Thanks robitcus for your prompt reply. I appreciate. I will use your example, since you already have the example working. Your comment says. 
my @data = (
    [ 'Windows', 'Linux', 'Solaris' ],
    # Swap the next two lines to switch versions of the graph 
    [ 150, 250, 350 ], 
    [ 100, 200, 300 ], 
);

This show exactly what I am trying to resolve. By switching 
 [ 150, 250, 350 ], 
 [ 100, 200, 300 ],

to 
 [ 100, 200, 300 ],
 [ 150, 250, 350 ],

Does indeed swap the stacked bars, however the values do not follow the bars. So, stacked bar 1 has values
100 for bottom bar 150 for top bar. If I swap them, the vales 100,150 remain and do not follow the bars it should be referencing.
I may not be understand perl and/or Graphs as I am very new to this. Thanks for any pointers you can provide.
