RadCartesianChart - LineSeries bound to collection, blocks app in latest updates

[John]

We have a RadCartesianChart displaying multiple line series bound to observable collections. On the same screen we have multiple graphs displaying a stack AreaSeries too, each series bound to the same collections as the line series in the other chart.

Using either of the 2012.2.x.y releases causes the application to slow down and become unusable when the collections are updated.

Using the 2012.1.326.1050 libraries shows no such effects and overriding 

the OnCollectionChanged for the observable collection to prevent the charts from updating fixes the slowdown (but obviously we don't see the data drawn), so we believe to have isolated the problem to the latest Telerik release.

Has anyone else seen such effects?

Hi John,

We might need a little bit more information on your scenario in order to determine what is going wrong. Will it be possible for you to isolate the problem in a small runnable application that uses some local sample data? This way we will check to see what is slowing down the chart in the Q2 release.

Greetings,
