%% Plot Categorical Pie Chart with Labels
% Plot a categorical pie chart without any offset slices and label the
% slices. When |X| is of data type |categorical| you must specify the 
% input argument |explode|. To specify
% labels without any offset slices, specify |explode| as an empty
% cell array, and |labels| as the labels.

X = categorical({'North','South','North','East','South','West'});
explode = {};
labels = {'E','N','S','W'};
pie(X,explode,labels)

% Now, offset a slice and label all slices.
X = categorical({'North','South','North','East','South','West'});
explode = {'West'};
labels = {'E','N','S','W'};
pie(X,explode,labels)
