TBbalance

Which rank to move floating (loose) nodes to

type: string, default: ''

Valid options:

"min": Move floating (loose) nodes to minimum rank.
"max": Move floating (loose) nodes to maximum rank.
Otherwise, floating nodes are placed anywhere.

Despite the name TBbalance ("Top-Bottom Balance"), this also works with left-right ranks, e.g. rankdir=LR.

Examples:

Default Behaviour

digraph {
    layout="dot"

    { rank="min"; "min" }
    { rank="max"; "max" }
    "min" -> "middle" -> "max"
    
    "Floater 1"
    "Floater 2"
}

Edit in Playground

Floating nodes moved to min rank

digraph {
    layout="dot"
    TBbalance="min"

    { rank="min"; "min" }
    { rank="max"; "max" }
    "min" -> "middle" -> "max"
    
    "Floater 1"
    "Floater 2"
}

Edit in Playground

Floating nodes moved to max rank

digraph {
    layout="dot"
    TBbalance="max"

    { rank="min"; "min" }
    { rank="max"; "max" }
    "min" -> "middle" -> "max"
    
    "Floater 1"
    "Floater 2"
}
