Wgraph:Command Reference,group=edge

align

left,center,right

center

defines the horizontal alignment of a label within the object.
This command is an alias for text_mode. left_justify and right_justify can be used instead of left and right.

arrow_size

integer

10

The size of the arrow pointing to the target object of an edge. A value of 0 will suppress the arrow.

arrow_style

see description ..

solid

Defines the shape of the arrow pointing to the target object of an edge. You can concatenate (using ' + ') a string containing the following tokens:

[filled] [half] {circle, box, rhomb} and {solid,none,line,slash,dslash}

Example: arrow_style="filled half circle + rhomb + none + dslash"

class

unsigned integer

1

You can assign an edge to a class. Classes have numeric id´s and can be assigned a name using the classname attribute. The local aiSee client allows to hide/show edges based on their class.
Wgraph supports this only for backward compatibilty reasons. Using edgetypes and nodetypes is more flexible. See type. Wgraph maps its edgetypes to some extent to classes so that the local aiSee client will still see some edge classes even if you do not use that concept within Wgraph.

font

string (= filename in aisee/fonts)

(vector font)

By default letters are made of polygons. This works always but costs a lot of time and makes svg files quite large. It is highly recommended to use something like helvR10 as default font for all nodes and edges.

from

string (node id)

-

normally this attribute will be set as a part of an edge definition ("edge A B {}" --> A is the 'from' attribute). But you can also set it explicitly ( "edge {from A to B}" ). "from" in Wgraph corresponds to the "source" of an edge in aiSee/GDL.

boolean

no

If set to yes the graphical object will not be drawn. Hidden objects will still influence the layout.
