web chart on the Supervisor, it is able to resolve the histories and initialize the web chart.
