MATLAB: Assigning Color to Plot of Same Variable

Question

So I am plotting the same variable 3 times within one figure that's parameters change with simulink. It produces 3 lines but the problem is, the 3 lines are the same color even though I specify each of the plots to be different linewidth, color and legend. It produces the very last specific color values.

I tried the following

plot(t,x, 'Color', 'Black', 'Linewidth', 2);
legend('Black');
hold on;
plot(t,x, 'Color', 'Cyan', 'Linewidth', 2);
legend('Cyan');
hold on;
plot(t,x, 'Color', 'Blue', 'Linewidth', 2);
legend('Blue');

All the lines on the graph show up as Blue even though I specified different colors/legend for each of the lines.

Answer 1

Try this

plot(t, x, 'k-', 'LineWidth', 2);
hold on;
plot(t, x, 'c-', 'LineWidth', 2);
plot(t, x, 'b-', 'LineWidth', 2);
legend('Black', 'Cyan', 'Blue');
