I have a bunch of papers using different calculaton methords. I want to graph along the x axis the year the paper was published and on the y have boxes sized corrasponding to the number of papers of a given type published in that year where each type is coloured seperatly like a stacked bar chart. I have tried all manour of things and the closest thing I have got is this using a stacked bar chart but this is basically roated 90degrees from what I want (year on the x and number on the y with coloured boxes indicating type:

Actually, it's not too bad to just make up something...not sure where and why you ran into difficulties without seeing what sort of things you did try, but--

METHODS=categorical(string(('A':'E').'));       % easier than typing in your categories
YEARS=[2001:2010].';                            % arbitrary years
n=randi(300,numel(YEARS),numel(METHODS));       % generate some numbers by year and method
hB=bar(YEARS,n.','stacked');                    % put on stacked bar by year
xlim(xlim+[1 -1]*0.6)                           % I think extra white space at ends is ugly...
legend(METHODS)                                 % add legend and labels
xlabel('Publication Year'),ylabel('Number Publications by Method')
