Plot in real time

i have a code that i wrote to perform an output of simple harmonic function. and when i plot the result in realtime (as is it going through the for loop) rather than plotting y versus time, it is plotting two point (1,time) and (2,y) and draws a line in between.

any help is appreciated as i am new at using matlab

clf;
A=3.3;
W=6.28;
time=0;
p=0;
for t = (0:0.01:2)
  y=A*sin(W*t);
  time = time +0.01;
  p=[time,y];
  graph=plot(p);
  drawnow;
  p
  pause(0.1)
end

Dear Jerry try this:

A = 3.3;
W = 6.28;
for t = 0:0.01:2
y = A * sin(W * t);
plot(t, y, 'g*'), hold on
drawnow;
pause(0.1)
end

I hope it helps. Good luck!

you are a genius, it worked, can you please tell me about the 'hold on' and explain to me why my original script did not work?

[Jerry]

how do make to be a line between the points?

the 'hold on' command holds the current plot and then plots new data on the same graph without overwriting it. Secondly, in ur original you were plotting data wrongly
