How do I color a scatterplot?

Hi!

I need to scatterplot the arrays x1,x2,y1,y2, in the following way:

scatter([x1;x2],[y1;y2])

how do I make it so that x1 and y1 have a different color than x2 and y2?

Thanks

Try this —

x1 = 1:10;
y1 = rand(size(x1));
x2 = 5:15;
y2 = rand(size(x2))+0.5;

figure
scatter(x1, y1, 50, 'dr', 'filled')
hold on
scatter(x2, y2, 50, 'sg', 'filled')
hold off
grid
legend('(x_1, y_1)','(x_2, y_2)', 'Location','best')

Experiment!
