Every 1,5,9,13..... marker point should be of same color. Similarly 2,6,10...... and 3,7,11...... and 4,9,12.... should be of same color

As shown in the plot below. I need the marker color of [1,5,9,13........] of same color. Similarly [2,6,10,.....] for e.g., green; [3,7,11......] for e.g blue; [4,9,12...] for e.g. magenta.

Thanks ,

Try something like this:

len = 1000; % dataset length
x = linspace(0,10,len);
y = exp(x/10).*sin(4*x);

colors=[1 0 0; ...
        0 1 0; ...
        0 0 1; ...
        1 1 0];

clf; 
plot(x,y); hold on;
ncolors=size(colors,1);
for p=1:ncolors
    plot(x,y,'o','MarkerSize',8,...
    'MarkerEdgeColor','red',...
    'MarkerFaceColor',colors(p,:),...
    'MarkerIndices',p:ncolors:len)
end

This requires a relatively recent version. I'm not sure of the exact version, but the 'markerindices' property isn't a thing in R2015b at least.

x = 1:100;
y = rand(1, 100);
colorPool = [1,0,0; 0,1,0; 0,0,1; 1,0,1];

figure;
axes('NextPlot', 'add');  % Equivalently to: hold('on')
plot(x, y, 'b-');
for k = 1:4
    ind = k:4:100;
    plot(x(ind), y(ind), 'o', 'MarkerEdgeColor', colorPool(k, :));
end

This also works! Thanks very much!!
