Viewing Venn Diagrams
Once a Venn diagram has been created it is displayed in the draw area of the
Structural Reasoner. By moving the mouse over the diagram
a tool tip will be displayed. Two kinds of tool tips are possible. The
type of the tool tip depends on the location of the mouse cursor:
- If the mouse is near the border of a diagram area the tool tip
will show how many connections there are from the nodes in that area
to the nodes in the other.
- If the mouse is not near the border of the area the tool tip will
show how many nodes there are in that area.
By right-clicking on the diagram a popup menu can be opened.
The popup menu contains the following options:
- Show attributes weights
- Shows a table
of attribute weights
- Properties graph
- Creates an attribute
graph based on the Venn diagram and displays it.
- Distribution graph
- Creates an attribute
distribution graph based on the Venn diagram and opens it in a
dedicated window.
- Show non-empty regions
- Selecting this option will change the diagram so that only those regions
which contain network nodes will be filled with color. The empty regions will
be drawn white.
- Use Attribute aliases
- Selecting this menu option will affect the tool tips. When this item is
checked the manu options will contain the names of the attributes instead
of their identifiers (e.g. "P5" will be replaced by its full name).
- Redraw diagram
- Selecting this menu option redraws the diagram normally so that no area
is highlighted (unselects Show non-empty regions).
