今天给大家带来一款用来绘制有气泡感的网络图的工具函数，绘制效果如下：

花里胡哨的，气泡大小代表流入流出数据量综合，不同颜色的气泡代表属于不同类，两个气泡之间有连线代表有数据流动，连线透明度代表流动数据量，连线的颜色是有方向性的渐变色。

依旧完整代码放在文末。

0 数据准备

数据需要的关系矩阵需要的是反对称矩阵：

% 随机生成100x100的反对角矩阵
Data=(rand(100)-.5).*(rand(100)>.978);
Data(1:30,:)=Data(1:30,:).*3;
Data=tril(Data)-tril(Data)';
% 生成100x1列向量，分类标签为1-10
Class=(1:10).*ones(10,1);
Class=Class(:);

1 基础绘图

两行代码完事：

% 基础绘图
BD=bubbleDigraph(Data,Class);
BD=BD.draw();

2 气泡大小

可以使用bubblesize函数设置气泡大小范围，例如：

bubblesize([5,40])

3 气泡颜色

使用setBubbleColor函数设置颜色：

BD.setBubbleColor(turbo(10))

4 气泡其他属性

可以使用setBubble函数进行设置，bubblechart图形对象具有的属性均可以修改：

BD.setBubble('MarkerFaceAlpha',.2,'MarkerEdgeColor',[0,0,0])

5 连线配色

直接使用colormap函数即可设置：

colormap(bone)

6 添加节点及类标签

分别使用：

• NodeName
• ClassName

俩属性设置两种标签：

for i=1:100nodeName{i}=[num2str(Class(i)),'-',num2str(i)];
end
className={'AAAAA','BBBBB','CCCCC','DDDDD','EEEEE','FFFFF','GGGGG','HHHHH','IIIII','JJJJJ'};BD=bubbleDigraph(Data,Class,'NodeName',nodeName,'ClassName',className);
BD=BD.draw();bubblesize([5,25])

7 标签距离

分别通过：

• RNode
• RClass

俩属性设置两种标签距离中心的距离：

BD=bubbleDigraph(Data,Class,'NodeName',nodeName,'ClassName',className,'RClass',1.38,'RNode',1.2);
BD=BD.draw();

8 设置字体

分别使用：

• setNodeLabel
• setClassLabel

俩函数设置两种标签的属性：

BD.setNodeLabel('FontName','Cambria','Color',[0,0,.8])
BD.setClassLabel('FontName','Cambria','Color',[.8,0,0],'FontSize',14)
