Plot markers with equal distance on a linear chart?

Hello everbody :) Please help me draw the following picture(I should plot the circle and star markers exactly like the picture)

Below is my code but I can't plot my desired chart:

x=[5.98,8.06,10.71];
y=[0,1,0];
plot(x,y);
hold on;
x1=[5.98,8.11,11.01];
y1=[0,1,0];
plot(x1,y1,'b--o');

Thanks in advance:)

You need to have so many x values to have markers continuously. For example:

x = 0:pi/10:2*pi;
y1 = sin(x);
y2 = sin(x-0.25);
y3 = sin(x-0.5);

figure
plot(x,y1,'g',x,y2,'b--o',x,y3,'c*')

In the above example, x has 21 values, so when this plot is generated you will see 21 markers. I hope this helps!
