I have 6 vectors and I want to make a plot of their areas, exactly like the image attached.

Is there any way to acomplished that? Thanks a lot!

Here's an example of the stacking area plots idea:
% Sample data
data = bsxfun(@plus, normpdf(linspace(0,6,100), 2, 0.5)', rand(100,6)*0.1);
data = bsxfun(@plus, data, rand(1,6)*0.5 + 0.25);
% Plot
n = size(data,2);
base = min(data) - 0.01; % Base value for each dataset
bloc = (0:n-1) * 0.5; % Where that base value will be located
axes; hold on;
for ii = 1:size(data,2)
h(ii) = area(data(:,ii)-base(ii)+bloc(ii), bloc(ii));
end
uistack(h, 'top');

You're right, 2014b+ versions seem to reset the base value for all area plots on an axis together, rather than allowing different ones per area object, as in previous versions. I'd submit a bug report on that... seems like an undocumented (and very inconvenient) change, at the least.

Answering my own question one year ago, this feature has not been fixed yet, meaning one baseline value for one axes. I end up assign every plot their own axes and hide everything for those axes.

I am facing the same issue, I solved it by using "Shade area between two curves" function by John Bockstege. The file exchange link for this function is below:
https://www.mathworks.com/matlabcentral/fileexchange/13188-shade-area-between-two-curves
It does not consider base value, but basically shades the area between two lines. So one line can be your vector and the other can be a baseline*ones(size(x)).
Hope this helps.
