How to plot a variable increasing in a for loop

for F1 = 0.1:0.01:1
f1 = (F1*fs);
f2 = ((F1-0.001)*fs);
end
plot(f1,f2,"*-") %????
This currently brings a plot in the right scale but with only one point on it. Essentially i want every iteration of f1 and f2 as F1 increases to be plotted.

If the plot should be expanded in each iteration, move the plot command inside the loop:
axes('NextPlot', 'add'); % As hold('on')
for F1 = 0.1:0.01:1
f1 = F1 * fs;
f2 = (F1 - 0.001) * fs;
plot(f1, f2, "*")
end
A better option is to create vectors inside the loop:
F1 = 0.1:0.01:1;
for k = 1:numel(F1)
f1(k) = F1(k) * fs;
f2(k) = (F1(k) - 0.001) * fs;
end
plot(f1, f2, "*")
But you can even omit the loop:
F1 = 0.1:0.01:1;
f1 = F1 * fs;
f2 = (F1 - 0.001) * fs;
plot(f1, f2, "*")

Another option is to create an animatedline before the loop and addpoints to it inside the loop. Uncomment the pause statement or add some form of drawnow when running if you want to see the animation.
x = 0:360;
axis([0 360 -1 1])
hold on
h = animatedline;
for nextPoint = x
addpoints(h, nextPoint, sind(nextPoint))
% pause(0.01)
end
