My Data Format Look like This : DDate,Year,Value
in LinqDataSource_Selecting base of RadioButton i get a year , 2years or 3 Years Data
and then if selection is 2 or 3 years data then i set DataGroupColumn = "Year"
if for fist time i select 3 years then move to 2 years or this year every thing is fine
if for fist time i select 2 years then move to this year is Ok, But if go to 3 years chart will show just 2 group in chart and legend !!
if for fist time i select this year , and then i go to 2 or 3 years still will show me 1 group in chart and legend
i can see i chart data items every thing works as the it should be but just it is not showing new groups !!
is there anyway i can force chart to Re-group it's self
