如何用代码使饼形图上数字变为百分数，而图例不受影响，数据和文字都来自sqlite数据库

Question

 string dbPath = @"D:\历年高考分数.db";
            string sq = @"Data Source=" + dbPath;
            m = new SQLiteConnection(sq);
            m.Open();
            SQLiteDataAdapter mAdapter = new SQLiteDataAdapter("select Volume1,Volume2 from 饼形图2", m);
            DataSet ds = new DataSet();
            mAdapter.Fill(ds);
            DataTable dt = ds.Tables[0];
            //设置图表的数据
            chart3.DataSource = dt;
            //chart3.Series.Clear();
            chart3.Series[0].ChartType = SeriesChartType.Pie;//设置形状
            chart3.Series[0].XValueMember = "Volume1";//图例数据成员列
            chart3.Series[0].YValueMembers = "Volume2";//饼形图上数据成员列
            chart3.Series[0].IsValueShownAsLabel = true;//显示标签
            chart3.DataBind();
            chart3.Width = 260;
            chart3.Height = 260;
            m.Close();

下面的几种尝试都不对
一：chart1.ChartAreas[0].AxisX.LabelStyle.Format = "#LEGENDTEXT";//显示当前图例的标签文本
chart1.ChartAreas[0].AxisY.LabelStyle.Format = "#VAL%";//显示当前图例的所占的百分比
二：chart1.Series[0].Label = "#VALY%";
三：chart1.ChartAreas[0].AxisX.LabelStyle.Format = "#VALX";
chart1.ChartAreas[0].AxisY.LabelStyle.Format = "#VALY%";

Answer 1

已解决，chart1.Series[0].XValueType = ChartValueType.String;x轴显示类型的问题
