Graph Attributes

Where possible, GraphRecipes will adopt attributes from Plots.jl to format visualizations. For example, the linewidth attribute from Plots.jl has the same effect in GraphRecipes. In order to give the user control over the layout of the graph visualization, GraphRecipes provides a number of keyword arguments (attributes). Here we describe those attributes alongside their default values.

Attribute	Aliases	Default	Description
dim		2	The number of dimensions in the visualization.
T		Float64	The data type for the coordinates of the graph nodes.
curves		true	Whether or not edges are curved. If `curves == true`, then the edge going from node $s$ to node $d$ will be defined by a cubic spline passing through three points: (i) node $s$, (ii) a point `p` that is distance `curvature_scalar` from the average of node $s$ and node $d$ and (iii) node $d$.
curvature_scalar	curvaturescalar, curvature	0.05	A scalar that defines how much edges curve, see `curves` for more explanation.
root		:top	For displaying trees, choose from `:top`, `:bottom`, `:left`, `:right`. If you choose `:top`, then the tree will be plotted from the top down.
node_weights	nodeweights	nothing	The weight of the nodes given by a list of numbers. If `node_weights != nothing`, then the size of the nodes will be scaled by the `node_weights` vector.
names		[]	Names of the nodes given by a list of objects that can be parsed into strings. If the list is smaller than the number of nodes, then GraphRecipes will cycle around the list.
fontsize		7	Font size for the node labels and the edge labels.
nodeshape	node_shape	:hexagon	Shape of the nodes, choose from `:hexagon`, `:circle`, `:ellipse`, `:rect` or `:rectangle`.
nodesize	node_size	0.1	The size of nodes in the plot coordinates. Note that if `names` is not empty, then nodes will be scaled to fit the labels inside them.
nodecolor	marker_color	1	The color of the nodes. If `nodecolor` is an integer, then it will be taken from the current color pallette. Otherwise, the user can pass any color that would be recognised by the Plots `color` attribute.
x, y, z	x	nothing	The coordinates of the nodes.
method		:stress	The method that GraphRecipes uses to produce an optimal layout, choose from `:spectral`, `:sfdp`, `:circular`, `:shell`, `:stress`, `:spring`, `:tree`, `:buchheim`, `:arcdiagram` or `:chorddiagram`. See [NetworkLayout](https://github.com/JuliaGraphs/NetworkLayout.jl) for further details.
func		get(_graph_funcs, method, by_axis_local_stress_graph)	A layout algorithm that can be passed in by the user.
shorten	shorten_edge	0.0	An amount to shorten edges by.
axis_buffer	axisbuffer	0.2	Increase the `xlims` and `ylims`/`zlims` of the plot. Can be useful if part of the graph sits outside of the default view.
layout_kw		Dict{Symbol,Any}()	A list of keywords to be passed to the layout algorithm, see [NetworkLayout](https://github.com/JuliaGraphs/NetworkLayout.jl) for a list of keyword arguments for each algorithm.
edgewidth	edge_width, ew	(s, d, w) -> 1	The width of the edge going from $s$ to node $d$ with weight $w$.
edgelabel	edge_label, el	nothing	A dictionary of `(s, d) => label`, where `s` is an integer for the source node, `d` is an integer for the destiny node and `label` is the desired label for the given edge. Alternatively the user can pass a vector or a matrix describing the edge labels. If you use a vector or matrix, then either `missing`, `false`, `nothing`, `NaN` or `""` values will not be displayed. In the case of multigraphs, triples can be used to define edges.
edgelabel_offset	edgelabeloffset, elo	0.0	The distance between edge labels and edges.
self_edge_size	selfedgesize, ses	0.1	The size of self edges.
edge_label_box	edgelabelbox, edgelabel_box, elb	true	A box around edge labels that avoids intersections between edge labels and the edges that they are labeling.

Aliases

Certain keyword arguments have aliases, so GraphRecipes "does what you mean, not what you say".

So for example, nodeshape=:rect and node_shape=:rect are equivalent. To see the available aliases, type GraphRecipes.graph_aliases. If you are unhappy with the provided aliases, then you can add your own:

using GraphRecipes, Plots

push!(GraphRecipes.graph_aliases[:nodecolor],:nc)

# These two calls produce the same plot, modulo some randomness in the layout.
plot(graphplot([0 1; 0 0], nodecolor=:red), graphplot([0 1; 0 0], nc=:red))
