Assembly: DevExpress.XtraCharts.v20.1.dll

Public Property View As SeriesViewBase

Property Value

Type Description
SeriesViewBase

A SeriesViewBase-derived object that represents the view type of the series.

Remarks

The XtraChart control features multiple series types which allow you to represent data in various forms (Bar, Stacked Bar, Pie, Point and Line series). Use the View property to specify the desired view type for the series.

Each series view type is represented by a specific object which inherits from the base SeriesViewBase class. The View property provides access to the corresponding type specific settings of the series view object (note that for this purpose the property's value should by type cast to a proper series view type).

Note that the view type of a series can also be changed easily at runtime by using the series's SeriesBase.ChangeView method.

Examples

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

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

using DevExpress.XtraCharts;
// ...

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

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

    // Add points to them.
    series1.Points.Add(new SeriesPoint(1, 15));
    series1.Points.Add(new SeriesPoint(2, 18));
    series1.Points.Add(new SeriesPoint(3, 25));
    series1.Points.Add(new SeriesPoint(4, 33));

    series2.Points.Add(new SeriesPoint(1, 10));
    series2.Points.Add(new SeriesPoint(2, 12));
    series2.Points.Add(new SeriesPoint(3, 14));
    series2.Points.Add(new SeriesPoint(4, 17));

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

    // Set the numerical argument scale types for the series,
    // as it is qualitative, by default.
    series1.ArgumentScaleType = ScaleType.Numerical;
    series2.ArgumentScaleType = ScaleType.Numerical;

    // Access the view-type-specific options of the series.
    ((AreaSeriesView)series1.View).Transparency = 80;

    // Access the type-specific options of the diagram.
    ((XYDiagram)areaChart.Diagram).EnableAxisXZooming = true;

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

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