Handling empty data points at data analysis level

In order to properly handle empty data points the developer must first determine what strategy to use to handle empty data points at data analysis level.

Empty data point support in NDataSeries

Empty data points are represented in data series with the DBNull.Value. Each NDataSeries object has an attached instance of the NEmptyDataPoints class, which is accessible through the EmptyDataPoints property. The most important property of this class is the ValueMode property. It is of type EmptyDataPointsValueMode and accepts the following values:

Skip
Average
CustomValue

Following is a description of these modes:

Chart with empty data points
Skip (Empty Data Points are not displayed)
Average (Empty Data Points are displayed with grey color)
