Circular Graph Examples

Contents

1. Adjacency matrix of 1s and 0s

Create an example adjacency matrix made up of ones and zeros.

rng(0);
x = rand(50);
thresh = 0.93;
x(x >  thresh) = 1;
x(x <= thresh) = 0;

Call CIRCULARGRAPH with only the adjacency matrix as an argument.

circularGraph(x);

Click on a node to make the connections that emanate from it more visible or less visible. Click on the 'Show All' button to make all nodes and their connections visible. Click on the 'Hide All' button to make all nodes and their connections less visible.

2. Supply custom properties

Create an example adjacency matrix made up of various values and supply custom properties.

rng(0);
x = rand(20);
thresh = 0.93;
x(x >  thresh) = 1;
x(x <= thresh) = 0;
for i = 1:numel(x)
  if x(i) > 0
    x(i) = rand(1,1);
  end
end

Create custom node labels

myLabel = cell(length(x));
for i = 1:length(x)
  myLabel{i} = num2str(round(1000000*rand(1,1)));
end

Create custom colormap

figure;
myColorMap = lines(length(x));

circularGraph(x,'Colormap',myColorMap,'Label',myLabel);
