Matlab plotyy画2个纵坐标不同的图

PS：注意：AX返回的是两个坐标轴的句柄，而H1和H2则是表示的每个图像的句柄。

figure;

t=0:1:9*pi;

[H,Ha,Hb]=plotyy(t,sin(t),t,exp(t));

d1=get(H(1),'ylabel');

set(d1,'string','yayacpf');

d2=get(H(2),'ylabel');

set(d2,'string','bbs from hit','fontsize',18);

[var1]

t=0:0.1:9;

[ax,h1,h2]=plotyy(t,sin(t),t,cos(t));

set(h1,'linestyle','-','marker','o','color','r');

set(h2,'linestyle',':','marker','x','color','b');

[var1]

x=linspace(0,2*pi,50);

[ax,h1,h2]=plotyy(x,sin(x)+cos(x),x,exp(x));

set(h1,'linestyle','-')

set(h2,'linestyle','-')

set(h1,'marker','o')

set(h2,'marker','+')

hold on

x=linspace(0,2*pi,50);

hh=line(x,cos(x));

set(hh,'linestyle','-')

set(hh,'marker','s')

hold on

hhf=line(x,sin(x));

set(hhf,'color','r')

set(hhf,'linestyle','-')

set(hhf,'marker','*')

legend([h1,h2,hh,hhf],'sin(x)+cos(x)','exp(x)','cos(x)','sin(x)'); %加注图例
