- To plot multiple sets of coordinates on the same set of axes, specify at least one of x or y as a matrix.
Why don't the markers have the correct color in the legend?

If you run this code you will understand what I mean by my question.
I would like that in the legend also the circles had the correct color, otherwise I would rather remove them altogether, leaving only the names.
A1 = randi(10, [5 5]);
B1 = randi(10, [5 5]);
A2 = randi(10, [5 5]);
B2 = randi(10, [5 5]);
scatter(A1,B1,'g');
hold on
grid on
scatter(A2,B2,'b');
title('TEST');
xlabel('X','FontSize',8,'FontWeight','bold');
ylabel('Y','FontSize',8','FontWeight','bold');
legend({'\color{green}G1','\color{blue}G2'},'Location','northwest');
savefig('./Figures/Test')

The problem is that each of your calls to scatter is creating five separate sets of data for a total of 10 sets. But, you only request the legend to be displayed for the first two.
From the documentation:
To illustrate what I mean, here is your example, but displaying the legend for all of the sets of data:
A1 = randi(10, [5 5]);
B1 = randi(10, [5 5]);
A2 = randi(10, [5 5]);
B2 = randi(10, [5 5]);
scatter(A1,B1,'g');
hold on
grid on
scatter(A2,B2,'b');
title('TEST');
xlabel('X','FontSize',8,'FontWeight','bold');
ylabel('Y','FontSize',8','FontWeight','bold');
legend
Depending on what you really are trying to do, you might just need to reshape or redefine your data as vectors instead of matrices.

A1 = randi(10, [5 5]);
B1 = randi(10, [5 5]);
A2 = randi(10, [5 5]);
B2 = randi(10, [5 5]);
h1=scatter(A1,B1,'g');
hold on
grid on
h2=scatter(A2,B2,'b');
title('TEST');
xlabel('X','FontSize',8,'FontWeight','bold');
ylabel('Y','FontSize',8','FontWeight','bold');
legend([h1(1),h2(1)],{'G1','G2'},'Location','northwest');

@Laura Gianolio, Do you mean to display legend with the empty markers but still having the text colored ii.e. green and blue ?
