TeeChart绘制多个饼图

最近一段时间在学习使用TeeChart

private void DrawPie()
    {
        Chart chart1 = WebChart1.Chart;
        WebChart1.PictureFormat = Steema.TeeChart.Export.PictureFormats.Bitmap;
        //设置保存数据形式，默认File，一般选session。Chart.Aspect(外观属性)
        WebChart1.TempChart = Steema.TeeChart.Web.TempChartStyle.Session;
        WebChart1.GetChartFile = "GetChart.aspx";

        chart1.Header.Text = "饼图";
        //是否显示图例
        chart1.Legend.Visible = false;

        Steema.TeeChart.Styles.Pie pie1 = new Steema.TeeChart.Styles.Pie();
        Steema.TeeChart.Styles.Pie pie2 = new Steema.TeeChart.Styles.Pie();
        Steema.TeeChart.Styles.Pie pie3 = new Steema.TeeChart.Styles.Pie();

        chart1.Series.Add(pie1);  
        chart1.Series.Add(pie2);
        chart1.Series.Add(pie3);
       

        //WebChart1.Chart.ChartRect = new Rectangle(10, 10, 10, 10);
        chart1.Series[0].Add(1, 120);
        chart1.Series[0].Add(2, 320);
        //pie1.BeforeDrawValues += new PaintChartEventHandler(pie1_BeforeDrawValues);
        

        chart1.Series[1].Add(1, 120);
        chart1.Series[1].Add(2, 320);
        chart1.Series[1].Add(3, 420);
        chart1.Series[1].Add(4, 220);
        //pie2.BeforeDrawValues += new PaintChartEventHandler(pie2_BeforeDrawValues);  

        chart1.Series[2].Add(1, 120);
        chart1.Series[2].Add(2, 320);
        chart1.Series[2].Add(3, 420);
        chart1.Series[2].Add(4, 220);

        for (int i = 0; i < 3; i++)
        {
            //显示标注
            chart1.Series[i].Marks.Visible = true;
        }
    }

   或者固定显示位置：

   void pie2_BeforeDrawValues(object sender, Steema.TeeChart.Drawing.Graphics3D g)
    {
        WebChart1.Chart.ChartRect = new Rectangle(WebChart1.Chart.Width / 2, 10, WebChart1.Chart.Width / 2 - 20, WebChart1.Chart.Height / 2 - 20);
    }

    void pie1_BeforeDrawValues(object sender, Steema.TeeChart.Drawing.Graphics3D g)
    {
        WebChart1.Chart.ChartRect = new Rectangle(10, 10, WebChart1.Chart.Width / 2 - 20, WebChart1.Chart.Height / 2 - 20);
    }

如果大家有其它关于TeeChart的知识及帮助，希望能共同交流、学习~
