Adding data to a chart

Using the drag and drop technique you can add data to a Chart view while the chart is rendering. You can add one or more control points, histories, schedules, as well as bookmarked ords (in a browser station connection) to a Chart view.

Prerequisites:

Connection to a station.

The following types of data can be added to a web chart:

control points (Boolean, Enum or Numeric points, with or without history extensions)
history records
schedules
containers with multiple child components such as a points folder
NOTE: When adding a points folder to a web chart, only the first 10 histories are plotted.
data from Series Transform
NOTE: Series Transform data must have a timestamp property and a non-String value in order to resolve into a chart. Also, “live mode” and Delta values are not available.
bookmarked ords (station connection in a browser)
real-time and historical data managed by the Niagara Analytics Framework

Perform the following steps:

Expand the Station node in the Nav tree.
Open a Chart view (open either a new chart view or an existing .chart file).

Add data using any of the following methods:

Method	Description
Drag and drop a single component	In the Nav tree, click to select a component and then drag and drop onto the Chart view.
Drag and drop multiple components	Using Ctrl + Click, select multiple components, drag and drop onto the Chart view.
Click Add Series to select multiple components or a container	Click (Add Series), in the Add Series dialog expand the Nav tree and use Ctrl + Click to make multiple selections and click OK.
In a web browser station connection, drag and drop a bookmarked ORD	First, bookmark the source component’s ORD, open a Chart view and then drag and drop the bookmarked ORD onto your chart.

Regarding how web charts display units of measure, when adding an additional component that has the same unit of measure, the Y-axis scale changes to accommodate the added data.

When adding an additional component with a different unit of measure, the units display along the opposite Y-axis.

And in a chart containing three or more different types of data the chart displays two different units on the Y-axis at a time but you can switch the units displayed on the Y-axis by clicking on the visibly dimmed axis label.

NOTE: In Niagara 4.2 and later, when adding a proxy point from a Supervisor to the web chart, if the point does not have a local enabled history extension and the remote point on the controller does, the chart attempts to resolve the history on the Supervisor and use it to initialize the web chart. In order to detect the matching history, the history must have already been imported or exported to the Supervisor.
