How can I selectively hold on and hold off plots in a polar plot

I have a for loop like this:

figure;
for i = 1:100

      p1 = polar(thetaOne(i),rOne(i),'r+')
      % *hold on* the above plot

      p2 = polar(thetaTwo(i),rTwo(i),'g+')
      % *hold off* the above plot

end

I have to retain the p1 and remove p2 from every iteration.

Suppose at i == 50, all the values thetaOne(1:50),rOne(1:50) must be there in the figure, and only thetaTwo(50),rTwo(50) must be present in the figure.

Then, you have to do this:

figure;
for i = 1:100
   for k=1:i
      p1 = polar(thetaOne(k),rOne(k),'r+')
      hold on
   end
      p2 = polar(thetaTwo(i),rTwo(i),'g+')
      hold off
end

If you read the documentation for hold you will find that the following syntaxes are permitted:

hold one
hold off
hold all
hold
hold(ax,'on')
hold(ax,'off')
hold(ax)

So you can supply the axes handle (using the function form), and it will control only that axis.
