pie chart problem

hi all,

My query is like this.

select SUM(homerule+cashrule+cleanrule+drillrule) as totalvalues, sum(homerule+cashrule) as leftsidevalue, sum(cleanrule+drillrule) as rightsidevalue, days
from rule_stock_details
group by days
order by days

I want the pie chart to have values of leftsidevalue and rightsidevalue.
please let me know what to use in
VALUE-COLUMN
series-by-field
and also please let me know do i need to use group-by

Thanks,
Malibu
