matlab怎么画桑基图
时间: 2023-10-31 21:56:17 浏览: 223
Matlab中可以使用sangraph函数来绘制桑基图,以下是一个简单的示例代码:
```matlab
% 创建一个随机的桑基图数据
nodes = {'A', 'B', 'C', 'D', 'E', 'F'};
values = randi([10, 50], 6, 2);
% 绘制桑基图
sankey(nodes, values, 'FontSize', 12, 'LabelColor', 'k', 'Gap', 0.02);
```
这段代码会绘制一个包含6个节点的桑基图,节点之间的流量由随机生成的数据控制。
sangraph函数的具体用法可以参考Matlab官方文档:https://www.mathworks.com/help/releases/R2021a/graph-and-network-algorithms.html#buc2zgs-1-sankey.

在 MATLAB 中绘制桑基图(Sankey diagram),你可以使用 MathWorks 提供的 Sankey 函数库。以下是一个简单的示例代码:
```matlab
% 创建节点和连接的数据
nodes = {'A', 'B', 'C', 'D', 'E'}; % 节点名称
links = [1 2 100; 1 3 50; 2 3 30; 2 4 20; 3 4 10; 4 5 80]; % 连接关系和流量
% 绘制桑基图
figure;
sankey(nodes, links, 'LabelMode', 'node');
title('Sankey Diagram');
```
在上面的示例中,节点(nodes)是一个包含节点名称的单元格数组,连接关系和流量(links)是一个矩阵,每一行代表一个连接,包括起始节点、目标节点和流量。
你可以根据实际的数据和需求修改节点和连接的数据,以及调整其他绘图选项来定制你的桑基图。

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