Hello, I am running a code within while loop(infinite) and need to plot the points in graph. Now the loops consists of a time stamp (t = t+1) and there is a reading called ESD(variable it is) and i am deriving it from some instrument. I want to plot them as real

time graph. as shown in the sample picture 1.png(but not 3 plots only one graph-that is just a sample). I am using the simple plot code to show it on graph but there it is plotting like this:

plot(t,ESD,'*') hold on grid on t =t+0.75;

So basically I want all the dots should be connected with the previous dot. Regards J

As you said you are using a loop.....try to save the result into an array and at the end plot them.

N = 1000 ;
count = 0 ;
A = zeros([],1) ;  % initialize the array to store point you want 
while count <= N
count = count+1 ;
A(count) = rand ;   % store the result 
end
plot(A)
