How can I set x ticks for every curve in the subplot, legend for every curve and a title for the whole figure?

I have the following figure with 12 curves superimposed on each other, as shown below.

I want to draw each curve alone with a subplot as shown below

I would like to put for every curve legend from the ones in the first figure (i.e., the first curve 5, the second one 10, ..., till 60) and x ticks like the one in the first figure (16, 32, ..., 1024) and title for the whole figure.

My try below:

Q = [16,32,64,128,256,512,1024];
VEC_Beam_5 = [113.2659   69.7204   51.8739   34.5033   21.6538   10.9459    5.9488];   % Coverage area of Theta = 5

VEC_Beam_60 = [117.7870   76.6211   54.2534   38.7864   23.0815   13.5634    6.9007];  % Coverage area of Theta = 60

figure
cmap = jet(12);
hold on
for k = 1:12
    plot(log2(Q),VEC_Beam(k,:), 'Color', cmap(k, :),'LineWidth',2, 'Marker','O');
end
hold off
xticks(log2(Q))
xticklabels(string(Q))
xlabel('Q');
ylabel('Coverage area');
title('Beam');
legstr= "\theta_1_/_2 = "+(5:5:60)+"°";
legend(legstr)
grid on;

figure
cmap = jet(12);
hold on
for k1 = 1:12
    subplot(2,6,k1)
    plot(log2(Q),VEC_Beam(k1,:), 'Color', cmap(k1, :),'LineWidth',2, 'Marker','O');
    xticks(log2(Q))
    xlabel('Q');

    grid on;
    legstr= "\theta_1_/_2 = "+(5)+"°";
    legend(legstr)
end

It looks like it works just fine except for the legend.

Instead of

legstr= "\theta_1_/_2 = "+(5)+"°";

try this

legstr= "\theta_1_/_2 = " + (5 + 5*(k1-1)) + "°";

With that change I get this figure

As far as adding a title for the entire figure, I'm not sure how to do that unless you change to using tiledlayout instead of subplots. If you do that, you pass the handle to the tiledlayout to the title function.

@Les Beckham Thanks a lot dear. I accepted your answer. Regarding the title use this function

sgtitle('QAM 16');

[Les Beckham]

You are quite welcome. I had forgotten about sgtitle. Thanks for the reminder.
