How can I change the values of a plot inside a loop?

Hi all,
I want to plot something and then change the values of some variables inside a loop without plotting everything again. I think something as 'handle' and 'set' would help but, honestly, I do no have any idea of how to use it. I am going to use real-time data, so I want to use quick functions, this is the reason because I don't want to plot again and just change the values inside a plot already defined. Something like that:
h=plot(x,y)
n=0;
while n<5
x=x+n;
y=y-n;
%%change the values of x and y in the previous plot%%
n=n+1;
end

You can set the 'xdata' and 'ydata' properties of the line. You may have to make sure you set your axis limits so they aren't reset as the data moves.
x = sort(rand(10,1));
y = rand(10,1);
h = plot(x,y);
set(gca, 'xlim', [0 20], 'ylim', [-10 1]);
n=0;
while n<5
x=x+n;
y=y-n;
n=n+1;
set(h, 'xdata', x, 'ydata', y);
pause(1);
end
