XYDiagramPane Class

Represents an XY-diagram’s additional pane.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v24.1.dll

NuGet Package: DevExpress.Charts


public class XYDiagramPane :


By default, a diagram displays a single default pane, which is represented by the XYDiagramDefaultPane class. If a diagram contains several series, it is possible to display the remaining series on additional panes represented by the XYDiagramPane class.

For more information, refer to Panes.


This example shows how to plot multiple series in separate panes.

  1. Create a ChartControl object.

  2. Create two Series objects. Populate their Points collection with SeriesPoint objects. Add both series to the ChartControl.Series collection. See the Provide Data document for more information on how to create series and populate them with data.

  3. To add a pane in addition to the diagram’s DefaultPane, create a new XYDiagramPane and add it to the Panes collection. Use the XYDiagramSeriesViewBase.Pane property to assign the pane to a series view.

    Use the following API to specify the pane title and position options:

    Member Description
    XYDiagramPaneBase.Title Returns the pane title settings.
    XYDiagram2D.PaneDistance Specifies the distance between a diagram’s panes.
    XYDiagram2D.PaneLayout Returns the diagram’s pane layout configuration.
    XYDiagramPaneBase.LayoutOptions Returns settings that configure the pane’s position in the Grid Layout.
  4. To add a secondary x-axis, add a SecondaryAxisX object to the diagram’s SecondaryAxesX collection. To add a secondary y-axis, add a SecondaryAxisY object to the diagram’s SecondaryAxesY collection. To assign the axes to the view, use the AxisX and AxisY properties.

    Use the following properties to customize the axis options:

    Member Description
    Axis2D.Alignment Specifies the position of an axis relative to another primary axis.
    AxisBase.GridLines Gets the grid lines settings.
