Bug 14470
Материал из CustisWiki
From http://www.graphviz.org/doc/info/attrs.html#k:escString
In addition, if the associated attribute is label, headlabel or taillabel, the escape sequences "\n", "\l" and "\r" divide the label into lines, centered, left-justified, and right-justified, respectively.
But actually, this alignment works only for first two lines. Example:
digraph G{ leftjustified[shape=plaintext label="leftjustified\lline2\lline3"]; rightjustified[shape=plaintext label="rightjustified\rline2\rline3"]; }
This bug tested on Windows and Linux Graphviz versions 2.0, 2.2, 2.6.
