plotting multiple boxplots in the same figure window

I have 10 vectors of temperature data, all different lengths, that I want to make boxplots of and plot them all in the same figure window. How do I do this?

Here's how to do that with three vectors of different lengths:
x1 = rand(10,1); x2 = 2*rand(15,1); x3 = randn(30,1);
x = [x1;x2;x3];
g = [ones(size(x1)); 2*ones(size(x2)); 3*ones(size(x3))];
boxplot(x,g)

A = [16 20 15 17 22 19 17]';
B = [22 15 16 16 16 18]';
C = [23 9 15 18 13 27 17 14 16 15 21 19 17]';
group = [ ones(size(A)); 2 * ones(size(B)); 3 * ones(size(C))];
figure
boxplot([A; B; C],group)
set(gca,'XTickLabel',{'A','B','C'})

@Matt Learner Thank you for your answer. I was having the same problem. For the above example they it has only three variables (A, B,C), but what will happen if it has 1000 variables, are we going to type all in the group?
I ask any robest way to do this for longer data.

You would store the variables in a structure, where each field is a variable. Then you would loop through the fields, vertically concatenating each one.
e.g.
s.A = rand(10,1);
s.B = rand(15,1);
s.C = rand(20,1);
allData = [];
allCats = [];
allFields = string(fieldnames(s))
for iField = 1:length(allFields)
allData = [allData;s.(allFields(iField))];
allCats = [allCats,repelem(allFields(iField),length(s.(allFields(iField))));]
end
boxplot(allData,allCats)

Are you familiar with the SUBPLOT function? This may be what you are looking for…
