chartControl绑定数据源

Posted 2020-08-01 有容乃大：好读书不求甚解

        private void BindChartControl(DataTable dataTable,ChartControl chartControl,int[] columnNO,ViewType viewType)
        {
            chartControl.Series.Clear();
            int num = columnNO.Length;
            List<Series> series=new List<Series>();

            for (int i = 0; i < num; i++) 
            {
                Series singleSeries = new Series(dataTable.Columns[columnNO[i]].Caption,viewType);
                series.Add(singleSeries);
            }

            foreach(DataRow dr in dataTable.Rows)
            {
                if (dr[0] != null) 
                {
                    for (int i = 0; i < columnNO.Length; i++) 
                    {
                        SeriesPoint point = new SeriesPoint(dr[0].ToString());

                        point.Values = new double[] {Convert.ToDouble(dr[dataTable.Columns[columnNO[i]].Caption]) };

                        series[i].Points.Add(point);
                    }
                }
            }

            chartControl.Series.AddRange(series.ToArray());
        }
