XYDiagram Class

Represents a diagram that is used to plot all 2D XY series, except for the Gantt and Radar and Polar series views.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v17.2.dll

Declaration

C#

[TypeConverter(typeof(XYDiagramTypeConverter))]
public class XYDiagram :
    XYDiagram2D

VB.NET

<TypeConverter(GetType(XYDiagramTypeConverter))>
Public Class XYDiagram
    Inherits XYDiagram2D

Remarks

The XYDiagram class represents the diagram type used to plot series which are displayed using the X and Y axes. For the complete list of supported series views, refer to XY-Diagram.

In addition to the settings inherited from the base Diagram and XYDiagram2D classes, the XYDiagram class implements specific properties that allow you to control the following characteristics of a diagram.

• settings of the primary X and Y axes (XYDiagram.AxisX, XYDiagram.AxisY);
• settings of the secondary X and Y axes (XYDiagram.SecondaryAxesX, XYDiagram.SecondaryAxesY);
• direction in which a diagram and its axes are rotated (XYDiagram.Rotated).

An object of the XYDiagram type can be accessed via the ChartControl.Diagram property of a chart control that displays series compatible with this diagram type.
