RadColumnSparkline Visibility/Alignment not coming if more than 2 year

[Balaji]

Hi , 
 We are using Q1 2011 version of RAD silver light controls.
 
We used this COntrol inside the Timebar control and provide the required Data as

Time Bar - Period start and End date(Jan-1-2009 to Jan-1-2012)
Time Bar - VisiblePeriod start and End date(Jan-1-2009 to Jan-1-2012)


Provided the item source for RadColumnSparkline List of Name and Value for binding for all the dates from Start to end. 
eg. My values will be 0 or 1 , so i have set 1 to First of every month(Jan , Feb etc for all the 3 yrs) and rest of the values as 0. 
I.e [Only one day in month will be having the value as 1 all the others will be zero]

But in the initial load , the column sparkline is not visible, with the same data if i zoom in then the sparkline is visible.
Also if i set 1 to 2nd of every month , then the same is visible?

Is it because of the older version we are using.



Thanks

Hello Balaji,

We created a small demo application using the details you shared and the sparkline loads as expected. The application was tested with Q1 2011 and Q3 2011 libraries and it works as expected in both. I have attached the source code of this test application so that you can test it in your environment.

Kind regards,
