Overview

A Graphical view is similar to a watch list, but instead provides a graphical representation of selected points. Point values and value times update automatically—you do not need to refresh the page. (In fact, the system operates more efficiently if you don't.)

Selecting a graphical view

A user may have multiple graphical views, but may only view one at a time. Use the dropdown control to select the view that you wish to display. To create a new view, click the add icon () in the top right-hand corner of the watch list section. To edit an existing view, click the edit icon (). In either case, the Graphical view edit page will be displayed.

You may see graphical views in your list that you did not create. If so, these views were "shared" with you by the person who created them. You will be at least allowed to view them, but you may not be allowed to set values via the view if you were not granted "set" permission. If you no longer wish to have the view in your list, use the delete icon () to "unshare" the view. (Unsharing does not delete the view.)

Background images

Graphical views may optionally be presented upon background images. Backgrounds can be set in the graphical view editing page.

Points in graphical views

A point can belong to multiple graphical views, so you can create views that are as specific as you require.

The representation of each point in your view depends upon that point's configuration. Points can be rendered as simply a current value, or an arbitrary icon set can be used that visually represents the point's value. When the user rolls over the point with the mouse, a set of controls will be displayed (unless they have been explicitly suppressed). The actual controls displayed will also depend upon the point's configuration. Hovering over the info icon () will display the point's current value and last change time. Points that are settable (and for which you have permission to set) will show a set icon (). Hovering your mouse over this icon will present options for setting the point. Points that are configured for charting will show a chart icon (). Hovering over this icon will present the current chart. Charts are updated automatically, like values and times, so when new data is available the chart will update itself. If a warning icon () is displayed beside a point, it indicates that is inactive, either because it or its data source are disabled. A wait indicator () means that the point currently has no value, and is likely waiting for its value to be received.
