I have four different plots in a single figure, the problem what I get is in the legend four of them assigned by the same color which I don't want and not correct, the plots are in different colors though. please If someone can help me on how to solve this problem. To make clear you can look the peace of code.
b=2;s=3;
plot(tt,Detection_2(:,1,1),'rs','Linewidth',2,'MarkerSize',8);hold on;
plot(tt,Detection_3(:,1,1),'y+','Linewidth',2,'MarkerSize',8);hold on;
plot(tt,Detection_4(:,1,1),'gs','Linewidth',2,'MarkerSize',8);hold on;
plot(tt,Detection_5(:,1,1),'m+','Linewidth',2,'MarkerSize',8);
l=legend('2-Targets','3-Targets','4-Targets','5-Targets');
set(gca,'FontSize',12);
grid MINOR
set(x,'Interpreter','latex','FontSize',12);
set(y,'Interpreter','latex','FontSize',12);
set(l,'Interpreter','latex','FontSize',12,'Location','southwest');
pbaspect([1 1 1])
set(gcf, 'Color', 'w');

That could happen if tt is a 2D array with at least 4 columns, as that would trigger the first plot() call to create one line for every column of tt. (Side note: it might be rows that is the problem instead of columns: plot() will automatically match the dimension of tt with the dimension of Detection_2(:,1,1) )
