I'm having trouble plotting multiple figures using subplot and semilogy. Only the last figure appears in semilogy

h = figure(2);
for k = 1:length(T0)
    subplot(2,2,k);    
    semilogy(P0,squeeze(ploss(k,1,:)),'b');    
    str1 = strcat('\leftarrow', sprintf('max = %4.2f',max(massflow(k,1,:))));
    text(max(P0),max(squeeze(massflow(k,1,:))),str1);
    hold on;
    semilogy(P0,squeeze(ploss(k,2,:)),'r');
    hold off;
    str1 = strcat('\leftarrow', sprintf('max = %4.2f',max(massflow(k,2,:))));
    text(max(P0),max(squeeze(massflow(k,2,:))),str1);
      xlabel('Upstream Pressure Pa');
      ylabel('Pressure Loss %');
      title(sprintf('Valve Diameters and Pressure Loss, T0 = %d K',T0(k)));
      legend('8 in','10 in');
  end
