Calling Sequence

HighlightTrail(G, T)

HighlightTrail(G, T, C, ip)

HighlightEdges(G, T, stylesheet=[ optionsequence ], ip)

Parameters

G

-

graph

T

-

a list of vertices (the trail) of G

C

-

(optional) color or list of colors

ip

-

(optional) equation of the form inplace = true or inplace = false

stylesheet

-

(optional) optionsequence is a sequence of keyword options to specify the style or a list of such sequences.

Description

• 

By default the DrawGraph command draws the edges and vertices of the graph with the same set of style options. The command HighlightTrail allows the trail to be given a different highlighted style specified in the graph stylesheet.

• 

Given only a graph G and an trail T, HighlightTrail marks the specified edges to be rendered with the default highlighted style.

• 

If you simply want a trail to have a different style, without being grouped with other highlighted graph components, use the command StyleEdge or StyleSubgraph instead.

• 

If you want to highlight a trail but give it a different color, the simplest way is to specify C, a color for the edges. The colors C can be given in any form understood by Maple. See ColorTools/Formats for details.

• 

If a list of colors or stylesheets is given, then they are used to associate a different color or style to each member of the trail.

• 

By default, this command modifies G and returns nothing. If you supply the option inplace = false, then instead the changes are applied to a copy of G, and that copy is returned.

• 

More precise overriding of the highlighted style can be set using stylesheet options. The stylesheet options are understood as modifiers to the default highlighted style. So, for example, if a color is not specified the default highlighted color is used. If the stylesheet option and a color C are both given, the color C is ignored. See StyleEdge for a complete list of edge style options.
