Plot with different markers

[Xin Dong]

Hi all,

I wanna plot several data sets on the same figure and I want the marker for each line is different. According the manual, I write this:

 figure;
semilogx(freq, d(1, :), "address@hidden;\theta_s=1;");
hold on;
semilogx(freq, d(2, :), "address@hidden;\theta_s=5;");
hold on;
semilogx(freq, d(3, :), "address@hidden;\theta_s=10;");
hold on;
semilogx(freq, d(4, :), "address@hidden;\theta_s=20;");

However, the result is that the markers are the same ("+") but the colors are different.
How can I set different markers?

Cheers,
Xin
