如何使用 VBA 将 ShapeStyle 应用于 Excel 中特定系列的图表？

Question

如何使用 vba 以编程方式将 ShapeStyle 应用于单个图表系列中的一组点？似乎我需要一个“Shapes”对象，它只包含我要格式化的系列中的点？

一些信息在这里：http : //peltiertech.com/WordPress/programming-excel-2007-2010-autoshapes-with-vba/在“设置边框和填充样式”部分下

我有伪代码，但我不知道如何创建只包含我想要的项目的 Shapes 对象

' Applies desired shapestyle to a specific series of a chart

Sub ApplyShapeStyle(ch As Chart, sr As Series, ss As ShapeStyle)

    ' Somehow create a "Shapes" object that 
    ' contains all the points from the series as Shape objects

    Dim shps as Shapes
    'pseudocode
    shps.Add(<all points from series>)
    shps.ShapeStyle = ss

End Sub

Answer 1

就像我在评论中提到的（我可能是错的），没有可用的 shape 属性可以DataLabel让您更改.ShapeStyle. 但是，我设法使用复杂的例程实现了您想要的。

逻辑

1. 在工作表中插入一个临时形状，比如一个矩形
2. 应用.ShapeStyle到这个形状
3. 单独设置的属性DataLabel一样填充，边框颜色，边框样式，阴影等与从形状。
4. 完成后，删除形状。

只是设置一些.Fill属性给了我这个msoShapeStylePreset38
