Question

我正在Access 2010中构建一些图表并尝试自动化它们。但我无法通过vba应用数据标签。

当我尝试使用ApplyDataLabels时，我收到错误438：

Dim mychart As Object
Dim myseries As Object
Dim ax As Object
Dim pt As Object

Set mychart = frm.ChartSpace.Charts(0)

For Each myseries In mychart.SeriesCollection
    myseries.ApplyDataLabels '438 - Object doesn't support this property or method
Next

我需要做些什么才能使数据标签可用？

提前致谢！

法比奥。

Answer 1

我找到了解决方案：

Dim dl as Object
For Each myseries In mychart.SeriesCollection
        Set dl = myseries.DataLabelsCollection.Add
        dl.NumberFormat = "0.00"
Next

此过程显示/隐藏基于使用 bShow 参数传递的数据的值。图形对象是从表单对象 (oFrmGrafico) 设置的，该对象具有称为 Grafico (oFrmGrafico!Grafico.Object) 的 Graph 类型控件。

util_Log_MsgBoxErr 是一个内部过程。你可以通过MsgBox Err.Number & ": " & Err.Description, vbExclamation

更改它

mbExisteGrafico 是一个全局范围的布尔变量，用于收集图是否存在。

Public Sub MostrarValores(ByVal bMostrar As Boolean)
On Error GoTo MostrarValores_Err

    Dim objGraph As Object  'Chart
    Dim srs As Object       'Series
    Dim pt As Object        'Point
    
    If mbExisteGrafico Then
        Set objGraph = oFrmGrafico!Grafico.Object
        With objGraph
            .ApplyDataLabels
            For Each srs In .SeriesCollection
                For Each pt In srs.Points
                    pt.DataLabel.ShowValue = bMostrar
                Next
            Next
        End With
    End If

MostrarValores_Sal:
On Error Resume Next
    Set pt = Nothing
    Set srs = Nothing
    Set objGraph = Nothing
    Exit Sub
MostrarValores_Err:
    util_Log_MsgBoxErr Err.Number, Err.Description, "Class|Sub: cGraficos", "MostrarValores"
    Resume MostrarValores_Sal
End Sub

为什么Chart ApplyDataLabels在Access 2010中不起作用
