Boxplot Labels with more than one line

I am using the boxplot function to plot a grouped data set. I want the labels to have two lines: A name and the number of points (n).

for example:

%in a loop I set each label:
for i = 1:p
label2{i} = sprintf(label{i} '\n n = %d'], n(i))); 
end 

boxplot(data,G,'labels',char(label2{:})

The problem is that the label end up halfway above/below the xaxis line. I can use the findobj to get the text labels but not sure how to correct their position. I tried adding newlines in front of the labels but boxplot just ignored them. Any help?

I suppose a work around would be to make my own text labels for each box, but I think having them in the xlabel axis would be nice. I plan on making about 30 boxplot graphs like this so it would be nice to be able to do it programatically.
