XYDiagramPaneBase.Weight Property

OBSOLETE

This property is obsolete now. Use the Diagram.PaneLayout.RowDefinitions or Diagram.PaneLayout.ColumnDefinitions property to specify the pane's Weight. Refer to the http://docs.devexpress.com/WindowsForms/5881 page for more information about the new layout system.

Gets or sets the relative size of the XYDiagramPaneBase if the pane’s XYDiagramPaneBase.SizeMode property is set to PaneSizeMode.UseWeight.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v18.2.dll

Property Value

Type Description
Double

An integer value which specifies the pane’s size, in relation to other panes.

Remarks

If a pane’s size is specified by the Weight property, this size is proportionally recalculated when the chart is resized.

Note

The chart calculates the pane’s height according to the axis and labels sizes. So, the series view area’s height can differ for each pane, whether the Weight property is specified or not. This happens when X-axis labels are not shown for all panes and take significant space on a diagram.

To provide an equal size of each series view area in panes, change the pane’s size (relative or absolute) for those panes whose axis labels require too much space on a diagram.

For more information, refer to Panes.

Example

This example demonstrates how panes can be accessed and customized at runtime.

Assuming that there are two series of the line view type in the chart, in the following code, we create an additional pane, and assign the second series to it. In addition, a secondary axis is created and assigned to that series, and it is also visible in the additional pane.

using System;
using System.Drawing;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...

private void Form1_Load(object sender, EventArgs e) {
    // Create a new chart.
    ChartControl chartControl1 = new ChartControl();

    // Create two series.
    Series series1 = new Series("Series 1", ViewType.Bar);
    Series series2 = new Series("Series 2", ViewType.Line);

    // Add points to them, with their arguments different.
    series1.Points.Add(new SeriesPoint("A", 10));
    series1.Points.Add(new SeriesPoint("B", 12));
    series1.Points.Add(new SeriesPoint("C", 17));
    series1.Points.Add(new SeriesPoint("D", 14));
    series2.Points.Add(new SeriesPoint("I", 2500));
    series2.Points.Add(new SeriesPoint("II", 3800));
    series2.Points.Add(new SeriesPoint("III", 1500));
    series2.Points.Add(new SeriesPoint("IV", 1300));

    // Add both series to the chart.
    chartControl1.Series.AddRange(new Series[] { series1, series2 });

    // Hide the legend (optional).
    chartControl1.Legend.Visible = false;

    // Cast the chart's diagram to the XYDiagram type, 
    // to access its axes and panes.
    XYDiagram diagram = (XYDiagram)chartControl1.Diagram;

    // Add secondary axes to the diagram, and adjust their options.
    diagram.SecondaryAxesX.Add(new SecondaryAxisX("My Axis X"));
    diagram.SecondaryAxesY.Add(new SecondaryAxisY("My Axis Y"));
    diagram.SecondaryAxesX[0].Alignment = AxisAlignment.Near;
    diagram.SecondaryAxesY[0].Alignment = AxisAlignment.Near;

    // Add a new additional pane to the diagram.
    diagram.Panes.Add(new XYDiagramPane("My Pane"));

    // Assign both the additional pane and, if required,
    // the secondary axes to the second series. 
    LineSeriesView myView = (LineSeriesView)series2.View;
    myView.AxisX = diagram.SecondaryAxesX[0];
    myView.AxisY = diagram.SecondaryAxesY[0];
    // Note that the created pane has the zero index in the collection,
    // because the existing Default pane is a separate entity.
    myView.Pane = diagram.Panes[0];

    // Customize the layout of the diagram's panes.
    diagram.PaneDistance = 10;
    diagram.PaneLayoutDirection = PaneLayoutDirection.Horizontal;
    diagram.DefaultPane.SizeMode = PaneSizeMode.UseWeight;
    diagram.DefaultPane.Weight = 1.2;

    // Add the chart to the form.
    chartControl1.Dock = DockStyle.Fill;
    this.Controls.Add(chartControl1);
}
