[DevExpress]饼状图突出（Explode）设置

关键代码：

        /// <summary>
        /// 饼状图突出设置
        /// </summary>
        /// <param name="chart">ChartControl</param>
        /// <param name="pieSeries">Series【仅仅适用于PieSeriesView】</param>
        /// <param name="explodeMode">突出模式【枚举】</param>
        /// <param name="explodedValue">突出间距</param>
        /// <param name="dragPie">是否可以拖动突出饼状</param>
        public static void SetPieExplode(this ChartControl chart, Series pieSeries, PieExplodeMode explodeMode, int explodedValue, bool dragPie)
        {
            if (pieSeries.View is PieSeriesView)
            {
                //bool _hitTesting = chart.RuntimeHitTesting;
                if (!chart.RuntimeHitTesting)
                    chart.RuntimeHitTesting = true;

                PieSeriesView _pieView = pieSeries.View as PieSeriesView;
                _pieView.ExplodeMode = explodeMode;
                _pieView.ExplodedDistancePercentage = explodedValue;
                _pieView.RuntimeExploding = dragPie;

                // chart.RuntimeHitTesting = _hitTesting;
            }
        }

代码使用：

        private void BuilderDevChart()
        {
            Series _pieSeries = new Series("Series 1", ViewType.Pie);
            _pieSeries.ValueDataMembers[0] = "Value";
            _pieSeries.ArgumentDataMember = "Name";
            _pieSeries.DataSource = CreateChartData();
            chartControl1.Series.Add(_pieSeries);
            //----------------------------------------
            _pieSeries.LegendPointOptions.PointView = PointView.ArgumentAndValues;
            _pieSeries.SetPiePercentage(NumericFormat.Percent, PointView.ArgumentAndValues);
            chartControl1.SetAxisXTitle("test", Color.Red);
            _pieSeries.SetLablePosition(PieSeriesLabelPosition.TwoColumns);
            chartControl1.SetPieExplode(_pieSeries, PieExplodeMode.MinValue, 5, true);

        }
