A series point that has one value per argument.
Namespace: DevExpress.WinUI.Charts
Assembly: DevExpress.WinUI.Charts.v23.2.dll
NuGet Package: DevExpress.WinUI

PointDataBase
#Related API Members
The following members return PointData objects:
#Remarks
The DataPoint
class implements the functionality of an individual data point in a series. Each point has two coordinates.
- X-coordinate (the point’s argument)
- Use the PointDataBase.Argument property to specify the point argument. To explicitly indicate the argument type, set the PointDataBase.ArgumentScaleType property.
- Y-coordinate (the point’s value)
- Use the PointData.Value property to specify the point value. To explicitly indicate the value type, set the PointDataBase.ValueScaleType property.
Note
If a point’s argument or value is missed, this point is considered empty and is not drawn on the chart. Instead, the chart displays a gap in series data.
To add a point to a series, add a PointData
object to the Series.Data collection (a PointDataCollection class instance).
#Example
This example creates a Cartesian chart with 3 Stacked Bar series, populates them with data, and adjusts common settings.
