Examples

The following example demonstrates how to specify the appearance of series labels in the Pie chart using its text pattern.

To accomplish this at runtime, it is necessary to handle the Form.Load event and then transform series labels of the Series object to the corresponding labels of the PieSeriesLabel object.

And finally, specify the pattern for series labels using the SeriesLabelBase.TextPattern property.

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

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

        private void Form1_Load(object sender, EventArgs e) {
            // Create an empty chart.
            ChartControl pieChart = new ChartControl();

            // Create a pie series.
            Series series1 = new Series("A Pie Series", ViewType.Pie);

            // 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.
            pieChart.Series.Add(series1);

            // Adjust the text pattern of the series label.
            PieSeriesLabel label = (PieSeriesLabel)series1.Label;
            label.TextPattern = "{A}: {VP:P0}";

            // Detect overlapping of series labels.
            label.ResolveOverlappingMode = ResolveOverlappingMode.Default;

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