I have a repeater in my page and i try to use a stepline with the repeater.

in the itemdatabound th bind the data to the chart by filtering. I checked the data after filter and i found all things are ok.

My problem is that the page display the stepline charts but the it repeat the same data in all the charts.  I think that is a problem in the chart when it tries to generate the data.

Have you any idea why the chart does not display the data correctly?

Thank you in advance.
