三维散点图的Matlab实现

a=xlsread('数据.xlsx'); %H2 xh2=a(:,2); %X读取数据个数，不变动 yh2=a(:,1); %Y读取数据大类，1-5，此处为1 zh2=a(:,3); %Z读取具体数据， %CH4 xCH4=a(:,2); yCH4=a(:,5); %此处为2，E zCH4=a(:,6); %C2H6 xC2H6=a(:,2); yC2H6=a(:,8); %此处为3，H zC2H6=a(:,9); %C2H4 xC2H4=a(:,2); yC2H4=a(:,11);%此处为4，K zC2H4=a(:,9); %C2H2 xC2H2=a(:,2); yC2H2=a(:,14);%此处为5，N zC2H2=a(:,15); figure(1) scatter3(xh2,yh2,zh2,'k'); hold on scatter3(xCH4,yCH4,zCH4,'d'); hold on scatter3(xC2H6,yC2H6,zC2H6,'h'); hold on scatter3(xC2H4,yC2H4,zC2H4,'o'); hold on scatter3(xC2H2,yC2H2,zC2H2,'P'); hold on figure(2) plot(xh2,zh2);
