Time Series - Date gets repeated

[jawwadfarooq1]

I am using Jasper Reports to create TIme Series chart.

Problem: If the days are less than 7, days get repeated on Time Series chart. Lets suppose my data consists of 20, 21, 22 April, then on chart i get 20, 20, 21, 21, 22, 22 April alongwith x-axis. And the time period attribute is set to 'Day'.

Please tell how this dupplication can be removed.

 

Thanks in advance...

Regards,
