BUILT-IN MATHEMATICA SYMBOL

SetProperty

sets the property

for item in obj.

MORE INFORMATION

Properties are used to store and manipulate pairs for specific named items within an object such as Graph.

SetProperty will produce a new graph with a modified property value.

The items available for Graph objects include vertices and edges.

EXAMPLES

CLOSE ALL

Basic Examples (2)

Specify a vertex or edge property:

Use SetProperty to override the vertex style:

Specify a vertex or edge property:

In[1]:=

Out[1]=

In[2]:=

Out[2]=

Use SetProperty to override the vertex style:

In[1]:=

Out[1]=

In[2]:=

Out[2]=

In[3]:=

Out[3]=

Scope (6)

Set properties for vertices:

And edges:

Set several properties for a vertex:

And for an edge:

Standard vertex properties include VertexStyle:

Non-visual properties include VertexWeight:

Set a custom property:

Standard edge properties include EdgeStyle:

EdgeLabels:

EdgeShapeFunction:

Non-visual properties include EdgeWeight:

Set a custom property:

Applications (3)

Use Fold to apply SetProperty repeatedly:

See all the partial results:

Create a graph:

Temporarily highlight one vertex:

Then another:

Highlight the edges visited during a breadth-first scan:

Properties & Relations (6)

Use Property as a wrapper to specify properties in functions such as Graph:

Use PropertyValue to extract values:

For undefined properties the value $Failed is returned:

Use PropertyValue to set properties in a graph:

The original graph has changed:

Use PropertyValue to unset properties in a graph:

The original graph has changed:

Use PropertyList to test for the presence of a property:

Generate a list of vertex label rules:

Use RemoveProperty to remove a property without changing the original:

The original graph is unchanged:

Possible Issues (1)

PropertyValue is typically faster than SetProperty:
