How can I plot two curves with two different y-axis (placed at right and left) with one reverse-logarithmic x-axis? Something like this BUT with a reverse x-axis for both curves: 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,'semilogx'); Thanks!

The problem with this command is: it will just reverse (x,y1) set and not (x,y2) set.

The problem with this command is: it will just reverse (x,y1) set and not (x,y2) set. Are you sure? It worked for me. MATLAB version R2007b.

I am using R2009b and if I run the below lines: 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,'semilogx'); set(AX,'xdir','reverse'); It is working now!! What happened!!
