Property Value

Type Description
ResolveOverlappingMode

A ResolveOverlappingMode enumeration value.

Remarks

Use the ResolveOverlappingMode property to determine an overlapping resolving mode to be applied to series labels. The set of the available modes varies, depending on the view type of the series.

Examples

The following example demonstrates how to create a ChartControl with a series of the DoughnutSeriesView type, set its general properties, 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_DoughnutChart {
    public partial class Form1 : Form {
        public Form1() {
            InitializeComponent();
        }

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

            // Create a doughnut series.
            Series series1 = new Series("Series 1", ViewType.Doughnut);

            // Populate the series with points.
            series1.Points.Add(new SeriesPoint("Russia", 17.0752));
            series1.Points.Add(new SeriesPoint("Canada", 9.98467));
            series1.Points.Add(new SeriesPoint("USA", 9.63142));
            series1.Points.Add(new SeriesPoint("China", 9.59696));
            series1.Points.Add(new SeriesPoint("Brazil", 8.511965));
            series1.Points.Add(new SeriesPoint("Australia", 7.68685));
            series1.Points.Add(new SeriesPoint("India", 3.28759));
            series1.Points.Add(new SeriesPoint("Others", 81.2));

            // Add the series to the chart.
            DoughnutChart.Series.Add(series1);

            // Specify the text pattern of series labels.
            series1.Label.TextPattern = "{A}: {VP:P0}";

            // Specify how series points are sorted.
            series1.SeriesPointsSorting = SortingMode.Ascending;
            series1.SeriesPointsSortingKey = SeriesPointKey.Argument;

            // Specify the behavior of series labels.
            ((DoughnutSeriesLabel)series1.Label).Position = PieSeriesLabelPosition.TwoColumns;
            ((DoughnutSeriesLabel)series1.Label).ResolveOverlappingMode = ResolveOverlappingMode.Default;
            ((DoughnutSeriesLabel)series1.Label).ResolveOverlappingMinIndent = 5;

            // Adjust the view-type-specific options of the series.
            ((DoughnutSeriesView)series1.View).ExplodedPoints.Add(series1.Points[0]);
            ((DoughnutSeriesView)series1.View).ExplodedDistancePercentage = 30;

            // Access the diagram's options.
            ((SimpleDiagram)DoughnutChart.Diagram).Dimension = 2;

            // Add a title to the chart and hide the legend.
            ChartTitle chartTitle1 = new ChartTitle();
            chartTitle1.Text = "2D Doughnut Chart";
            DoughnutChart.Titles.Add(chartTitle1);
            DoughnutChart.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False;

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

    }
}
