# Running three different cases in my function and plotting three graphs on one plot (figure)

Hello,
I have three different cases inside my function. I run one of them while commenting out the other two and get one plot for it, after that I do the same thing for the other two. How can I run the three cases at once and plot the three graphs on one plot so it's easier to compare them?
I currently run my function three times, one time for monotonic case and get it's plot, and second time for anti monotonic and lastly random.
%Monotonic
[~, ina] = sort(A, 'descend');
[~, inb] = sort(B, 'descend');
%Anti Monotonic
% [~, ina] = sort(A, 'ascend');
% [~, inb] = sort(B, 'descend');
%Random
% ina=randperm(N,N);
% inb=randperm(N,N);

Asaf - try using hold to retain the current plot when adding new plots. For example,
x = -2*pi:0.01:2*pi;
plot(x, sin(x));
hold on; % <--- retain the current (and all future) plots
plot(x, cos(x));
plot(x, tan(x));
