Empty Series Data Points

Empty [series data points] are points that have no argument value defined. This document describes how the DevExpress ASP.NET Chart control treats these empty points.

Empty points are points with undefined Values. This means that the point is not drawn in the diagram, which results in a gap in the data series.

For Bar charts, you can use the BarSeriesLabel.ShowForZeroValues property to display series labels for empty points.

ShowForZeroValues = true ShowForZeroValues = false
showForZeroValues_true showForZeroValues_false

If your chart is of the date-time scale type, you can exclude holidays and weekends from an axis scale. To learn more, refer to the following help topic: Data Aggregation.
