SSmin=0;

SSmax=19;

x=SSmin:0.01:SSmax;

f= (x).*sin(x) +20;

figure

plot(x,f)

hold on

for k=1:length(x)

plot(x(k),f(k),'or')

axis([SSmin SSmax 0 30])

pause(0.2)

end

在 MATLAB Online 中打开

for k=1:length(x)
  plot(x(1:k),f(1:k),'or')
  axis([SSmin SSmax 0 30])
  pause(2)
end

Check with this

This is not working VBBV, Its just delaying the pause time

在 MATLAB Online 中打开

h = animatedline('MaximumPoints',length(x),'Marker','or')
for k=1:length(x)
  addpoints(h,x(k),f(k))
  axis([SSmin SSmax 0 35])
  drawnow
end

you can use drawnow to animate the line. Check also animate page for more information how to animate
