             Chart3.BackColor = Color.Moccasin;

             // add and format the title
             Chart3.Titles.Add("标题");
             Chart3.Titles[].Font = new Font("Utopia", , FontStyle.Bold);

             Chart3.Series.Add(new Series("Pie")
             {

             });
             Chart3.Series[].Label = "#VALX \n\n #PERCENT{P}";//显示百分比和说明
             Chart3.Series[].LegendText = "#VALX";
             double[] yValues = { , , , , };
             string[] xValues = { "优秀", "不及格", "良好", "及格" };

             //每个部分开花
             foreach (DataPoint point in Chart3.Series[].Points)
