Empty Points Representation
This document describes the XtraCharts capability for treating empty series data points (those that have no values defined for some of their arguments).
Points that have a zero value are treated as empty (or missing) points, meaning that they are not drawn in the diagram and are represented as gaps in the data series.
With the date-time scale type, it is possible to exclude holidays and weekends from an axis scale. To learn more, refer to Data Aggregation.
