Error when changing data binding on a chart

[thubble]

Using build 3499. There's a crash that happens when the following steps are performed:

1. Set a bar chart's ItemsSource to something, and set its AllSeries.StackedStyle to "No".

2. Set the chart's ItemsSource to something different, which has more points than the previous ItemsSource, and set the AllSeries.StackedStyle to "Normal".

 This seems to crash with the following stack trace:

Index was outside the bounds of the array.

I've attached an app that reproduces this issue. If you open it, then click on "Stacked", then "Unstacked", then "Stacked" again, it should produce that error.

We have fixed this issue and we are in the process of testing the fix, It should be available in our next hotfix build 3511 or later.

Thank you for providing an application that exhibits the issue.
