Plotting a figure with bars in stack

Hi,

I want to plot a figure in which I have two columns of number in increasing order and I want them to plotted like an image attached here. I have no idea how I can do this. The two columns of these bars are columns of number and each number is replaced by a bar.

Any number of ways; a braind-dead sample

y=sort(rand(20,2),1,'ascend');      % some dummy y data
figure,hold on                      % new figure, going to add more than one line
for x=0:2:2                         % two sets of lines, specifically...
  arrayfun(@(i)line([x x+1],[y(i,x/2+1) y(i,x/2+1)]),1:length(y)) % add the lines at y,arbitrary x
end
xlim([0 10])                        % set the axis so lines are pleasing width
hAx=gca; hAx.Visible='off';         % don't want visible axis
hF=gcf; hF.Color='w';               % and white background

yields figure looking like--

data=rand(50,50);

A=data(:,1);%your first column

B=data(:,2);%your second column

figure;xlim([1 2]);

for n1=1:length(A)

hold on

refline([0 A(n1)])

end

hold on

xlim([4 5]);

for n2=1:length(B)

hold on

refline([0 B(n2)])

end

xlim([0 6]);

I think this will solve your purpose.
