I have data from last year that I want to compare with data from this year.
The data is broken into components, so I'd like to use a stacked bar graph to
compare the data by month. Is there a way to put two columns of data next to
each other in a stacked bar graph?

X-Axis would have months (Jan - Dec)
Each month would have two columns - one for 2007, one for 2008

Thanks.
