Try this (if you have R2014b or later):
y1 = [2 2 3; 2 5 6; 2 8 9; 2 11 12];
hBar = bar(y1,1); % Return ‘bar’ Handle
for k1 = 1:size(y1,2)
ctr(k1,:) = bsxfun(@plus, hBar(1).XData, hBar(k1).XOffset'); % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
ydt(k1,:) = hBar(k1).YData; % Individual Bar Heights
text(ctr(k1,:), ydt(k1,:), sprintfc('%.1f', ydt(k1,:)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom', 'FontSize',8, 'Color','b')
end
the sprintfc function is undocumented. It is essentially the same as sprintf, and augmented to produce a cell array of outputs. This makes it very efficient in situations such as this, where the result is a cell array.

if the vlaue is more than 4 then its not working
y1 = [0.433 0.177 0.768 1.224; 0.379 0.158 0.267 0.320; 0.0406 0.016 0.031 0.0380; 0.0972 0.0371 0.0538 0.0483; 0.0777 0.0324 0.0552 0.0660];
can you solve this?

It works correctly with your data when I run it here —
y1 = [0.433 0.177 0.768 1.224; 0.379 0.158 0.267 0.320; 0.0406 0.016 0.031 0.0380; 0.0972 0.0371 0.0538 0.0483; 0.0777 0.0324 0.0552 0.0660];
hBar = bar(y1,1); % Return ‘bar’ Handle
for k1 = 1:size(y1,2)
ctr(k1,:) = bsxfun(@plus, hBar(1).XData, hBar(k1).XOffset'); % Note: ‘XOffset’ Is An Undocumented Feature, This Selects The ‘bar’ Centres
ydt(k1,:) = hBar(k1).YData; % Individual Bar Heights
text(ctr(k1,:), ydt(k1,:), sprintfc('%.1f', ydt(k1,:)), 'HorizontalAlignment','center', 'VerticalAlignment','bottom', 'FontSize',8, 'Color','b')
end
.
