从datagridview到chart C#，将第一行加倍

// 获取datagridview的数据
List<List<int>> data = new List<List<int>>();
for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
    List<int> row = new List<int>();
    for (int j = 0; j < dataGridView1.Columns.Count; j++)
    {
        int value = Convert.ToInt32(dataGridView1.Rows[i].Cells[j].Value);
        row.Add(value);
    }
    data.Add(row);
}

// 将第一行数据加倍
List<int> firstRow = data[0];
for (int i = 0; i < firstRow.Count; i++)
{
    firstRow[i] *= 2;
}

// 创建chart控件并绑定数据
Chart chart = new Chart();
chart.DataSource = firstRow;
chart.Series.Add("Series1");
chart.Series["Series1"].ChartType = SeriesChartType.Column;
chart.Series["Series1"].XValueMember = "Index";
chart.Series["Series1"].YValueMembers = "Value";
chart.DataBind();

// 设置chart的显示样式
chart.ChartAreas.Add("ChartArea1");
chart.ChartAreas["ChartArea1"].AxisX.Title = "Index";
chart.ChartAreas["ChartArea1"].AxisY.Title = "Value";

// 显示chart控件
this.Controls.Add(chart);
