Hi, I want to plot 4 y-axes against x-axis. I want to put legend and colour. How do I plot it? Thanks Isa

Something like plotyy but then with four y-axes? Can you draw an example?

Like x = linspace(0,5); y1 = sin(x); y2 = sin(5*x); y3= sin(10*x); y4=sin(15*x); Plot y1,y2,y3 and y4 against x

Answer 1

Another interpretation of your question results in this solution:

   x = linspace(0,2*pi); y1 = sin(x); y2 = sin(5*x); y3= sin(10*x); y4=sin(15*x);
plot(x,y1,'b',x,y2,'r',x,y3,'c',x,y4,'k')
legend({'sine of x','sine of 5x','sine of 10x','sine of 15x'})

Check out the excellent addaxis function by Harry Lee.

It let's you add n y-axes to any plot, plus has lots of extended functionality for redrawing, adding additional lines after plotting, etc, etc.
