Line each iteration when plotting in a for loop

Hello,

I am trying to plot several loops for different values of a variable. When using "hold on" there is a line appearing in each iteration. I would like to have a plot without all those lines. This is the code:

 Fmat(t_index,:)=[t_index F];

 plot (Fmat (:,1), Fmat (:,2));
 drawnow 
 hold on

Thanks a lot in advance for your reply!

Why not get rid of "hold on"?

Because if I don't use it then it will plot only the last result of the iteration...

Ok, so what exactly do you want to plot, and what is plotted instead? What is the "line" that appears in each iteration? Without some more code this is hard to answer.

Ok, yes I understand it is difficult.

There is a "for loop" for some values N=2,3,4... for each N there is another "for loop" for the variable t_index. At the end I should have a plot (call it a line) for each value of N where in my x axis the values are those t_index of the second loop.

Actually I just solved it. I had to plot it after I ended the second for loop.

Thanks anyway!
