VertexLabels

VertexLabels
is an option and property for Graph and related functions that specifies what labels and label positions should be used for vertices.
MORE INFORMATION
  • The following option settings can be used:
Noneuse no vertex labels
Automaticautomatically label vertices
"Name"use the vertex name as a label
{v1->lbl1,v2->lbl2,...}label vertex with etc.
  • The wrapper Labeled is equivalent to Property and can be used when creating graphs in functions such as Graph etc.
  • Any expression can be used as a label.
  • Labeled and Placed can be used to place labels in relative position to the vertex box.
  • The following positions pos can be used for Labeled and Placed in positioning vertex labels:
Tooltip, StatusAreashow as tooltip or in status area on mouseover
Centerplace label at center of vertex
Before,After,Below,Aboveplace label outside before, after, etc.
Left,Right,Bottom,Topplace label inside to the left, right, etc.
{Before,Below},{After,Below},...place label outside at corner before/below, etc.
{Left,Bottom},{Right,Bottom},...place label inside at corner left/bottom, etc.
{{vx,vy},{lx,ly}}scaled position in the label at scaled position in the vertex

Basic Examples   (3)
Label individual vertices:
Label all vertices:
Use any expression as a label:
Label individual vertices:
In[1]:=
Click for copyable input
Out[1]=
 
Label all vertices:
In[1]:=
Click for copyable input
Out[1]=
 
Use any expression as a label:
In[1]:=
Click for copyable input
Out[1]=
Scope   (15)
Use vertex names as labels:
VertexLabels can be used for general graphs:
Matrix graphs:
Special graphs:
Random graphs:
Use VertexLabels in a Property wrapper:
Alternatively, use a Labeled wrapper:
Use Placed with symbolic locations to control label placement, including outside positions:
Symbolic outside corner positions:
Symbolic inside positions:
Symbolic inside corner positions:
Use explicit coordinates to place the center of labels:
Place all labels at the upper-right corner of the vertex and vary the coordinates within the label:
Place multiple labels using Placed in a wrapper:
Any number of labels can be used:
Place multiple labels using VertexLabels:
Use the third argument to Placed to control formatting including Tooltip:
Use more elaborate formatting functions:
