The Options section of the Style Rules pane
allows you to enable or disable various facilities at the level of
the diagram as a whole. Each diagram you work on has its own style
sheet and therefore its own options.
There are options for the following aspects
of the diagram:
- BackgroundThe Background option allows you to display a color, a pattern, or a graphic in the background of your diagram.
- Background MapThe Background Map option allows you to add a background map and to position objects in a georeferenced way (with latitude and longitude). For an example, see Using background maps. For full details of map styling, see The Map renderer in Developing with the JViews Diagrammer SDK.
- BlinkingThe Blinking option allows you to add blinking to the symbols that make use of this feature. You can define the blinking period. For full details of blinking styling, see The Blinking renderer in Developing with the JViews Diagrammer SDK.
- Graph LayoutThe Graph Layout option handles the relative positioning of the data objects in the diagram. See also Graph and link layouts. For an example, see Using the Graph Layout Wizard.
- Info BalloonsInfo Balloons are text elements attached to a node or link but displayed only when the object is clicked. For full details of Info Balloon styling, see The InfoBalloon renderer in Developing with the JViews Diagrammer SDK.
- LegendThe Legend option activates an optional legend displayed by default at the lower left of the diagram. The legend provides an explanatory function and a filtering function. For an example, see Adding and customizing a legend. For full details of legend styling, see The Legend renderer in Developing with the JViews Diagrammer SDK.
- Label LayoutThe Label Layout option allows you to place the labels of the nodes and links so that they do not overlap with the nodes and links.
- Link LayoutThe Link Layout option handles the positioning of links to avoid them overlapping with one another or with nodes.
- SubgraphsThe Subgraphs option allows you to expand a node by clicking the handle in the corner to display subnodes within it. This option is compatible with XML data only. For full details of subgraph styling, see The SubGraph renderer in Developing with the JViews Diagrammer SDK.
- Zoom ThresholdsZoom thresholds prevent the node size from becoming too small or too large when you zoom. They are generally most useful when you have a background map because the map size and the node sizes may be very different.
There is a Styling Customizer for each of
these facilities to set the styling properties. The Styling
Customizer appears in the lower pane of the Designer when you
select the option in the Style rules pane.
