MATLAB: plot in a loop

I've tried to do plot inside of a loop and it prints only the last plot.

How can i fix it?

I've tried to use hold on and drawnow after the plot definition but it didn't work.

This is my code: 

for t=1:5
  alive = Game(World , Generations, speed);
  plot(hplot2,1:Generations,alive);
end

If the function Game(World , Generations, speed) is a deterministic function - it gives the same output for every t. Therefore, every plot commands has exactly the same output and you cannot distinguish the first from the last plot.

Try plot a random series at each iteration (as in answer of shoelzer) and see if you see all 5 plots.

Additionally, you might want to use hold all instead of hold on: this way each plot will get a different color from the colormap.

you can also use figure(t) to have 5 different figures.

Since you are already passing the axes handle to plot, you only need to put something like pause(0.1) inside the loop, and your original source will work.

Sticking in a "figure" has always worked for me.

for t=1:5
    alive = Game(World , Generations, speed);
    figure;
    plot(hplot2,1:Generations,alive);
end

hold on should work. Try this:

figure
hplot2=gca;
hold on
for t=1:5
    alive = rand(1,Generations);
    plot(hplot2,1:Generations,alive);
end
