circular bubble digraph

Circular bubble digraph for weighted directed graphs. Nodes on circle, edges as curved ribbons. Supports grouping, labels & colorbar.

Baisc usage

% Generate skew-symmetric adjacency matrix A(i,j) = -A(j,i)
Data = (rand(50) - 0.5) .* (rand(50) > 0.99);
Data = tril(Data) - tril(Data)';

% Generate random group IDs (1 to 5) for 50 nodes
ids = randi([1, 5], [1, 50]);

% Sort nodes by group ID for contiguous grouping
[ids, ind] = sort(ids);
Data = Data(ind, ind);

% Create node labels: 'N-1', 'N-2', ..., 'N-50'
labels = compose('N-%d', 1:50);

% Create circular bubble digraph object and draw
CBD = circBubbleDigraph(Data, 'Group', ids, 'NodeName', labels);
CBD.draw();

Data = (rand(50) - 0.5) .* (rand(50) > 0.99);
Data = tril(Data) - tril(Data)';

ids = randi([1, 5], [1, 50]);
[ids, ind] = sort(ids);
Data = Data(ind, ind);

labels = compose('N-%d', 1:50);

CBD = circBubbleDigraph(Data, 'Group', ids, 'NodeName', labels);

% Change node color
CBD.CData = lines(5);

CBD.draw();

% Set edge colormap to 'cool'
colormap(cool)
% Add colorbar
CB = CBD.colorbar;

Adding and adjusting node labels and group labels

Data = (rand(100) - .5).*(rand(100) > .995);
Data = tril(Data) - tril(Data)';

ids = randi([1, 10], [1, 100]);
[ids, ind] = sort(ids); 
Data = Data(ind, ind);

% Create labels: 'N-1' to 'N-100' for nodes, 'Group-A' to 'Group-J' for groups
nLabels = compose('N-%d', 1:100);
gLabels = compose('Group-%c', 'A':'J');
% Set custom properties
CBD.Group = ids;                % Group assignment for each node
CBD.NodeName = nLabels;         % Node labels
CBD.GroupName = gLabels;        % Group labels
CBD.NodeLabelRadius = 1.1;      % Distance of node labels from center
CBD.GroupLabelRadius = 1.3;     % Distance of group labels from center
CBD.Curvature = 0.8;            % Edge curvature (0 = straight, 1 = full Bezier)
CBD.draw();

CBD.setClassLabel('Color', [0,0,.8])
CBD.setNodeLabel('Color',[79,148,204]./255)
