How do I use multiple markers for multiple lines in a single graph?

What have you tried??? plot documentation has example, specifically named...

I tried following:

x = [0 : 300]

f = [0.015, 0.028, 0.054, 0.067, 0.08]

for i=1:length(f)

y = f*x;

plot(x,y,'-d','LineWidth',1, 'MarkerSize',5)

end

But this code will give only diamond marker in all the lines. I need different markers for different lines as per figure.

Try this:

x = [0 : 300];
f = [0.015, 0.028, 0.054, 0.067, 0.080];
markerIndexes = 1 : 30 : length(x);
markerShapes = {'d', 'o', 's', '^', 'v'};
for k = 1 : length(f)
    y = f(k) * x;
    % Plot solid line in blue.
    plot(x, y,'b-','LineWidth',1)
    hold on
    % Plot markers at subsampled points in red.
    hp(k) = plot(x(markerIndexes), y(markerIndexes), 'linestyle', 'none', 'Color', 'r', 'Marker', markerShapes{k}, 'MarkerSize',5);
    legendStrings{k} = sprintf('f = %.3f GHz', f(k));
end
grid on;
legend(hp, legendStrings, 'Location', 'northwest')
xlabel('x')
ylabel('y')

Thanks. I tried this with another code and it runs perfectly. Do you have any source or link so that I can learn more about this process?
