Dear all, I need to put labels under each boxplot. To do this, I'm using: boxplot([dados(:,1),dados(:,2)],'labels',{'bf\it{IDEB}_2_0_0_7'},{'\bfEfficiencies'}) Unfortunately, I don´t have sucess. Can someone help me? Best regards. Marcus Vinicius

When you say you don't have success, I assume you're saying that the labels aren't being rendered with the bold/italics/subscript formatting.
Try this:
dados = rand(100,2);
boxplot(dados,'labels',{'\bf\it{IDEB}_2_0_0_7','\bf Efficiencies'})
h = findobj(gca, 'type', 'text');
set(h, 'Interpreter', 'tex');

Hi, I kinda have the same problem. And your solution jiro does not work for me (MATLAB R2017a)!
Why? How can I make it work?
Why is there no proper handle for the boxplot function like for any other plot function?!

Dear Oleg, Thanks you very much for your attention. But, unfortunately, the labels aren't being rendered with the bold/italics/subscript formatting. Best wishes, Marcus Vinicius

Dear Jiro, Thanks you very much for your attention. How do I do so that the name IDEB_2007 does not sit so close to the x-axis? Best wishes, Marcus Vinicius

set boxplot labels bold and font size of 16...

This page helped solve my issues using boxplots. I will list out all the tweaks I wanted done to my boxplot in case it helps anyone else.
I found all the editable properties using:
h = findobj(gca, 'type', 'text');
and so on.
Here is an example of my tweaks:
data = rand(100,1); %random data
% a label for each data point
labels = repmat({'group2','group3','group1','group3'}',25,1);
Label_size = 15;
%used grouporder to arange the order of the boxes
%the labels option let you rename the labels (from group1 to G1)
title('Nice Boxplot','FontSize',Label_size,'FontWeight','bold')
h = findobj(gca, 'type', 'text');
% this alters Yticklabels [0 to 1]
% this alters the group labels: G1, G2, G3
% this moves the groups labels and the Xlabel down to avoid overlap
for j=1:length(h)
set(h(j),'Position',get(h(j),'Position')+[0 -5 0]);
h2 = get(gca, 'XLabel');
set(h2,'Position',get(h2,'Position')+[0 -8 0]);
You can change almost anything about any of the text this way, just look up the text properties you want to change, for more information see: text-properties.
