Bar Graph with varying widths

Hi all,

I was trying to get a stacked bar graph with varying widths. Is it possible? Could someone help me?

Here are the variables I am trying to plot.

These are the value to be plotted in a stacked bar graph

graf =

    0.2075    2.1825
    0.4312    1.9600
    0.0370    2.3600
    0.3107    2.0800
    0.1172    2.2800
    1.3685    1.0200
    0.8685    1.5200
    0.1610    2.2300
    1.0000    0.9300
    0.3107    0.6900

Without varying widths by using

    bar(graf,'stack');

I can get a nice graph like this:

But I also need bars with varying widths, for example, here are my desired widths:

    2     1     3     1     4     3     2     2     1     3

Is there any way I can obtain such a plot? And also a minor question, do you know how I can change colors in a stacked bar graph?

Thanks a lot,

For your 2nd question:

In order to change the bar colors, use findobj to get the patch objects forming the bars and change their color:

   hBars = findobj(gca,'type','patch')

will give a 2-element array of handles, where each color is change individually like so:

    set(hBars(1),'FaceColor','g')
    set(hBars(2),'FaceColor','c')

I'm looking into your first question!

Thanks a lot, For my first question I have found this http://www.mathworks.com/matlabcentral/newsreader/view_thread/77839

However, I can't adapt this to stacked version.
