why in xticklabel not all x-axis label appear?

figure;
bar(sum(SM_MI)/length(SM_MI),'FaceColor', [0 0 0.6]);
hold on
bar(2,sum(SM_JD)/length(SM_JD),'FaceColor', [0 .6 .6]);
bar(3,sum(SM_JD_seg)/length(SM_MI),'y');
set(gca,'xticklabel',{'MI','J-div','j-div seg'});
barvalues(gca,'%.2f');
ylabel('Success rate')

I find the answer:

set(gca,'XTick',[1,2,3],'xticklabel',{'MI','J-div','j-div seg'});
