Grouping by Date value and then grouping by series value in a chart

Hi,

I have a chart in which I want to display the below results from a SQL Procedure in a grouping according to ReshapingBacklog, TopsoilingBacklog,  SeededBacklog and then group them together according to BudgetYearMonth.

BudgetYearMonth       ReshapingBacklog    TopsoilingBacklog        SeededBacklog
2012-01-01               222.97                    93.64                         60.37
2012-02-01               123.00                    122.00                       322.00
2012-03-01               321.00                    221.00                       111.00

I want is this in a chart like so:

                                           3                 #*                     @  *                            #

                                           2              @#*                     @  *                            #*

                                           1               @#*                     @#*                         @#*

                                                ReshapingBacklog    TopsoilingBacklog        SeededBacklog
