show

Plot graph representation

Since R2023a

Syntax

show(graph)

show(graph,Parent=ax)

axHandle = show(___)

Description

show(graph) plots the graph representation.

show(graph,Parent=ax) specifies the axes on which to plot the graph representation.

axHandle = show(___) returns the axes handle of the graph representation plot, in addition to any combination of input arguments from previous syntaxes.

Examples

Create navGraph Object with State and Link Tables

Load data for states and links.

load navGraphData.mat

Create state and link tables.

stateTable = table(data.states,data.names,data.numLanes, ...
    VariableNames=["StateVector","Name","Lanes"]);
linkTable = table(data.links,data.linkWt,data.curvature, ...
    VariableNames=["EndStates","Weight","Curvature"]);

Create a navGraph object from the state and link tables.

graphObj = navGraph(stateTable,linkTable);

Create a deep copy of the navGraph object.

graph2 = copy(graphObj)

graph2 = 
  navGraph with properties:

           States: [8x3 table]
            Links: [7x3 table]
    LinkWeightFcn: @nav.algs.distanceEuclidean

Visualize the navGraph object.

show(graphObj)

Find the link IDs of two state pairs. The function returns the link ID for the state pair ["G","A"]. However, it returns 0 as the link ID for the state pair ["C","D"] as the link does not exist in the navGraph object.

linkIDS = findlink(navGraphObj,["G","A"; "C","D"])

linkIDS = 2×1

     5
     0

Input Arguments

graph — Graph object

navGraph object

Graph object, specified as a navGraph object.

Example: show(graph)

ax — Axes on which to plot graph representation

Axes object

Axes on which to plot the graph representation, specified as an Axes object.

Example: show(graph,Parent=ax)

Example: axHandle = show(graph,Parent=ax);

Output Arguments

axHandle — Axes handle of graph representation plot

Axes object

Axes handle of the graph representation plot, returned as an Axes object.
