Matlab实现绘制有气泡感的网络图
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总和,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。
教程部分
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=1:100
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:
- 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)
