JuanC, The chart has a single pane with each series being added to the chart in the code (on the DataContextChanged event of the page) Each series has its own independent ItemsSource, all using the same Property Thanks, Mike

I receive an IndexOutOfRangeException when removing a certain SeriesAttributes from the first pane of my chart (magic number seems to be between 4 and 6 before the exception is thrown). My chart has multiple panes, and I add several series with the following code: chart.Series.Add(series);chart.Panes[0].Series.Add(series); and remove the same series with this code: chart.Panes[0].Series.Remove(series);chart.Series.Remove(series); Is this not the correct way to add and remove series from a single pane? I've tried wrapping my Add/Remove calls in DispatcherOperationCallback methods and invoke them with the Dispatcher of the chart object, but no luck there.Here's the exception details: System.IndexOutOfRangeException was unhandled Message="Index was outside the bounds of the array."
