Syntax

plot(G)

plot(G,LineSpec)

plot(___,Name,Value)

plot(ax,___)

h = plot(___)

Description

plot(G) plots the nodes and edges in graph G.

example

plot(G,LineSpec) sets the line style, marker symbol, and color. For example, plot(G,'-or') uses red circles for the nodes and red lines for the edges.

example

plot(___,Name,Value) uses additional options specified by one or more Name-Value pair arguments using any of the input argument combinations in previous syntaxes. For example, plot(G,'Layout','circle') plots a circular ring layout of the graph, and plot(G,'XData',X,'YData',Y,'ZData',Z) specifies the (X,Y,Z) coordinates of the graph nodes.

example

plot(ax,___) plots into the axes specified by ax instead of into the current axes (gca). The option, ax, can precede any of the input argument combinations in previous syntaxes.

h = plot(___) returns a GraphPlot object. Use this object to inspect and adjust the properties of the plotted graph.

`G` — Input graph
`graph` object | `digraph` object

Input graph, specified as either a graph or digraph object. Use graph to create an undirected graph or digraph to create a directed graph.

Example: G = graph(1,2)

Example: G = digraph([1 2],[2 3])

`LineSpec` — Line style, marker symbol, and color
character vector | string vector

Line style, marker symbol, and color, specified as a character vector or string vector of symbols. The symbols can appear in any order, and you can omit one or more of the characteristics. If you omit the line style, then the plot shows solid lines for the graph edges.

Example: '--or' uses red circle node markers and red dashed lines as edges.

Example: 'r*' uses red asterisk node markers and solid red lines as edges.

Line Style	Description	Resulting Line
`"-"`	Solid line
`"--"`	Dashed line
`":"`	Dotted line
`"-."`	Dash-dotted line

Marker	Description	Resulting Marker

`"blue"`	`"b"`	`[0 0 1]`
`"cyan"`	`"c"`	`[0 1 1]`

`ax` — Axes object
object

Axes object. If you do not specify an axes object, then plot uses the current axes (gca).

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: p = plot(G,'EdgeColor','r','NodeColor','k','LineStyle','--')

The graph properties listed here are only a subset. For a complete list, see GraphPlot Properties.

`ArrowSize` — Arrow size
positive value

Note

ArrowSize only affects the display of directed graphs created using digraph.

Arrow size, specified as the comma-separated pair consisting of 'ArrowSize' and a positive value in point units. The default value of ArrowSize is 7 for graphs with 100 or fewer nodes, and 4 for graphs with more than 100 nodes.

Example: 15

`EdgeCData` — Color data of edge lines
vector

Color data of edge lines, specified as the comma-separated pair consisting of 'EdgeCData' and a vector with length equal to the number of edges in the graph. The values in EdgeCData map linearly to the colors in the current colormap, resulting in different colors for each edge in the plotted graph.

`EdgeColor` — Edge color
`[0 0.4470 0.7410]` (default) | RGB triplet | hexadecimal color code | color name | matrix | `'flat'` | `'none'`

Edge color, specified as the comma-separated pair consisting of 'EdgeColor' and one of these values:

'none' — Edges are not drawn.
'flat' — Color of each edge depends on the value of EdgeCData.
matrix — Each row is an RGB triplet representing the color of one edge. The size of the matrix is numedges(G)-by-3.

RGB triplet, hexadecimal color code, or color name — Edges use the specified color.

RGB triplets and hexadecimal color codes are useful for specifying custom colors.

An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1]; for example,[0.4 0.6 0.7].
A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Thus, the color codes "#FF8800", "#ff8800", "#F80", and "#f80" are equivalent.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Color Name	Short Name	RGB Triplet	Hexadecimal Color Code
`"red"`	`"r"`	`[1 0 0]`	`"#FF0000"`
`"green"`	`"g"`	`[0 1 0]`	`"#00FF00"`

`"magenta"`	`"m"`	`[1 0 1]`	`"#FF00FF"`
`"yellow"`	`"y"`	`[1 1 0]`	`"#FFFF00"`
`"black"`	`"k"`	`[0 0 0]`	`"#000000"`
`"white"`	`"w"`	`[1 1 1]`	`"#FFFFFF"`

Here are the RGB triplets and hexadecimal color codes for the default colors MATLAB^® uses in many types of plots.
