How to plot a variable increasing in a for loop
显示 更早的评论
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.

do you want f1 vs F1 and f2 vs F1 on the same graph ?

Also, I would recommend taking the time to go through the online tutorial here: Matlab Onramp
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
