这篇文章主要介绍“Matlab如何实现绘制有气泡感的网络图”,在日常操作中,相信很多人在Matlab如何实现绘制有气泡感的网络图问题上存在疑惑,小编查阅了各式资料,整理出简单好用的操作方法,希望对大家解答”Matlab如何实现绘制有气泡感的网络图”的疑惑有所帮助!接下来,请跟着小编一起来学习吧!
绘制效果如下:
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1-10Class=(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)];endclassName={'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)
工具函数完整代码
