MATLAB: Plot multiple y-value on a single x-value

MATLABplotscatter

Hello,
I have array with two field (year and xx), for each year it has multiple y-value.
for exampel:
year = [2000 2001 2005 2008]
xx = [(5 10 20); (40 60); (30 20 10 50); (1)]
I am trying to plot scatter for each year (x-axis) all the coressponding values of xx (y-axis)
I was trying do it like this:
    dataplot = [];
    dataplot = [dataplot; year xx yy zz];
    [ay,~,cy] = unique(dataplot(:,1),'rows'); % to get just the unique year
    figure
    scatter(year,xx,'*');
        ax = gca;
    ax.XTick = 1:numel(ay);
    ax.XTickLabel = ay;
    ax.XLim = [0 numel(ay)+1];
also I tried the solution from (Q&A) after changing it but also I didn;t get what I want.
Please find the mat file of the array in the attachements, (PS just the first two fields).
Thanks in advance

Try this: 
year = [2000 2001 2005 2008];
xx = {[5 10 20]; [40 60]; [30 20 10 50]; 1};
figure
hold all
for k1 = 1:numel(year)
    plot(ones(1,numel(xx{k1}))*year(k1), xx{k1}, 'p')
end
hold off
It is necessary to put ‘xx’ in a cell array, since the vector lengths are different.
Experiment to get the result you want.
Plotting your actual data are even easier, since all the data are the same and each row has an associated year: 
D = load('dataplot.mat');
data = D.dataplot;
figure
plot(data(:,1), data(:,2:end)', 'p')
