Hi COMM, How can I hold only one plot while updating the rest in a figure ? E.g. I want to keep (x,f) plot fixed , while keeping the current value for the animated plot

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

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

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
