Power Point VBA-更改每个栏的颜色

Question

我需要根据值将条形颜色更改为红色或绿色。 代码在柱状图上工作正常，但在瀑布图上不工作。 它说：“不支持此操作。”

请帮助使以下代码瀑布图兼容：

Sub UpdateBarColor()

    Dim p As Point
    Dim s As Series
    Dim c As Chart

    Set c = ActiveWindow.Selection.ShapeRange(1).Chart
    Set s = c.SeriesCollection(1)

    For Each p In s.Points
        Debug.Print p.Format.Fill.ForeColor.RGB
    Next

End Sub

Answer 1

这会将瀑布图中的条形更改为灰色（即RGB）。您应该能够对其进行修改以适合您的需求

Set c = ActivePresentation.Slides(1).Shapes(1).Chart.SeriesCollection(1)

   For Each p In c.Points
        p.Format.Fill.ForeColor.RGB = RGB(169, 169, 169)
    Next

从图表中获取xvalues，试试看

Dim arr As Variant
Dim i As Integer
With ActivePresentation.Slides(1).Shapes(1).Chart.SeriesCollection(1)
arr = .XValues
For i = LBound(arr) To UBound(arr)
Debug.Print arr(i)
Next
End With
