Have you seen plotyy?
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');

I have created a 2D plot with 3 axis thanks to the plotyy command. Now I want to reformat all 3 axis: max, min limits and ticks for the axis. For the x axis and y principal axis I have been able with the basic commands but not for the 2nd Y axis. Any idea? Thank you in advance -Ferran
