have to plot the number of head in a game of head or tails that the token is trowed N times, but my plot dont work

the plot has to show the number of faces per time the token is throwed

N = input('Coloque um valor para N: ');

cara = 0;

coroa = 0;

x=rand(1,N);

for i = 1:length(x)

if x(i) < 0.5

x(i) = 0; % cara

else

x(i) = 1; % coroa

end

end

figure

histogram(x);

title('Gráfico')

for i = 1: length(x)

if x(i) == 0

caras = cara + 1;

else

coroa = coroa + 1;

end

end

plot(cara , length(x))

% caras = cara + 1;
cara = cara + 1;

That will get the total number of heads (a.k.a. faces) to be correct, but you'll still be plotting only one point (which won't show up without a data marker).

To plot the number of heads vs the number of token throws (a.k.a. coin tosses a.k.a. coin flips) for the entire sequence of flips:

plot(cumsum(x==0))
