MATLAB: How to create a plot with column headings along the X-axis

label axisplot

Hi I need to plot a matrix such that every column heading is listed along the x-axis and every cell in that column is plotted along the Y-axis? I have attached a picture of the same. I am a newbie to MATLAB. Could someone please help? Thanks in advance Deepa

Try this:
M = randi(9, 3);                                        % Create Matrix
x = 1:size(M,2);                                        % Column numbers
labelstr = sprintf('Column %d\n', x);                   % Create Labels
labelcel = regexp(labelstr, '\n', 'split');             % Split & Create Cell Array
figure(1)
plot(x, M', '.b', 'MarkerSize',20)
set(gca, 'XTickLabel',[])
set(gca, 'XTick',x,  'XTickLabel',labelcel(1:end-1), 'XTickLabelRotation',90)
axis([0  4    0  10])
