largest context that makes sense. |
| object | pos: Position of node, or spline control points, in points. |
| str | samehead: Edges with the same head and the same samehead value are aimed at the
same point on the head. |
| str | sametail: Edges with the same tail and the same sametail value are aimed at the
same point on the tail. |
| int | showboxes: Print guide boxes in PostScript at the beginning of routesplines if 1,
or at the end if 2. |
| str | style: Set style for node or edge. |
tail: The edge's tail (destination) node | |
| boolean | tailclip: If true, the tail of an edge is clipped to the boundary of the tail
node; otherwise, the end of the edge goes to the center of the node, or
the center of a port, if applicable. |
| str | tailhref: Synonym for tailURL. |
| str | taillabel: Text label to be placed near tail of edge. |
| string | tailport: Indicates where on the tail node to attach the tail of the edge. |
| str | tailtarget: If the edge has a tailURL, this attribute determines which window of
the browser is used for the URL. |
| str | tailtooltip: Tooltip annotation attached to the tail of an edge. |
| str | tailURL: When the output format is imap or cmap, if tailURL is defined, it is
output as part of the tail label of the edge. |
| str | target: If the object has a URL, this attribute determines which window of the
browser is used for the URL. |
| str | tooltip: Tooltip annotation attached to the node or edge. |
URL: Hyperlinks incorporated into device-dependent output. | |
| float | weight: Weight of edge. |
| Method Details |
|---|
__iter__(self)Iterates over (tail, head) |
| Property Details |
|---|
arrowsizeMultiplicative scale factor for arrowheads. |
commentComments are inserted into output. Device-dependent |
decorateIf true, attach edge label to edge by a 2-segment polyline, underlining the label, then going to the closest point of spline. |
fontcolorColor used for text. |
fontsizeFont size, in points, used for text. |
headThe edge's head (source) node |
headclipIf true, the head of an edge is clipped to the boundary of the head node; otherwise, the end of the edge goes to the center of the node, or the center of a port, if applicable. |
headhrefSynonym for headURL. |
headlabelText label to be placed near head of edge. See limitation. |
headtooltipTooltip annotation attached to the head of an edge. This is used only if the edge has a headURL attribute. |
headURLFor the output format imap or cmap, if headURL is defined, it is output as part of the head label of the edge. See limitation. |
hrefSynonym for URL. |
labelText label attached to objects. If a node's shape is record, then the label can have a special format which describes the record layout. |
labeldistanceMultiplicative scaling factor adjusting the distance that the headlabel(taillabel) is from the head(tail) node. The default distance is 10 points. See labelangle for more details. |
labelfloatIf true, allows edge labels to be less constrained in position. In particular, it may appear on top of other edges. |
labelfontcolorColor used for headlabel and taillabel. If not set, defaults to edge's fontcolor. |
labelfontnameFont used for headlabel and taillabel. If not set, defaults to edge's fontname. |
labelfontsizeFont size, in points, used for headlabel and taillabel. If not set, defaults to edge's fontsize. |
layerSpecifies layers in which the node or edge is present. |
lenPreferred edge length, in inches. |
lheadLogical head of an edge. When compound is true, if lhead is defined and is the name of a cluster containing the real head, the edge is clipped to the boundary of the cluster. See limitation. |
lpLabel position, in points. |
ltailLogical tail of an edge. When compound is true, if ltail is defined and is the name of a cluster containing the real tail, the edge is clipped to the boundary of the cluster. See limitation. |
minlenMinimum edge length (rank difference between head and tail). |
posPosition of node, or spline control points, in points. In neato and fdp, pos can be used to set initial position of a node. Concerning this, see the -s command line flag. |
sameheadEdges with the same head and the same samehead value are aimed at the same point on the head. See limitation. |
sametailEdges with the same tail and the same sametail value are aimed at the same point on the tail. See limitation. |
showboxesPrint guide boxes in PostScript at the beginning of routesplines if 1, or at the end if 2. (Debugging) |
styleSet style for node or edge. For cluster subgraph, if "filled", the cluster box's background is filled. |
tailThe edge's tail (destination) node |
tailclipIf true, the tail of an edge is clipped to the boundary of the tail node; otherwise, the end of the edge goes to the center of the node, or the center of a port, if applicable. |
tailhrefSynonym for tailURL. |
taillabelText label to be placed near tail of edge. See limitation. |
tailportIndicates where on the tail node to attach the tail of the edge. See limitation. Possible values: 'n', 'ne', 'e', 'se', 's', 'sw', 'w', 'nw', 'center' |
tailtooltipTooltip annotation attached to the tail of an edge. This is used only if the edge has a tailURL attribute. |
tailURLWhen the output format is imap or cmap, if tailURL is defined, it is output as part of the tail label of the edge. See limitation. |
targetIf the object has a URL, this attribute determines which window of the browser is used for the URL. See W3C documentation. |
