You can just alter the PLOTYY function:

figure
x = 0:0.01:20;
y1 = 200*exp(-0.05*x).*sin(x);
y2 = 0.8*exp(-0.5*x).*sin(10*x);
[AX,H1,H2] = plotyy(x,y1,x,y2,'plot');
set(AX(2),'ytick',[-.7:.2:7])
set(AX,'yaxislocation','left')

Hi Matt, that's very good, so how to shift one of the axis to left more. we dont want them on top of eachother.and alosio, we dont want the right side y-axis
