All attributes of a graphical view and its associated points are editable in the graphical view edit page. Because points can belong to multiple views, in this context points are referred to as point views.
All graphical views have a name by which they are referred within lists of graphical views. This name should, but is not required to, be unique. A view may optionally have a Background image upon which point views are superimposed. Users can use any type of image displayable within a browser for the background image, including GIF, JPEG, and PNG. The Anonymous access attribute determines whether users who have not logged in may access the view. Edit means that anonymous users can set the values of settable points in the view. Read means that anonymous users can access the view, but not set point values. None means that anonymous users may not access the view.
To add a point view to the view, choose the point from the Point drop down list, and then click the add point view icon (). If you have a large number of points defined, the point filters can help find the point you need. Show duplicates determines whether points that are already in the view are available to be added again. Show disabled determines whether disabled points (including points that belong to disabled data sources) are displayed in the list. The data source drop down control causes only the points from the selected data source to be displayed in the list.
Once a point has been added to the view, its default representation is the generic point icon ()—once the point's value is determined the default rendering of that value will be displayed instead. The view editing page behaves similar to the view page in that the current value of the point is displayed and updated so that users can see exactly how the point will appear on the view.
By default the point view will be added at the center of the view. Point views can be positioned by dragging and dropping them anywhere within the bounds of the background. Note that point views can overlap one another.
The rendering of a point view can be changed by hovering over the point view to display the editing controls. The controls shown in the view editing page differ from those in the view page except for the information control (), which displays the current value and last change time for the point.
Attributes of the point view can be set by clicking on the point view edit icon (). When clicked, an editing panel will be displayed that allows attributes of the point to be overridden within the context of the graphical view. For example, if a point is normally settable, it can be altered so that it is not settable within the view (although non-settable points cannot be made settable).
The graphical rendering of a point can be changed by clicking on the point view graphical rendering icon (). When clicked, a panel will be displayed allowing the selection of rendering method for the point. The selection of rendering methods is dependent upon the point's data type. A Basic Renderer displays only the textual representation of the point. A Binary Image graphical renderer applies only to binary points, and allows the one of two images to be displayed depending upon the current value of the point. Animated images are supported, so animations can be used to visually indicate when a piece of equipment as running vs. when it is not. The textual representation of a point can also be displayed over the images by selecting the Display Text option. The Multistate Image renderer can be used to visually quantize a numeric point. Using the Min and Max values, the images are uniformly distributed over the numeric range and displayed appropriately.
Point views can be deleted by clicking the delete point view icon ().
All changes to graphical views are saved only when the Save button is clicked. If incorrect changes have been made to a view, they may be aborted by clicking the Cancel button. To delete the entire view, click the Delete button.
