How to add text or annotation in matlab subplots?

I have 12 scatter subplots, each for a particular year. I want to add 'year' and 'R-square value' in each subplot.

I tried 'text' but it is misplacing it. How to get it done? Here is my code,

i=1;
a=5;
step=0;
for year=2002:2013

      if mod(year,4)==0
          jump=366;
      else
          jump=365;
      end

      subplot(4,3,i)
      scatter(data_final(step+1:step+jump,11), data_final(step+1:step+jump,12),...
          a, 'filled', 'MarkerEdgeColor','b',...
          'MarkerFaceColor',[0 .7 .7],...
          'LineWidth',0.5)
      R=corrcoef(data_final(step+1:step+jump,11), data_final(step+1:step+jump,12));
      R=R(1,2)
      set(gca, 'FontName', 'Arial', 'FontSize', 12)

      ylim=get(gca,'ylim');
      xlim=get(gca,'xlim');
      text(xlim(1),ylim(2), num2str(year));

      xlabel('VAR_1') 
      ylabel('VAR_2') 
      grid on;

      title(num2str(year));

      i=i+1;
      step=step+jump;
  end

You should probably look at the text properties for HorizontalAlignment and VerticalAlignment
