draw a graph stored in the Graph data structure
list or set of graphs
(optional) zero or more options as specified below
The options argument can contain one or more of the options shown below. In addition, DrawGraph accepts those options listed on plot,options for 2-D visualizations and those options listed on plot3d,option for 3-D visualizations.
If the style=spring or style=spring[constant] option is specified then animate=true will cause a 50 frame animation of the model to be generated. The default is false.
dimension=2 or 3
The number of dimensions in the generated plot.
If the style=spring or style=spring[constant] option is specified then redraw=true will cause the graph to be redrawn using a different random starting position. The default is false.
If the style=tree drawing option is specified then G must be undirected or an arborescence per IsArborescence. If G is undirected and not a tree, its SpanningTree will be used to determine the location of its vertices, but all of the edges of G will be drawn. The additional optional argument root=v may be specified to specify the root vertex v. The value v must be a vertex in G.
The display of vertex labels may be forced or suppressed with the option showlabels=true and showlabels=false, respectively. By default, the vertex labels are displayed when G has fewer than 100 vertices.
The display of edge weights may be forced or suppressed with the option showweights=true and showweights=false, respectively. By default, the edge weights are displayed when G is a weighted graph with fewer than 46 edges.
style=bipartite, circle, planar, spring, spring[constant], or tree.
The style option directs DrawGraph to display the input graph in a specific style. There are five different styles supported for displaying a graph: bipartite, circle, planar, spring, and tree.
All components of a disconnected graph are detected and are displayed separately. The type of each graph or a component of a disconnected graph is distinguished and is displayed accordingly.
The style=spring option is so named because it simulates a physical model where the vertices are modeled as protons repelling each other and the edges are modeled as springs attracting adjacent vertices. This leads to a dense system of nonlinear ODEs to be solved and so this option becomes quite expensive beyond 100 vertices. At present the spring option requires that the graph be connected and it does not display edge weights in three dimensions.
The spring[constant] style uses a pure constant repulsive force for the vertices. This style is equivalent to spring for Maple 15 and earlier versions. The default is a combined model that initially integrates the ODE using a constant force model, then shifts to use of an inverse square law repulsive force.
The colors, line weights, and font choices can be specified with the stylesheet option which is detailed in GraphTheory/GraphDrawingOptions.
Specifying stylesheet="legacy" displays the graph with the default settings for Maple 2016 and previous versions. Animations and 3-D graph renderings currently do not support the stylesheet option.
DrawGraph displays the vertices and edges of a graph G as a Maple plot. If G has fewer than 100 vertices, the vertex labels are also displayed. If G is a weighted graph with fewer than 46 edges then the edge weights are displayed.
The colors, line weights, and font choices can be specified with the stylesheet option, detailed in GraphTheory/GraphDrawingOptions. Animations and 3-D graph renderings do not currently support the stylesheet option.
By default, the vertex positions for paths, cycles, cliques and most of the graphs in the SpecialGraphs, such as the Petersen graph, have been predefined, so that when displayed, they appear as they would in a textbook. You may specify the vertex positions for the display of a graph using the SetVertexPositions command.
You may set individual vertex and edge colors using the HighlightVertex and HighlightEdges commands. You may set vertex and edge colors of a subgraph of G using the HighlightSubgraph command, and set edge colors of a trail, path or cycle of G using the HighlightTrail command.
If G is a set or list of graphs, then the graphs are displayed in a Matrix format, where any leftover cells are simply displayed as empty. The number of graphs to display horizontally is chosen as a value between 2 and 4 determined by the number of graphs in the input list. This can be overridden by providing the width option to tell DrawGraph the number of graphs to display horizontally. For example, specify width=1 to display the graphs in one long vertical band, and specify width=nops(G) to display the graphs in one wide horizontal band.
