Data.GraphViz.Attributes

There are almost 150 possible attributes available for Dot graphs, and it can be difficult to know which ones to use. This module provides helper functions for the most commonly used ones.

The complete list of all possible attributes can be found in Data.GraphViz.Attributes.Complete; it is possible to use both of these modules if you require specific extra attributes that are not provided here.

The definition of attributes

data Attribute

Attributes are used to customise the layout and design of Dot graphs. Care must be taken to ensure that the attribute you use is valid, as not all attributes can be used everywhere.

Creating labels

The following escape codes are available for labels (where applicable):

\N

Replace with the name of the node.

\G

Replace with the name of the graph (for node attributes) or the name of the graph or cluster, whichever is applicable (for graph, cluster and edge attributes).

\E

Replace with the name of the edge, formed by the two adjoining nodes and the edge type.

\T

Replace with the name of the node the edge is coming from.

\H

Replace with the name of the node the edge is going to.

\n

Centered newline.

\l

Left-justified newline.

\r

Right-justified newline.

toLabel :: Labellable a => a -> Attribute

Equivalent to Label . toLabelValue; the most common label Attribute.

textLabel :: Text -> Attribute

An alias for toLabel for use with the OverloadedStrings extension.

xLabel :: Labellable a => a -> Attribute

Create a label outside of a node/edge. Currently only in the Graphviz development branch (2.29.*).

xTextLabel :: Text -> Attribute

An alias for xLabel for use with the OverloadedStrings extension.

forceLabels :: Attribute

Force the positioning of xLabels, even when it will cause overlaps.

textLabelValue :: Text -> Label

An alias for toLabelValue for use with the OverloadedStrings extension.

class Labellable a where

A convenience class to make it easier to create labels. It is highly recommended that you make any other types that you wish to create labels from an instance of this class, preferably via the String or Text instances.

Minimal complete definition

Colors

The recommended way of dealing with colors in Dot graphs is to use the named X11Colors rather than explicitly specifying RGB, RGBA or HSV colors.

These functions also allow you to use SVG and Brewer colors, but X11 colors are generally preferable. If you wish to use SVG colors, either import this module hiding X11Color or import the SVG module qualified.

data X11Color

The X11 colors that Graphviz uses. Note that these are slightly different from the "normal" X11 colors used (e.g. the inclusion of Crimson). Graphviz's list of colors also duplicated almost all Gray colors with Grey ones; parsing of an X11Color which is specified using "grey" will succeed, even for those that don't have the duplicate spelling (e.g. DarkSlateGray1).

bgColor :: NamedColor nc => nc -> Attribute

Specify the background color of a graph or cluster. For clusters, if style filled is used, then fillColor will override it.

bgColors :: NamedColor nc => nc -> nc -> Attribute

As with bgColor, but add a second color to create a gradient effect. Requires Graphviz >= 2.29.0.

fillColor :: NamedColor nc => nc -> Attribute

Specify the fill color of a node, cluster or arrowhead. Requires style filled for nodes and clusters. For nodes and edges, if this isn't set then the color value is used instead; for clusters, bgColor is used.

fillColors :: NamedColor nc => nc -> nc -> Attribute

As with fillColor, but add a second color to create a gradient effect. Requires Graphviz >= 2.29.0.

fontColor :: NamedColor nc => nc -> Attribute

Specify the color of text.

penColor :: NamedColor nc => nc -> Attribute

Specify the color of the bounding box of a cluster.

color :: NamedColor nc => nc -> Attribute

The color attribute serves several purposes. As such care must be taken when using it, and it is preferable to use those alternatives that are available when they exist.

• The color of edges;
• The bounding color of nodes;
• The bounding color of clusters (i.e. equivalent to penColor);
• If the filled Style is set, then it defines the background color of nodes and clusters unless fillColor or bgColor respectively is set.

Stylistic attributes

Various stylistic attributes to customise how items are drawn. Unless specified otherwise, all Styles are available for nodes; those specified also can be used for edges and clusters.

penWidth :: Double -> Attribute

Specify the width of lines. Valid for clusters, nodes and edges.

gradientAngle :: Int -> Attribute

Specify the angle at which gradient fills are drawn; for use with bgColors and fillColors. Requires Graphviz >= 2.29.0.

rounded :: Style

Also available for clusters.

tapered :: Style

Only available for edges; creates a tapered edge between the two nodes. Requires Graphviz >= 2.29.0.

radial :: Style

Available for nodes, clusters and edges. When using gradientAngle, indicates that a radial gradient should be used. Requires Graphviz >= 2.29.0.
