Hi,

I'm running into a problem using a data bound NumericTimeSeries and using NullHandling.InterpolateSimple.  The data in the DataTable being used contains all nulls, and this appears to cause a problem.

Is there a property or setting that I'm missing that prevents this exception from getting thrown?

I realize that I could do some work ahead of time to detect if the chart's values are all null, and not create the chart layer or something like that, but the chart is part of a dynamic data source which allows the changing of the underlying chart data on the fly.  If the user set some values to null after the initial detection, I would have to recreate the entire chart to do the null checking all over again.

Please advise on the best way to proceed.

FYI, I'm using version 8.1.20081.1000 of Infragistics2.Win.UltraWinChart.v8.1.
