n=input('Enter a natural number');
cont=1:1:n;
while n>1
if rem(n,2)==0
n=n/2;
elseif rem(n,2)~=0
n=n*3+1;
end
plot(cont,n,'--rs');
end

Something like this? Not quite sure what you want your x-axis to be.
n = input('Enter a natural number');
cont=1:1:n;
ii = 0;
while n>1
ii = ii + 1;
if rem(n(ii),2)==0
n(ii+1) = n(ii)/2;
elseif rem(n(ii),2)~=0
n(ii+1) = n(ii)*3+1;
end
end
plot(ii,n,'--rs');

% i used hold on and in the plot only appears the points because hold on is used to unite different % plots in one, so i guess that im unable to create a line to connect the points.
n=input('Enter a natural number');
cont=1;
while n>=1
plot(cont,n,'rs','LineWidth',2,'MarkerSize',10);
if n==1
n=1;break
elseif rem(n,2)==0
n=n/2;
elseif rem(n,2)~=0
n=n*3+1;
end
hold on cont=cont+1; end

jonathan, have you checked out/run the code that I posted above?
My second post contains another way of plotting the data you might want to try.
