Empty Points Representation

This document describes the ASP.NET Charts 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 represented as gaps in the data series.

EmptyPointRepresentation

For Bar charts, there is an option to make series labels visible for empty points via the BarSeriesLabel.ShowForZeroValues property.

ShowForZeroValues = true ShowForZeroValues = false
showForZeroValues_true showForZeroValues_false

With the date-time scale type, it is possible to exclude holidays and weekends from an axis scale. To learn more on this, refer to Data Aggregation.
