I have plotted a circle with red dots using the sine and cosine functions , but I am trying to edit it such that every other dot color is blue. Here is my code

t=0:0.1:2*pi;

figure

hold on

for i=1:numel(t)

sine=sin(t);

cosine=cos(t);

end

plot(sine,cosine,'r.')

xlim([-1.25 1.25])

ylim([-1 1])

axis equal

All markers in a series will have the same color, so the best approach I can think of is to plot two separate series, one with red markers and the other with blue.

t=0:0.1:2*pi;

figure

sine=sin(t);

cosine=cos(t);

plot(sine(1:2:end),cosine(1:2:end),'r.')

hold on

plot(sine(2:2:end),cosine(2:2:end),'b.')

hold off

xlim([-1.25 1.25])

ylim([-1 1])

axis equal
