Stacked bar plot, assign "names" to color

How can I assign names to color? In the figure, say, in the right side list, I will assign "Jack's Contribution" to blue instead of "data 6".

Just add labels to your legend:

labels = { 'Jack', 'Fred', 'abc',  'def' }; % fill out, as desired
legend(labels);
