OverlappedGanttSeriesView Class

Represents a series view of the Overlapped Gantt type.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v19.2.dll

Declaration

public class OverlappedGanttSeriesView :
    GanttSeriesView
Public Class OverlappedGanttSeriesView
    Inherits GanttSeriesView

Remarks

The OverlappedGanttSeriesView class provides the functionality of a series view for the overlapped Gantt type within a chart control.

The OverlappedGanttSeriesView class inherits properties and methods from the base GanttSeriesView class which defines the common settings of Gantt series views.

Note that a particular view type can be defined for a series via its SeriesBase.View property.

For more information on series views of the overlapped Gantt type please see the Overlapped Gantt Chart topic.

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);
 }
