How do I construct a line plot with markers having different colors?

I have two 5 x 1 vectors 'x' and 'y' containing the x and y locations of my points. I have a matrix 'col' which is 3 x 5 and contains the colors I want for the markers:

[0 0 1

0 1 0

1 0 0

1 0 1

0 1 1]

I am plotting the line using this command :

x = [1 2 3 4 5]; y = [2 4 3 2 6];
plot(x, y, '-ko', 'MarkerFaceColor', 'red')

How can I control the color of individual markers ?

You cannot achieve this with the 'plot' command as it does not offer the functionality to control styles for individual markers on a line plot.

However, you can use the 'scatter' function to control the color for individual markers and use the 'plot' command to overlay it with your line plot.

For example :

x = [1 2 3 4 5];
y = [2 4 3 2 6];
c = [ 0 0 1; 0 1 0; 1 0 0; 1 0 1; 0 1 1];
f = plot(x, y, '-')
hold on 
scatter(x,y, [], c, 'filled')
hold off
