MATLAB: Boxplot – Size of the Labels

boxplotformat

Hi,

I am trying to use boxplot function by adjusting the size of the labels. Here is an example from Matlab:

load carsmall
boxplot(MPG,Origin)

Now, I want to increase the size of the labels. I found out that this can be done via the commands;

labelSize = 24; %size of the label
set(findobj(gca,'Type','text'),'FontSize',labelSize);

However, this results in the x-axis striking through the labels. Is there a way to increase the size of the labels in boxplot without making the x-axis strikethrough the labels?

Thanks in advance.

   set(findobj(gca,'Type','text'),'VerticalAlignment','top')

MATLAB: How to change text size in boxplot

I can think of two ugly hacks that work ...

The first is to set the default font size of all text labels for the plot

h = figure;
set(h, 'DefaultTextFontSize', 30);
load carsmall
boxplot(MPG, Origin);

The second is to change the text label after plotting

load carsmall
h = boxplot(MPG, Origin);
set(findobj(get(h(1), 'parent'), 'type', 'text'), 'fontsize', 30);

It is not clear to me what boxplot is actually returning. It is an array of handles, when I would have expect the group. My guess is if you look through the code of boxplot you can find a cleaner way.

EDIT

If you only have the figure file

hFig = figure;
load carsmall
boxplot(MPG, Origin);
saveas(hFig, 'temp_figure');
close(hFig);

You can open the figure and get the handle to the figure

hFig = open('temp_figure.fig');

The goal is then to find the boxplot object. Unfortunately, the boxplot object this is just an hggroup object and there might be lots of hggroup objects which are not boxplot objects. I don't know how to figure out if an hggroup object is actually a boxplot object. You can however, click around and select objects until gco works:

set(findobj(get(gco, 'Children'), 'type', 'text'), 'fontsize', 30);

MATLAB: Label multiple boxplots in same figure

As you didnot provided the K and M, so I did not able to cehck my code, this is perfectly works on bar charts, please try and let me know, it working or not?

x_label= {'HC';'SZ'};
toget=[K M];
grp=[zeros(1,21),ones(1,19)];
boxplot(toget,grp)
set(gca,'xticklabel',x_label)

boxplot([toget,grp],'Labels',{'HC','SZ'})
