figure('Name','frequency of reduced category response by groups');
h = bar(mean_resp_bygroup([3,4,2,1],:)); %mean_resp_bygroup is a 4-by-2 double matrix
h.YLabel = 'Reduced Category Response';
h.DisplayName = {'OR','XOR'}; %legend labels
h.XTickLabels = {'W','X','Y','Z'};
legend();
title('Frequency of Reduced category response');
I get this error message: Expected one output from a curly brace or dot indexing expression, but there were 2 results.
I suspect that has something to do with how the function bar works in the background. Anyone has any idea how to solve this issue?

Now I get this error:
Error setting property 'YLabel' of class 'Axes':
Value must be 'matlab.graphics.Graphics'.

because your data is 4x2, h is an 1x2 array so you can't use h.YLabel. Check the value of h
You have to use h(1).YLabel but then 'YLabel' is not a valid property

Sorry, I always forget the .String field :)
