发布时间:2023-02-22 10:51:21 来源:亿速云 阅读:142 作者:iii 栏目:开发技术

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:

    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:

    • 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])

    Matlab如何实现绘制有气泡感的网络图

    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();

    Matlab如何实现绘制有气泡感的网络图

    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)
