Plotting separate points on the same graph while your program is running

Hi everyone,

I would like to find out if anyone knows how to plot points on a graph while the program is executing...

I have a for loop and each value of j gives me a different value of r. At the end of it, i would like to plot r (x-axis) against j (y-axis).

For example,

for j=1:5

%processes to find r..

r = %a certain value;

end

plot (r,j);

i cant seem to be able to get it done..

Try this code:

for j=1:5

%processes to find r..

r = %a certain value;
plot (r,j);
%plot must be inside the loop or you onlye get one value of j and r.
hold on 
%with this every new point adds to current graph instead of deleting it.

end

Hi Hector, one more thing, how do I draw a line through all the points?
