How to generate daily,weekly frequency reports?

[teamireport]

HI Folks,

I would like to generate a barchart report for daily,weekly  frequncy of my data.

This is what i tried .

1. I'm selecting the data from db with the two parameter ( fromdate, todate) date ranges .for example i'm selecting the data for a date range fromdate: 2009-08-01 ,todate:2009-08-31 . Here i can able to show the bar chart for each day .this is considered as a daily basis.  The same  data  should be show  as a weekly basis.

My question is how to pass a paramter to my query is it daily /weekly frequency.

Note : I know weekly.daily kind of reports can be do in timeseries chart. but i would like to genrate same behaviour in barchart

can anyone help me out on this please ?

 

thanks,
