AxisBase.Interlaced Property

Gets or sets whether interlacing is applied to the axis.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v19.2.dll

Declaration

[XtraChartsLocalizableCategory(XtraChartsCategory.Appearance)]
public bool Interlaced { get; set; }
<XtraChartsLocalizableCategory(XtraChartsCategory.Appearance)>
Public Property Interlaced As Boolean

Property Value

Type Description
Boolean

true to apply interlacing; otherwise, false.

Remarks

To specify the interlaced color and fill style use the AxisBase.InterlacedColor and Axis2D.InterlacedFillStyle (or Axis3D.InterlacedFillStyle) properties, respectively. In the image below interlacing is applied to the X Axis:

The following images demonstrate how the Interlaced property works.

Interlaced = false Interlaced = true
Axis_Interlaced_False Axis_Interlaced_True

Examples

The following example demonstrates how to create a ChartControl with two series of the OverlappedGanttSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.

Then, add the following code to the Form.Load event handler.

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

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

    // Create two Gantt series.
    Series series1 = new Series("Planned", ViewType.Gantt);
    Series series2 = new Series("Completed", ViewType.Gantt);

    // Set the date-time values scale type for both series,
    // as it is qualitative, by default.
    series1.ValueScaleType = ScaleType.DateTime;
    series2.ValueScaleType = ScaleType.DateTime;

    // Add points to them.
    series1.Points.Add(new SeriesPoint("Market analysis", new DateTime[] { 
    new DateTime(2006, 8, 16), new DateTime(2006, 8, 23) }));
    series1.Points.Add(new SeriesPoint("Feature planning", new DateTime[] { 
    new DateTime(2006, 8, 23), new DateTime(2006, 8, 26) }));
    series1.Points.Add(new SeriesPoint("Implementation", new DateTime[] { 
    new DateTime(2006, 8, 26), new DateTime(2006, 9, 26) }));
    series1.Points.Add(new SeriesPoint("Testing & bug fixing", new DateTime[] { 
    new DateTime(2006, 9, 26), new DateTime(2006, 10, 10) }));

    series2.Points.Add(new SeriesPoint("Market analysis", new DateTime[] { 
    new DateTime(2006, 8, 16), new DateTime(2006, 8, 23) }));
    series2.Points.Add(new SeriesPoint("Feature planning", new DateTime[] { 
    new DateTime(2006, 8, 23), new DateTime(2006, 8, 26) }));
    series2.Points.Add(new SeriesPoint("Implementation", new DateTime[] { 
    new DateTime(2006, 8, 26), new DateTime(2006, 9, 10) }));

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

    // Access the view-type-specific options of the series.
    ((GanttSeriesView)series1.View).BarWidth = 0.6;
    ((GanttSeriesView)series2.View).BarWidth = 0.3;

    // Access the type-specific options of the diagram.
    GanttDiagram myDiagram = (GanttDiagram)overlappedGanttChart.Diagram;

    myDiagram.AxisY.Interlaced = true;
    myDiagram.AxisY.GridSpacing = 10;
    myDiagram.AxisY.Label.Angle = -30;
    myDiagram.AxisY.DateTimeOptions.Format = DateTimeFormat.MonthAndDay;

    // Add task links for the first Gantt series.
    ((GanttSeriesView)series1.View).LinkOptions.ArrowHeight = 7;
    ((GanttSeriesView)series1.View).LinkOptions.ArrowWidth = 11;
    for (int i = 1; i < series1.Points.Count; i++) {
        series1.Points[i].Relations.Add(series1.Points[i - 1]);
    }

    // Add a progress line.
    ConstantLine progress =
    new ConstantLine("Current progress", new DateTime(2006, 9, 10));
    progress.ShowInLegend = false;
    progress.Title.Alignment = ConstantLineTitleAlignment.Far;
    myDiagram.AxisY.ConstantLines.Add(progress);

    // Adjust the legend.
    overlappedGanttChart.Legend.AlignmentHorizontal = 
        LegendAlignmentHorizontal.Right;

    // Add a title to the chart (if necessary).
    overlappedGanttChart.Titles.Add(new ChartTitle());
    overlappedGanttChart.Titles[0].Text = "R&amp;D Schedule";

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