Bar width according to a duration type data in a bar graph

Hello everyone.

I have a bar graph which looks like this..

What I would like to do is modify this bar graph, so that each column gets a specific width according to a time interval (duration) that I have stored in a vector.

Other than that I wonder how can I insert a duration type vector in the x - axis of a bar graph, since what you see in this image are only xticks and xlabels of a specific istant of time of that duration time vector.

To sum up what I would like to obtain, is a bar graph like this, but on the x - axis there is a duration type data, and the column width corresponds to specific duration time intervals.

Thank you in advance, if I wasn't clear I can upload my code anytime.

x = 1:10;                   % x data
y = randi(10, size(x));     % y data
w = rand(size(x))/2;        % width
for i =1 : numel(x)
    bar(x(i), y(i), w(i), 'b');
    if i==1, hold on; end
end

Thanks for answering, I understand now how to obtain different widths, but how do I implement this in my code where w(i) should be a duration time array? I'm still getting trouble...
