I have a report where I am calculating the TOP5 values based by date. 03/09/2010 04/09/2010 Count------Type Count Type 200 ----- Ms Outlook 200 MsOutlook 300-------desktop 300 desktop 400-------laptop 400 laptop 500-------other 600 notebook 700 microsoft 700 microsoft On the stacked column chart for the date 03/09/2010 it is displaying the top 5, but it is also displaying "0". I guess it is displaying "0" because there is no notebook in 03/09/2010. And in legend it is diplaying notebook twice. Any help.
