How to have multiple comet functions all in one graph?

Hi guys! I'm working on a school project but I am having trouble combining multiple comet functions into one graph. The assignment asks: A family with 10 kids is an ensemble – each child is unique and has its own “destiny”. You will have a family of simulations –each simulation will take 2,500 steps. Each simulation will have 2,500 steps. Start with X = 100. This is the code I have so far, but I am stuck on how to have create 10 unique multiple comets/graphs all fitted into 1 figure. I'm not sure if this is even possible, but I wanted the assignment to look clean. And if it is possible, how can I also incorporate a legend to identify which trail is which child? (I stopped the code at child 2 just to save space for this question-- but in my matlab it goes to 10)

%% System Clearing
clc;
clear all;
close all;
%% Walking/step Conditions
stepsL=1;   %stepping to the left
stepsR=1;   %stepping to the right
%% Individual Walking for-loop (CHILD 1)
for n = 100: 2500   % starting at 100
    x = rand ;
    if (x >= 0.5)
        stepsL = stepsL + 1; % if moving left
    else
        stepsR = stepsR + 1; % if moving right
    end
    location(n) = stepsL - stepsR; % location tracker for direction
end
comet(location)
title('Child 1')
xlabel('number of steps')
%% Individual Walking for-loop (CHILD 2)
for n = 100: 2500   % starting at 100
    x = rand ;
    if (x >= 0.5)
        stepsL = stepsL + 1; % if moving left
    else
        stepsR = stepsR + 1; % if moving right
    end
    location(n) = stepsL - stepsR; % location tracker for direction
end
comet(location)
title('Child 2')
xlabel('number of steps')

also, did I make it start at x=100 correctly? I'm not sure if I did it right-- I'm a beginner at MATLAB

th = linspace(0,2*pi,10^3) ; 
x0 = cos(th) ;
y0 = sin(th) ; 

x = th ;
y = [x0 ; y0] ; 

for i = 1:length(th)
  plot(x(1:i),y(:,1:i))
  axis([min(x) max(x) -1 1]) 
  drawnow
endfor

Do you mind explaining this? I don't quite understand.

Simple we are plotting it in a loop...and updating the lot.

What is "th" and where did you get those values for linspace? Also why are you using cos and sin?

I have taken it for demo....you should extend it for your case.
