Hello,

I am having some difficulty with my legend. I keep getting the following error: 'Subset must be a vector of graphics objects.'

My current code is:

figure;
    h1 = plot((conTime(1:15,[1:3,5:6,8:end])), conBw(1:15,[1:3,5:6,8:end])); hold on;
    h2 = plot((b9Time(1:15,3:end)), b9Bw(1:15,3:end)); hold on;
    set(h1, 'Color', 'r');
    set(h2, 'Color', 'b');
    xlabel('Time (days)', 'FontSize', 12);
    ylabel('Body Weight (g)', 'FontSize', 12);
    xlim([1,50]);
    xticks(0:5:50);
    legend([h1, h2], 'Control', 'Intervention', 'location', 'southeast', 'FontSize', 11);
    legend box off;
   

On the other hand, when I set my legend using the following code, both my 'Control' and 'Intervention' appear with red lines, rather than red and blue (as I have set them):

legend('Control', 'Intervention', 'location', 'southeast', 'FontSize', 11);

Your feedback is greatly appreciated.

Many thanks.
