MATLAB: How to plot label in multiple lines in matrix form

xlabel

I am testing different conditions and I want to plot conditions I am comparing in a matrix form like shown in the figure. Any ideas how I can do that? Any help is greatly appreciated.
So far I've only managed to put it in two lines, like in the second picture, using code:
% example:
x = 1:1:10;
y = rand(10,1);
txt = {'1 2', '1 3', '1 4', '1 5', '2 3', '2 4', '2 5', '3 4', '3 5','4 5'};
labels = cellfun(@(x) strrep(x,' ','\newline'),txt,'UniformOutput',false);
figure()
plot(x,y,'.','MarkerSize',50)
xticks(x)
xticklabels(labels)
xlim([0.5 10.5])

You only provide one space. How can Matlab know you sometimes mean multiple spaces?
Because of the structure your labels seem to have, I would suggest using
mini_fun=@(a,b) ...
    [repmat(' ',1,a-1) ...
    num2str(a) ...
    repmat(' ',1,b-a-1) ...
    num2str(b) ...
    repmat(' ',1,5-b)];
index1=[1 1 1 1 2 2 2 3 3 4];
index2=[2 3 4 5 3 4 5 4 5 5];
%or generate these two vectors with combnk
txt=cellfun(mini_fun,num2cell(index1),num2cell(index2),'uni',false);
