Hello Andrew,

This behavior that you are currently seeing is expected, as the stacked series in the XamDataChart do not currently support animations. The "transition" related properties do exist on the series, but they exist on the "CategorySeries" base class to the StackedColumnSeries. While it does exist on that class though, it isn't implemented for the StackedColumnSeries currently. If you would like to see animations implemented for the StackedColumnSeries, I would recommend suggesting a new product idea for it at http://ideas.infragistics.com. This product ideas site will place you in direct communication with our product management teams who plan and prioritize upcoming features based on community feedback.

The above is not to say that you can't implement a custom animation on the elements of the XamDataChart, though. If you would like to try doing this, I would recommend taking a look at the following forum thread, where a sample exists on how you can apply a custom animation to the elements of the chart: http://www.infragistics.com/community/forums/t/64711.aspx.

Please let me know if you have any other questions or concerns on this matter.

Sincerely,
Andrew
Associate Developer
