Is this the correct way to use "hold on" in a for loop?

I am new to MATLAB and just trying to run a program for projection motion. I feel I am using the hold on and hold off in the correct way but I'm greeted with empty plot. Can someone please point out the mistake in the code?

You only need to hold on for the first plot call, right?

That is not the way I would do it.

Try this instead:

figure
hold on
for t = 1:5
    dx = ...
    dy = ...
    plot(dx, dy, 'g-')
end
hold off
grid

I tried your way but it didn't result in the plot either. I was able to do it by eliminating for loop but can't find a way when I have to use it.

I canot run images of code, only actual code, so I could not run what was posted.

If you are plotting points, do this instead, in the loop:

plot(x, y, 'p')

to plot the points as stars without connecting lines.
