OSAGE(1)OSAGE(1)NAMEosage - filter for drawing clustered graphs
SYNOPSISosage [-(G|N|E)name=value] [-Tlang] [-llibfile] [-ooutfile] [-O] [-P]
[-v] [-V] [files]
DESCRIPTIONosage draws clustered graphs. As input, it takes any graph in the dot
format. It draws the graph recursively. At each level, there will be a
collection of nodes and a collection of cluster subgraphs. The inter‐
nals of each cluster subgraph are laid out, then the cluster subgraphs
and nodes at the current level are positioned relative to each other,
treating each cluster subgraph as a node.
At each level, the nodes and cluster subgraphs are viewed as rectangles
to be packed together. At present, edges are ignored during packing.
Packing is done using the standard packing functions. In particular,
the graph attributes pack and packmode control the layout. Each graph
and cluster can specify its own values for these attributes. Remember
also that a cluster inherits its attribute values from its parent
graph.
After all nodes and clusters, edges are routed based on the value of
the splines attribute.
OUTPUT FORMATS
Osage uses an extensible plugin mechanism for its output renderers, so
to see what output formats your installation of osage supports you can
use ``osage -Txxx'' (where xxx is an unlikely format) and check the
warning message. Also, The plugin mechanism supports multiple imple‐
mentations of the output formats. To see what variants are available,
use, for example: ``osage -Tpng:'' and to force a particular variant,
use, for example: ``osage -Tpng:gd''
Traditionally, osage supports the following: -Tps (PostScript), -Tsvg
-Tsvgz (Structured Vector Graphics), -Tfig (XFIG graphics), -Tmif
(FrameMaker graphics), -Thpgl (HP pen plotters), and -Tpcl (Laserjet
printers), -Tpng -Tgif (bitmap graphics), -Tdia (GTK+ based diagrams),
-Timap (imagemap files for httpd servers for each node or edge that has
a non‐null "href" attribute.), -Tcmapx (client‐side imagemap for use in
html and xhtml). Additional less common or more special‐purpose output
formats can be found at http://www.graphviz.org/cvs/doc/info/out‐
put.html.)
Alternative plugins providing support for a given output format can be
found from the error message resulting from appending a ':' to the for‐
mat. e.g. -Tpng: The first plugin listed is always the default.
GRAPH FILE LANGUAGE
Here is a synopsis of the graph file language, normally using the
extension .gv, for graphs:
[strict] (graph|digraph) name { statement‐list }
Is the top level graph. If the graph is strict then multiple edges are
not allowed between the same pairs of nodes. If it is a directed
graph, indicated by digraph, then the edgeop must be "->". If it is an
undirected graph then the edgeop must be "--". Statements may be:
name=val;
node [name=val];
edge [name=val];
Set default graph, node, or edge attribute name to val. Any subgraph,
node, or edge appearing after this inherits the new default attributes.
n0 [name0=val0,name1=val1,...]; Creates node n0 (if it does not already
exist) and sets its attributes according to the optional list.
n0 edgeop n1 edgeop ... edgeop nn [name0=val0,name1=val1,...];
Creates edges between nodes n0, n1, ..., nn and sets their attributes
according to the optional list. Creates nodes as necessary.
[subgraph name] { statement‐list }
Creates a subgraph. Subgraphs may be used in place of n0, ..., nn in
the above statements to create edges. [subgraph name] is optional; if
missing, the subgraph is assigned an internal name.
Comments may be /*C‐like*/ or //C++‐like.
Attribute names and values are ordinary (C‐style) strings. The follow‐
ing sections describe attributes that control graph layout.
GRAPH ATTRIBUTES
size="x,y" sets bounding box of drawing in inches.
page="x,y" sets the PostScript pagination unit.
ratio=f sets the aspect ratio to f which may be a floating point num‐
ber, or one of the keywords fill, compress, or auto.
pagedir=[TBLR][TBLR] sets the major and minor order of pagination.
rotate=90 sets landscape mode. (orientation=land is backward compati‐
ble but obsolete.)
center=n a non‐zero value centers the drawing on the page.
layers="id:id:id:id" is a sequence of layer identifiers for overlay
diagrams. The PostScript array variable layercolorseq sets the assign‐
ment of colors to layers. The least index is 1 and each element must be
a 3‐element array to be interpreted as a color coordinate.
color=colorvalue sets foreground color (bgcolor for background).
href="url" the default url for image map files; in PostScript files,
the base URL for all relative URLs, as recognized by Acrobat Distiller
3.0 and up.
URL="url" ("URL" is a synonym for "href".)
stylesheet="file.css" includes a reference to a stylesheet in -Tsvg and
-Tsvgz outputs. Ignored by other formats.
splines. If set to true, edges are drawn as splines. If set to poly‐
line, edges are drawn as polylines. If set to ortho, edges are drawn
as orthogonal polylines. In all of these cases, the nodes may not
overlap. If splines=false or splines=line, edges are drawn as line
segments. The default is false.
NODE ATTRIBUTES
height=d or width=d sets minimum height or width. Adding fixed‐
size=true forces these to be the actual size (text labels are ignored).
shape=record polygon epsf builtin_polygon
builtin_polygon is one of: plaintext ellipse oval circle egg triangle
box diamond trapezium parallelogram house hexagon octagon note tab
box3d component. (Polygons are defined or modified by the following
node attributes: regular, peripheries, sides, orientation, distortion
and skew.) epsf uses the node's shapefile attribute as the path name
of an external EPSF file to be automatically loaded for the node shape.
label=text where text may include escaped newlines \n, \l, or \r for
center, left, and right justified lines. The string '\N' value will be
replaced by the node name. The string '\G' value will be replaced by
the graph name. Record labels may contain recursive box lists delim‐
ited by { | }. Port identifiers in labels are set off by angle brack‐
ets < >. In the graph file, use colon (such as, node0:port28).
fontsize=n sets the label type size to n points.
fontname=name sets the label font family name.
color=colorvalue sets the outline color, and the default fill color if
style=filled and fillcolor is not specified.
fillcolor=colorvalue sets the fill color when style=filled. If not
specified, the fillcolor when style=filled defaults to be the same as
the outline color.
fontcolor=colorvalue sets the label text color.
A colorvalue may be "h,s,v" (hue, saturation, brightness) floating
point numbers between 0 and 1, or an X11 color name such as white black
red green blue yellow magenta cyan or burlywood, or a "#rrggbb" (red,
green, blue, 2 hex characters each) value.
style=filled solid dashed dotted bold invis or any Postscript code.
layer=id or id:id or "all" sets the node's active layers. The empty
string means no layers (invisible).
The following attributes apply only to polygon shape nodes:
regular=n if n is non‐zero then the polygon is made regular, i.e. sym‐
metric about the x and y axis, otherwise the polygon takes on the
aspect ratio of the label. builtin_polygons that are not already regu‐
lar are made regular by this attribute. builtin_polygons that are
already regular are not affected (i.e. they cannot be made asymmet‐
ric).
peripheries=n sets the number of periphery lines drawn around the poly‐
gon. This value supersedes the number of periphery lines of
builtin_polygons.
sides=n sets the number of sides to the polygon. n<3 results in an
ellipse. This attribute is ignored by builtin_polygons.
orientation=f sets the orientation of the first apex of the polygon
counterclockwise from the vertical, in degrees. f may be a floating
point number. The orientation of labels is not affected by this
attribute. This attribute is added to the initial orientation of
builtin_polygons.
distortion=f sets the amount of broadening of the top and narrowing of
the bottom of the polygon (relative to its orientation). Floating
point values between -1 and +1 are suggested. This attribute is
ignored by builtin_polygons.
skew=f sets the amount of right‐displacement of the top and left‐dis‐
placement of the bottom of the polygon (relative to its orientation).
Floating point values between -1 and +1 are suggested. This attribute
is ignored by builtin_polygons.
href="url" sets the url for the node in imagemap, PostScript and SVG
files. The substrings '\N' and '\G' are substituted in the same manner
as for the node label attribute. Additionally the substring '\L' is
substituted with the node label string.
URL="url" ("URL" is a synonym for "href".)
target="target" is a target string for client‐side imagemaps and SVG,
effective when nodes have a URL. The target string is used to deter‐
mine which window of the browser is used for the URL. Setting it to
"_graphviz" will open a new window if it doesn't already exist, or re‐
use it if it does. If the target string is empty, the default, then no
target attribute is included in the output. The substrings '\N' and
'\G' are substituted in the same manner as for the node label
attribute. Additionally the substring '\L' is substituted with the
node label string.
tooltip="tooltip" is a tooltip string for client‐side imagemaps and
SVG, effective when nodes have a URL. The tooltip string defaults to
be the same as the label string, but this attribute permits nodes with‐
out labels to still have tooltips thus permitting denser graphs. The
substrings '\N' and '\G' are substituted in the same manner as for the
node label attribute. Additionally the substring '\L' is substituted
with the node label string.
EDGE ATTRIBUTES
label=text where text may include escaped newlines \n, \l, or \r for
centered, left, or right justified lines. If the substring '\T' is
found in a label it will be replaced by the tail_node name. If the
substring '\H' is found in a label it will be replaced by the head_node
name. If the substring '\E' value is found in a label it will be
replaced by: tail_node_name->head_node_name If the substring '\G' is
found in a label it will be replaced by the graph name. or by:
tail_node_name--head_node_name for undirected graphs.
fontsize=n sets the label type size to n points.
fontname=name sets the label font family name.
fontcolor=colorvalue sets the label text color.
style=solid dashed dotted bold invis
color=colorvalue sets the line color for edges.
color=colorvaluelist a ':' separated list of colorvalue creates paral‐
lel edges, one edge for each color.
dir=forward back both none controls arrow direction.
tailclip,headclip=false disables endpoint shape clipping.
href="url" sets the url for the node in imagemap, PostScript and SVG
files. The substrings '\T', '\H', '\E' and '\G' are substituted in the
same manner as for the edge label attribute. Additionally the sub‐
string '\L' is substituted with the edge label string.
URL="url" ("URL" is a synonym for "href".)
target="target" is a target string for client‐side imagemaps and SVG,
effective when edges have a URL. If the target string is empty, the
default, then no target attribute is included in the output. The sub‐
strings '\T', '\H', '\E' and '\G' are substituted in the same manner as
for the edge label attribute. Additionally the substring '\L' is sub‐
stituted with the edge label string.
tooltip="tooltip" is a tooltip string for client‐side imagemaps effec‐
tive when edges have a URL. The tooltip string defaults to be the same
as the edge label string. The substrings '\T', '\H', '\E' and '\G' are
substituted in the same manner as for the edge label attribute. Addi‐
tionally the substring '\L' is substituted with the edge label string.
arrowhead,arrowtail=none, normal, inv, dot, odot, invdot, invodot, tee,
empty, invempty, open, halfopen, diamond, odiamond, box, obox, crow.
arrowsize (norm_length=10,norm_width=5,
inv_length=6,inv_width=7,dot_radius=2)
headlabel,taillabel=string for port labels. labelfontcolor,labelfont‐
name,labelfontsize for head and tail labels. The substrings '\T',
'\H', '\E' and '\G' are substituted in the same manner as for the edge
label attribute. Additionally the substring '\L' is substituted with
the edge label string.
headhref="url" sets the url for the head port in imagemap, PostScript
and SVG files. The substrings '\T', '\H', '\E' and '\G' are substi‐
tuted in the same manner as for the edge label attribute. Additionally
the substring '\L' is substituted with the edge label string.
headURL="url" ("headURL" is a synonym for "headhref".)
headtarget="headtarget" is a target string for client‐side imagemaps
and SVG, effective when edge heads have a URL. The headtarget string
is used to determine which window of the browser is used for the URL.
If the headtarget string is empty, the default, then headtarget
defaults to the same value as target for the edge. The substrings
'\T', '\H', '\E' and '\G' are substituted in the same manner as for the
edge label attribute. Additionally the substring '\L' is substituted
with the edge label string.
headtooltip="tooltip" is a tooltip string for client‐side imagemaps
effective when head ports have a URL. The tooltip string defaults to
be the same as the headlabel string. The substrings '\T', '\H', and
'\E' are substituted in the same manner as for the edge label
attribute. Additionally the substring '\L' is substituted with the
edge label string.
tailhref="url" sets the url for the tail port in imagemap, PostScript
and SVG files. The substrings '\T', '\H', '\E' and '\G' are substi‐
tuted in the same manner as for the edge label attribute. Additionally
the substring '\L' is substituted with the edge label string.
tailURL="url" ("tailURL" is a synonym for "tailhref".)
tailtarget="tailtarget" is a target string for client‐side imagemaps
and SVG, effective when edge tails have a URL. The tailtarget string
is used to determine which window of the browser is used for the URL.
If the tailtarget string is empty, the default, then tailtarget
defaults to the same value as target for the edge. The substrings
'\T', '\H', '\E' and '\G' are substituted in the same manner as for the
edge label attribute. Additionally the substring '\L' is substituted
with the edge label string.
tailtooltip="tooltip" is a tooltip string for client‐side imagemaps
effective when tail ports have a URL. The tooltip string defaults to
be the same as the taillabel string. The substrings '\T', '\H', '\E'
and '\G' are substituted in the same manner as for the edge label
attribute. Additionally the substring '\L' is substituted with the
edge label string.
labeldistance and port_label_distance set distance; also labelangle (in
degrees CCW)
decorate draws line from edge to label.
samehead,sametail aim edges having the same value to the same port,
using the average landing point.
layer=id or id:id or "all" sets the edge's active layers. The empty
string means no layers (invisible).
(neato‐specific attributes)
w=f sets the weight (spring constant) of an edge to the given floating
point value. The default is 1.0; greater values make the edge tend
more toward its optimal length.
len=f sets the optimal length of an edge. The default is 1.0.
COMMAND LINE OPTIONS-G sets a default graph attribute.

custom shapes or styles. If -l is given by itself, the standard
library is omitted.
-Tlang sets the output language as described above.
-O automatically generate output filenames based on the input filename
and the -T format.
-v (verbose) prints various information useful for debugging.
-V (version) prints version information and exits.
-? prints the usage and exits.
