how to give equally align ylabel in subplot loop

This is one script to create subplots of some technique.

figure('Color',[1 1 1]) for i = 1:8

    pp=subplot(8,1,i);
    ax=get(pp,'Position');
ax(2)=ax(2)+0.015; %or wathever
set(pp,'Position',ax); 
plot(t(1:n),imf(i,:)) %%t(1:n) and imf(i,:) is being created in previous script which is not described
 set(gca,'ytick',[])
     set(gca,'xticklabel',[])
    set(gca,'ytickMode','auto','Fontname','Times new roman','FontSize',16,'fontweight','b')
    set(gca,'xtickMode','auto')
    set(gca,'XMinorTick','on','YMinorTick','off')

     xlim ([0 6.4])
    y_titre=sprintf('C%d',i); 

    ylabel(y_titre,'Fontname','Times new roman','FontSize',16,'fontweight','b')
    end   
     set(gca,'xticklabel',[0:1:6.4],'Fontname','Times new roman','FontSize',16,'fontweight','b')

      xlabel('Time(s)','Fontname','Times new roman','FontSize',24,'fontweight','b')

Now everything runs fine until this small problem in which IMF1 and IMF2 are not aligned with remaining IMFs.(click on above link to see the problem) Kindly help me to solve this problem so that everything on ylabel (such as IMF1, IMF2, IMF3, IMF4 etc.) are equally aligned.
