Change layout of graph plot
layout(
changes the layout of graph
plot H
)H
by using an automatic choice of layout method based on the
structure of the graph. The layout
function modifies the
XData
and YData
properties of
H
.
layout(
uses additional options specified by one or more name-value pair arguments. For
example, H
,method
,Name,Value
)layout(H,'force','Iterations',N)
specifies the number of
iterations to use in computing the force layout, and
layout(H,'layered','Sources',S)
uses a layered layout with
source nodes S
included in the first layer.
Use the Layout
name-value pair to change the layout of a
graph when you plot it. For example,
plot(G,'Layout','circle')
plots the graph
G
with a circular layout.
When using the 'force'
or 'force3'
layout methods, a best practice is to use more iterations with the algorithm
instead of using XStart
, YStart
, and
ZStart
to restart the algorithm using previous outputs.
The result of executing the algorithm with 100 iterations is different in
comparison to executing 50 iterations, and then restarting the algorithm from
the ending positions to execute 50 more iterations.
