Figure 21-8. Topology View–Spring Layout
The Spring Settings for spring layout include the following:
-
Propagate –When selected, changes to any individual entity cause the positions of connected
entities to be recalculated.
-
Specify layout size –In pixels. You must check this before specifying the number.
-
Horizontal / vertical alignment –Enter the number of pixels between objects (applied if
Automatic horizontal spacing is unchecked).
-
Use object’s sizes –Uses the size of each object to determine its weighting and relative placement,
rather than a point.
-
Fix selected objects –Specifies that the selected objects remain in their current position.
-
Automatic edge length –This calculates the length of the links and the relative spacing of the
entities with respect to the containing window. Click to select, or provide the
Edge length
constant
(the length of links and the relative spacing of entities) , Repaint period (seconds
between screen refreshes)
, and Epsilon (when the iterative process for the spring embedder
should stop. The greater this constant, the faster the layout, but the more distant the final
position from the optimal layout.)
.
- Single components settings –Automate these by checking Automatic horizontal spacing , or
manually enter Horizontal or Vertical Spacing (in pixels).
