We are trying to serialize to disk large ChartControl files, by *clearing* all data points first and then saving the data
using the following code:

**********************
foreach (NSeries Series in Chart.Series)
{
Series.ClearDataPoints();
}
ChartControl.Document.Calculate();
ChartControl.Refresh();

ChartControl.Serializer.SaveControlStateToFile(FileName, PersistencyFormat.Binary, new NDataSerializationFilter());
**********************

However when we do this the file size changes depending on number of data points. These files can be quite large 10MB-30MB and loading them again can take 30sec to 2min even though there should be no datapoints in the file. We want to keep all the series in the ChartControl but remove all its points before saving to reduce the file size. Any thoughts on how we can do this?
