Try this (UNTESTED)

试试这个（UNTESTED）

Excel.ChartObject myChart = (Excel.ChartObject)charts.Add(10, 70, 250, 250);

instead of

代替

Excel.ChartObject myChart = (Excel.ChartObject)workbook.Charts[2];

and then once your chart is created, move it to a chart sheet using this code

然后创建图表后，使用此代码将其移动到图表工作表

chart.Location(XlChartLocation.xlLocationAsNewSheet, Type.Missing);
