绘制效果如下:

Matlab如何实现绘制有气泡感的网络图

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:

俩属性设置两种标签:

for i=1:100
    nodeName{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:

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:

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)
