Visual Basic (Usage)	Copy Code

public DataPointAttributes EmptyPointStyle {get; set;}

Return Value

A DataPointAttributes object.

EmptyPointStyle determines the drawing style of points marked as empty (e.g. border color, use of marker images, background color or images, etc.).

Note that certain properties are only applicable for specific chart types. For example, the BackImage property does not apply to line charts, but does apply to an area chart.

To display an image that indicates an empty point use the MarkerImage and MarkerStyle properties, and not the BackImage property.

The AxisLabel property determines the axis label for empty points. Note that for stacked chart types the axis label is determined by the AxisLabel property of the first plotted series that has this property set.

Data points can be manually marked as an empty by setting the DataPoint.Empty property to true. Alternatively the DataManipulator.InsertEmptyPoints method can be used to check for missing data and insert empty points if a data point is missing.

NOTE: For line-type charts the line color for lines that connect to an empty point are determined by the EmptyPointStyle.Color property setting.
