I realized in both 2013a and 2013b that there seems to be a bug in the coloring in the semilogx function. Colors displayed in the legend are not even present in the plot itself and sometimes the order seems to be wrong. In any case it's not possible to say which color refers to which data. I tried solving this problem for some days now and I'm pretty desperate about it. It's the same result whether I call the function from a .m-file or directly from the command window. Any work around? That's the code I use
semilogx(f20,real(var20(:,8)), f40,real(var40(:,8)), f60, real(var60(:,8)),f80, real(var80(:,8)), f100, real(var100(:,8)))
legend('20','40','60', '80', '100')
The attached picture shows the disaster.
Thanks for your help!

I just tried an example in R2013b and it worked fine, but then I messed with it a bit and happened to get something very similar to what you're seeing. So try looking at the dimensions of your x variables, f60 in particular.
When I used a matrix for one of the x variables, it got messed up. Perhaps f60 is a matrix instead of a vector?
If that's not the issue, is there any way you can share your variables with us? (Or, at very least, size/type/etc)
