DOT file format

Start på graf:

digraph g {

Node:

"(10,70)" [label = "(10,70)"]
"(20,50)" [label = "(20,50)"]

Edge:

"(10,70)" -> "(20,50)"[label = "Vestervoldgade, 22.0"]

Slut på graf:

}

Positionering af noder

Hvis du vil binde en node til en bestemt position på grafen, kan du bruger pos. Husk at du skal sætte Layout: til "Energy Minimized" og Position: til "Edges Only".

"(10,70)" [label = "(10,70)", pos="10,70"]
"(20,50)" [label = "(20,50)", pos="20,50"]

Positionering ved hjælp af commandline

Følgende kommando genererer en png-fil, hvor der tages hensyn til nodernes position.

neato -Tpng -oOutput.png -n2 -Gsplines  Input.dot 

Under Mac OS X findes neato under /Applications/Graphviz.app/Contents/MacOS/
