ActiveSheet.ChartObjects("图表 1").Activate

    ActiveChart.ChartArea.Copy
    Cells(5, n).Select
    ActiveSheet.Paste
    ActiveSheet.ChartObjects("图表 50").Activate
    ActiveChart.ChartTitle.Select
    Selection.Caption = "=顺河向绘图!$D$1"
    ActiveChart.SeriesCollection(1).Select
    ActiveChart.SeriesCollection(2).Name = "=顺河向绘图!$D$2"
    ActiveChart.SeriesCollection(2).Values = "=顺河向绘图!$D$3:$D$1828"
   
End Sub
就是excel的列，依次从D到AH选择数据
我希望能实现第一幅图为  
Selection.Caption = "=顺河向绘图!$D$1"
    ActiveChart.SeriesCollection(1).Select
    ActiveChart.SeriesCollection(2).Name = "=顺河向绘图!$D$2"
    ActiveChart.SeriesCollection(2).Values = "=顺河向绘图!$D$3:$D$1828"
第二幅图  
Selection.Caption = "=顺河向绘图!$E$1"
    ActiveChart.SeriesCollection(1).Select
    ActiveChart.SeriesCollection(2).Name = "=顺河向绘图!$E$2"
    ActiveChart.SeriesCollection(2).Values = "=顺河向绘图!$E$3:$E$1828"
……
一直到
Selection.Caption = "=顺河向绘图!$AH$1"
    ActiveChart.SeriesCollection(1).Select
    ActiveChart.SeriesCollection(2).Name = "=顺河向绘图!$AH$2"
    ActiveChart.SeriesCollection(2).Values = "=顺河向绘图!$AH$3:$AH$1828"
