Subgraph / region status

» A subgraph is specified within a graph by

   graph: { title: "subgraph title"  subgraph entries }

» A region is specified by

   region: { status: folded or boxed
             source: "start node title"
             target: "end node title"
             class : edge class to be folded or boxed
             range : neighbor region range
           }

» The class of an edge is specified by

   class: integer

   graph: {
           graph: {title:"a" shape:triangle label:"subgraph"}
          }
   // when the subgraph "a" is folded,
   // it will be represented by a triangle

» Global summary node/edge attribute values are specified by

   foldnode.attribute: value
   foldedge.attribute: value
   // these can only be specified for the top-level graph

Subgraph example (see slide)

graph: {foldedge.color: darkred

        node: {title:"1"}  node: {title:"2"}
        node: {title:"3"}  node: {title:"4"}

        graph: {title: "5"  shape: circle  textcolor: red
                node.textcolor: 8  edge.color: 8
                node: {title:"6"}
                node: {title:"7"}
                node: {title:"8"}
                edge: {source:"6" target:"7"}
                edge: {source:"6" target:"8"}
               }

        edge: {source:"1" target:"2"}
        edge: {source:"1" target:"5"}
        edge: {source:"2" target:"3"}
        edge: {source:"2" target:"4"}
       }

Region example (see slide)

graph: {foldedge.color: darkred
        foldnode.textcolor: red

        node: {title:"1"}  node: {title:"2"}
        node: {title:"3"}  node: {title:"4"}
        node: {title:"5"}  node: {title:"6"}
        node: {title:"7"}  node: {title:"8"}

        edge: {source:"1" target:"2"}
        edge: {source:"1" target:"3"}
        edge: {source:"2" target:"4"}
        edge: {source:"2" target:"5"}
        edge: {source:"3" target:"6" class: 1}
        edge: {source:"3" target:"7" class: 1}
        edge: {source:"6" target:"8" class: 2}

        region: {status: folded  source:"3"  class: 1}
       }

   status: folded or boxed or unfolded or
           clustered or wrapped or exclusive

» A region may have multiple sources and/or targets

   source: "one" "two" "..." "n"
   target: "One" "Two" "etc" "m"

» A region may unite edges of different classes

   class: 1 28 42 14

» Default attribute values

   foldedge.thickness: 3
   foldedge.label: "..."
   status: unfolded
   The default neighbor region range is 3
   It can be changed interactively in the View Dialog Box

   region:  { status: folded  source: "3" }  // this is OK
   region : { status: folded  source: "3" }  // this won't work

» aiSee understands the following alternative notations:

   state:       // instead of status:
   white        // instead of unfolded
   sourcename:  // instead of source:
   targetname:  // instead of target:
