title: matlab plot different colors
body: <p>I have set of <strong>points</strong> <em>(matrix Nx1)</em> and <strong>groups</strong> for this points <em>(matrix Nx1)</em>. I want to plot this points (there is no problem, I do this like this: <code>plot(points, groups, 'o');</code>), but I'd like to set unique color for each group. How can I do this? Now I have only two groups (1,2).</p>
