DevExpress 通过WebChartControl 制作饼图的代码

前台代码:

<dxchartsui:WebChartControl ID="wccBrowserStatistics" runat="server" Width="600px"
                    ClientInstanceName="chart" Height="368px" >
                   
                </dxchartsui:WebChartControl>

后台代码:　

　　wccBrowserStatistics.Series.Clear();
            DataTable dt = analytics.GetBrowserCount();
            wccBrowserStatistics.DataSource = dt;
            wccBrowserStatistics.DataBind();
            Series series1 = new Series("浏览器统计", ViewType.Pie);
            wccBrowserStatistics.Series.Add(series1);
            series1.ArgumentScaleType = ScaleType.Qualitative;
            series1.ValueScaleType = ScaleType.Numerical;
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                string name = dt.Rows[i]["IEType"].ToString();
                double browser = Convert.ToDouble(dt.Rows[i]["browser"].ToString());
                series1.Points.Add(new SeriesPoint(IEType, new double[] { browser }));
            }

            SeriesPointFilter filter = new SeriesPointFilter(SeriesPointKey.Value_1,
            DataFilterCondition.LessThanOrEqual, 10);
            //普通饼图
            ((PieSeriesView)series1.View).ExplodedPointsFilters.Add(filter);
            ((PieSeriesView)series1.View).ExplodeMode = PieExplodeMode.UseFilters;
            series1.SeriesPointsSorting = SortingMode.Ascending;
            series1.SeriesPointsSortingKey = SeriesPointKey.Value_1;
            ((PieSeriesView)series1.View).Rotation = 90;
            ((PieSeriesLabel)series1.Label).Position = PieSeriesLabelPosition.Radial;
            ((PieSeriesLabel)series1.Label).Font = new Font("Tahoma", 8);
            ((PiePointOptions)series1.PointOptions).PointView = PointView.ArgumentAndValues;
            //定义chart标题
            ChartTitle CT1 = new ChartTitle();
            CT1.Text = "浏览器统计";
            wccBrowserStatistics.Titles.Add(CT1);
