我正在编写一个excel应用程序,它从表格中获取信息(它也被编程并且每个表格的长度和位置可以改变)并在按下按钮时为另一个表格中的每个表格生成一个图形,称为估算表.

我设法为第一个图形(对应于第一个表)完成了这项任务,但是当我尝试对第二个图形使用相同的方法时......它不起作用。这是用于绘制第一个图形的方法:

    Public Sub generateGraphicsC(RowResistiveC As Integer)

       Dim FirstRow As Integer, FirstColumn As Integer, LastRow As Integer, LastColumn As Integer,         GraphLocation As Integer
       Dim XelementsC As Integer, Yelements As Integer

       Dim myChtObj As ChartObject
       Dim rngChtData As Range
       Dim rngChtXVal As Range
       Dim i As Integer


       Dim WSD As Worksheet
       Set WSD = Worksheets(2)     'Data source

       Dim CSD As Worksheet
       Set CSD = Worksheets(3)     'ChartOutput

       'Dim chrt As ChartObject
       'Dim cw As Long
       'Dim rh As Long

       ' get the current charts so proper overwriting can happen Dim chtObjs As ChartObjects
       Set chtObjs = CSD.ChartObjects
       WSD.AutoFilterMode = False       ' Turn off autofilter mode
       'Dim finalRow As Long            ' Find the last row with data
       'finalRow = WSD.Cells(Application.Rows.Count, 1).End(xlUp).Row


       FirstRow = RowResistiveC
       FirstColumn = 5

       XelementsC = countXelementsC(FirstRow - 1, FirstColumn)                  'Count the x         Elements (amperes)
       Yelements = countYelements(FirstRow)                                      'Count the y Elements (Combinations)

       LastRow = FirstRow + Yelements - 1                                      'The last row and column I will read
       LastColumn = FirstColumn + XelementsC - 1

       '---------------------DRAW THE GRAPHIC----------------------------------------------'

       ' Delete any previous existing chart
        'Dim chtObj As ChartObject

       ' define the x axis values
       WSD.Activate
       Set rngChtXVal = WSD.Range(Cells(FirstRow - 1, FirstColumn), Cells(FirstRow - 1, LastColumn))

       ' add the chart
          Charts.Add

          With ActiveChart
          ' make a XY chart
             .ChartType = xlXYScatterLines
             ' remove extra series
             Do Until .SeriesCollection.Count = 0
                .SeriesCollection(1).Delete
             Loop

             .Location Where:=xlLocationAsObject, Name:="Estimation Sheets"
          End With

          '-----------------------------------------------------------------------------
          With ActiveChart

          'To get the serie name that I´m going to add to the graph
          Dim serieName As String
          Dim varItemName As Variant
          WSD.Activate
          varItemName = WSD.Range(Cells(i, 1), Cells(i, 4))
          serieName = CStr(varItemName(1, 1) + " " + varItemName(1, 2) + " " + varItemName(1, 3) + " " + varItemName(1, 4))

          ' add series from selected range, column by column

             CSD.ChartObjects.Select


            With ActiveChart
                With .SeriesCollection.NewSeries
                .Values = rngChtData
                .XValues = rngChtXVal
                .Name = serieName

        Next i

         'We let as last view the page with all the info
         CSD.Select


    End Sub

我正在从另一个调用这个 Sub。下一步将为其他类型的表格和图形调用类似的方法(完全相同但其他起点来获取数据和一些不同的格式属性):

    Public Sub printGraphics()

       Modul4.ClearGraphs

       Modul4.generateGraphicsC (RowResistiveC)

       Modul4.generateGraphicsT (RowResistiveT)

    End Sub

等等。CountXelements 和 Yelements 计算来自 Tables Sheet 和 RowResistiveC 的元素数量,例如,保持表格的位置。

GenerateGraphicsC 工作,但 generateGraphicsT (完全相同)在行中粉碎:

With .SeriesCollection.NewSeries

Whit 错误 91(我有一个德语版的 excel 在工作,但它类似于变量对象或未给出块对象)。

正如我怀疑错误来自:

CSD.ChartObjects.Select

这在我的第一个图形的解决方案中有效,因为我选择了工作表上的单个图形,但是当我添加更多时它不会。

我刚刚将该行更改为:

CSD.ChartObjects(1).Activate

等等。它完美地工作。我还必须进行一些调整以避免所有图表都绘制在前一个图表上,但效果很好。
