根据范围设置日期数组时出现类型不匹配错误

Question

我的总体问题是我想创建具有动态 x 轴（和 y 轴）比例的动态图表。 x 轴包含我观察的日期。为了设置 x 轴的最小和最大刻度，我尝试创建一个日期数组，并将下限和上限分别设置为我的最小和最大刻度。

运行下面的代码我得到一个

Error 13: Type mismatch error when defining the ArrDate array.

我尝试将数组的内容设置为 as Variant 而不是原来的 as Range。下面是我遇到问题的代码（我试图过滤掉不必要的代码）。

Option Explicit
 Option Base 0

数组不需要使用 Set，你也想给数组 Range.Value 这样就可以了：

Option Explicit
Sub Test()

    Dim arrDate
    Dim Val_Total_Date As Range

    With ThisWorkbook.Sheets(1)
        Set Val_Total_Date = Union(.Range("A:A"), .Range("D:D"))
        arrDate = Val_Total_Date.Value
    End With


End Sub

此外，public 变量是不行的...除了工作表中的变量（在我看来）整数和范围是有风险的，因为任何程序都可能随时更改它们。

这是如果你想给数组值，如果你想制作一个范围数组 arrDate = Array(Val_Total_Date, Range2, Range3...)
