ZedGraph

 数据源既拼出来的数组，X Y 轴对应数组使用List<String> 从数据源添加最后转换为数组public partial class frmZed_1 : Form    {        DataGridView gridview = null;        DateTime _date_s, _date_e;        GraphPane myPane;        List<string> list_Steel = null;        List<string> List_Mat = null;        public frmZed_1()        {            InitializeComponent();        }        public frmZed_1(DataGridView gridview, DateTime _date_s, DateTime _date_e, List<string> list_Steel,        List<string> List_Mat )            : this()        {            this.gridview = gridview;            this._date_s = _date_s;            this._date_e = _date_e;            this.list_Steel = list_Steel;            this.List_Mat = List_Mat;        }            private void frmZed_1_Load(object sender, EventArgs e)        {            comboBox_Mat.DataSource = List_Mat;            comboBox_Steel.DataSource = list_Steel;            myPane = zed.GraphPane;            myPane.Title.Text = "消耗趋势图";            myPane.Title.FontSpec.Size = 10;            myPane.XAxis.Title.Text = "炉号";            myPane.XAxis.Title.FontSpec.Size = 8;            myPane.YAxis.Title.FontSpec.Size = 8;             zed.IsShowPointValues = true;            myPane.Legend.FontSpec.Size = 5;  //显示信息大小图例            myPane.YAxis.Title.Text="消耗量";            myPane.XAxis.Scale.FontSpec.Angle = 90;//X轴90度            myPane.YAxis.Scale.FontSpec.Size = 5;            myPane.YAxis.Scale.FontSpec.Family = "Times New Roman";            myPane.XAxis.Scale.FontSpec.Size = 5;            myPane.XAxis.Scale.MinorStep = 1;//刻度            CreateChat(gridview);        }        private void CreateChartByColumnName(DataGridView dataGridview)        {            if (dataGridview.DataSource == null) return;            //生成X轴钢种坐标            string Unit = "T";            //if (comboBox_Mat.Text.Contains("线"))            //{            //    Unit = "M";            //}           if (comboBox_Mat.Text.Contains("电"))            {                Unit = "KWH";            }            else            {                Unit = "T";            }              myPane.YAxis.Title.Text=string.Format("消耗量({0})",Unit);              myPane.Title.Text = string.Format("钢种{0}时间从{1}到{2}消耗趋势图", comboBox_Steel.Text, _date_s.ToString("yyyy-MM-dd HH:mm:ss"), _date_e.ToString("yyyy-MM-dd HH:mm:ss"));            DataTable dt = dataGridview.DataSource as DataTable;            DataView dv = new DataView(dt);            dv.RowFilter = string.Format("钢种='{0}'", this.comboBox_Steel.Text);            dv.Sort = "炉号 ASC";            List<string> listlables = new List<string>();             List<double> list_Y = new List<double>();                             //炼钢用铁水,            // sum(cl."废钢铁统料") 废钢铁统料,            // sum(cl."炼钢用铁块") 炼钢用铁块            myPane.CurveList.Clear();                        foreach (DataRowView drv in dv)            {                listlables.Add(drv["炉号"].ToString());                list_Y.Add((drv[comboBox_Mat.Text].Equals(DBNull.Value)) ?
