MATLAB: Plotting a struct in a loop

loop

I have this code:
semilogy(S.A600(:,1),S.A600(:,2));
I also want to plot S.A601 up to S.A620
This does not work:
for i = 1:1:20
semilogy(S.A60(i)(:,1),S.A60(i)(:,2));
hold on
end
How can I loop through each one or do I have to manually type each plot command ?

Try this:
% S.A601 = rand(10, 2); % Create sample data.
% S.A602 = rand(10, 2);
% S.A603 = rand(10, 2);
% S.A604 = rand(10, 2);
% S.A605 = rand(10, 2);
% S.A606 = rand(10, 2);
fn = fieldnames(S)
for k = 1:length(fn)
  thisS = S.(fn{k})
  x = thisS(:, 1);
  y = thisS(:, 2);
  fprintf('Printing field #%d.\n', k);
  semilogy(x, y);
  hold on
  drawnow;
end
grid on;
