如何在visual studio c#中对序列图表进行分组和命名

using System.Windows.Forms.DataVisualization.Charting;

// 创建序列图表
Chart chart = new Chart();

// 设置图表的宽度和高度
chart.Width = 500;
chart.Height = 300;

// 创建序列
Series series1 = new Series("Series1");
Series series2 = new Series("Series2");

// 将序列添加到图表中
chart.Series.Add(series1);
chart.Series.Add(series2);

// 设置序列的类型（例如柱状图、折线图等）
series1.ChartType = SeriesChartType.Column;
series2.ChartType = SeriesChartType.Line;

// 设置序列的数据
series1.Points.AddXY("A", 10);
series1.Points.AddXY("B", 20);
series1.Points.AddXY("C", 30);

series2.Points.AddXY("A", 5);
series2.Points.AddXY("B", 15);
series2.Points.AddXY("C", 25);

// 将图表添加到窗体中
this.Controls.Add(chart);

// 创建图表区域
ChartArea chartArea = new ChartArea();

// 设置X轴的分组方式
chartArea.AxisX.IsLabelAutoFit = false;
chartArea.AxisX.LabelStyle.IsStaggered = true;

// 将图表区域添加到图表中
chart.ChartAreas.Add(chartArea);

series1.Name = "Group 1";
series2.Name = "Group 2";
