Pre-allocate a large array to load values into during the loop. At the end of the loop, you can plot them all at once. I added tMax to limit the while loop and give an initial size for m and n arrays.
N=input('The total number of particles in the system is:');n=N; %The number of particles on left side at start.
m=0; %The number of particls remaining on the right side of the system at start.
tMax = 10000; % Maximum number of periods before exiting loop
mArray = NaN(tMax,1); % Initialize array to store m values
nArray = NaN(tMax,1); % Initialize array to store n values
t=0;while m<N/2 && t<tMax t=t+1; %Time interval
r=rand; %Determines if a particle moves from left to right
if r<n/N %Moves particle left to right
n=n-1; m=m+1; elseif r>n/N %Moves particle right to left
n=n+1; m=m-1; end nArray(t) = n; mArray(t) = m;endmArray = mArray(1:t);nArray = nArray(1:t);plot([mArray,nArray]);legend({'m','n'});Hope this helps.
One approach is to add a handle to the plot call (note the semicolon at the end to prevent printing all of the handles to the Command Window):
hp = plot(eStart:eStep:eEnd, XIR(:,transientCut:T),'g*' ,eStart:eStep:eEnd, XiR(:,transientCut:T),'b.' ... ,eStart:eStep:eEnd, XIr(:,transientCut:T),'r.' ,eStart:eStep:eEnd, Xir(:,transientCut:T),'k.');then use the appropriate parts of it in the legend call:
legend(hp(1:201:end),'XIR','XiR','XIr','Xir')That appeared to work correctly when I ran it (in R2020a, Update 4). (There are 804 Line objects in the plot, so a step size of 201 will get the first instance of each one.)
