How to clear a particular figure and replace it with other

So I have got a curve f in green which I want to keep as it is. I have plot a blue circle over it. Now I want to clear this blue circle by keeping the green curve as it is and plot a new red circle over it. How should I do it?

clf
hold on
fplot(f,'g')
xlim([-1,3])
ylim([-2,2])
p1 = plot(0,0,'bo');

clf(p1,'reset')

p2 = plot(0,1,'ro');

%f true
  clf
hold all
fplot(f,'g')
xlim([-1,3])
ylim([-2,2])
f1 = figure
plot(0,0,'bo');
clf(f1,'reset')
plot(0,1,'ro');

Reset using figure handles

%if true
 hold on
fplot(x^3-3*x,'g')
xlim([-1,3])
ylim([-2,2])
p1 = plot(0,0,'bo');
p1.YData = []
p1.XData = [];
plot(0,1,'ro');

Try this one instead. Ignore previous one
