Declaration

public class BubbleSeriesView :
    PointSeriesViewBase,
    IXYWSeriesView,
    IXYSeriesView,
    ISeriesView,
    ISupportAssignTransparencyView,
    ISupportTransparency
Public Class BubbleSeriesView
    Inherits PointSeriesViewBase
    Implements IXYWSeriesView,
               IXYSeriesView,
               ISeriesView,

Remarks

The BubbleSeriesView class provides the functionality of a series view of the Bubble type within a chart control.

In addition to the common view settings inherited from the base PointSeriesViewBase class, the BubbleSeriesView class declares specific point type settings which allow you to define the settings of point markers (BubbleSeriesView.BubbleMarkerOptions), the maximum and minimum allowed size of bubbles (BubbleSeriesView.MaxSize and BubbleSeriesView.MinSize) and the transparency of bubbles (BubbleSeriesView.Transparency).

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

For more information on the Bubble series view, please see the Bubble Chart topic.

Examples

The following example demonstrates how to create a ChartControl with two series of the BubbleSeriesView 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 System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...

namespace Series_BubbleChart {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
        }

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

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

            // Add points to them.
            series1.Points.Add(new SeriesPoint(1, 11, 2));
            series1.Points.Add(new SeriesPoint(2, 10, 1));
            series1.Points.Add(new SeriesPoint(3, 14, 3));
            series1.Points.Add(new SeriesPoint(4, 17, 2));

            series2.Points.Add(new SeriesPoint(1, 15, 3));
            series2.Points.Add(new SeriesPoint(2, 18, 4));
            series2.Points.Add(new SeriesPoint(3, 25, 2));
            series2.Points.Add(new SeriesPoint(4, 33, 1));

            // Add both series to the chart.
            bubbleChart.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.
            ((BubbleSeriesView)series1.View).AutoSize = false;
            ((BubbleSeriesView)series1.View).MaxSize = 1;
            ((BubbleSeriesView)series1.View).MinSize = 0.3;
            ((BubbleSeriesView)series1.View).BubbleMarkerOptions.Kind = MarkerKind.Circle;

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

            // Hide the legend (if necessary).
            bubbleChart.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False;

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