How can I create a plot with column headings along the X-axis?

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])

Thank you very much, Star Strider. Could I ask for more??

I already have the column headers in another 1x4 matrix. CellA1 contains heading of column 1 . CellA2 contains heading of column 2 and so on. Is there a way to label with these headings instead of 'column 1', 'column 2' etc... along the x-axis?

Thank you very much for helping out.

As always, my pleasure.

If your column headers are in a cell array (here I call it ‘YourCellArray’), the line that writes the x-axis labels changes to:

set(gca, 'XTick',x,  'XTickLabel',YourCellArray, 'XTickLabelRotation',90)

That should work.

Thank you very much. It is working perfectly now.
