matlab绘制桑基图代码

Sure! Here is an example code for creating a Sankey diagram in MATLAB:

% Sample data
source = {'A', 'A', 'B', 'B', 'C'};
target = {'B', 'C', 'D', 'E', 'F'};
value = [10, 20, 5, 15, 8];

% Create a digraph object
G = digraph(source, target, value);

% Create the Sankey diagram plot
figure;
p = plot(G, 'Layout','layered', 'EdgeLabel', G.Edges.Weight);

% Customize the node positions and labels
p.XData = [1 2 2 3 3];
p.YData = [3 4 2 5 1];
labels = {'A', 'B', 'C', 'D', 'E', 'F'};
p.NodeLabel = labels;

This code creates a simple Sankey diagram using a directed graph object (`digraph`) in MATLAB. You can customize the source nodes, target nodes, and their corresponding values as per your requirements. The `plot` function is used to create the diagram plot, and you can specify the layout and edge labels as needed. Finally, you can also customize the node positions and labels using the `XData`, `YData`, and `NodeLabel` properties of the plot object.

Please note that you may need to install additional toolboxes or libraries depending on your MATLAB version and configuration.
