Excel VBA中的简单直方图？

我将数据存储在某个列中（比如A列）。列A的长度不是固定的（取决于代码中前面的步骤）

我需要a列中的值的直方图，并将其放在同一张表中。我需要取A列中的值，自动计算M个箱子，然后给出图

Sub Hist(M As Long, arr() As Single)
Dim i As Long, j As Long
Dim Length As Single
ReDim breaks(M) As Single
ReDim freq(M) As Single

For i = 1 To M
    freq(i) = 0
Next i

Length = (arr(UBound(arr)) - arr(1)) / M

For i = 1 To M
    breaks(i) = arr(1) + Length * i
Next i

For i = 1 To UBound(arr)
    If (arr(i) <= breaks(1)) Then freq(1) = freq(1) + 1
    If (arr(i) >= breaks(M - 1)) Then freq(M) = freq(M) + 1
    For j = 2 To M - 1
        If (arr(i) > breaks(j - 1) And arr(i) <= breaks(j)) Then freq(j) = freq(j) + 1
    Next j
Next i

For i = 1 To M
    Cells(i, 1) = breaks(i)
    Cells(i, 2) = freq(i)
Next i
End Sub

我在网上寻找一个“简单”的代码，但所有的代码都非常花哨，有很多我不需要的细节，甚至我都无法使用它。（我是VBA初学者。）

我发现下面的代码似乎可以完成这项工作，但我甚至无法调用该函数。此外，它只做计算，不做绘图

Sub Hist(M As Long, arr() As Single)
Dim i As Long, j As Long
Dim Length As Single
ReDim breaks(M) As Single
ReDim freq(M) As Single

For i = 1 To M
    freq(i) = 0
Next i

Length = (arr(UBound(arr)) - arr(1)) / M

For i = 1 To M
    breaks(i) = arr(1) + Length * i
Next i

For i = 1 To UBound(arr)
    If (arr(i) <= breaks(1)) Then freq(1) = freq(1) + 1
    If (arr(i) >= breaks(M - 1)) Then freq(M) = freq(M) + 1
    For j = 2 To M - 1
        If (arr(i) > breaks(j - 1) And arr(i) <= breaks(j)) Then freq(j) = freq(j) + 1
    Next j
Next i

For i = 1 To M
    Cells(i, 1) = breaks(i)
    Cells(i, 2) = freq(i)
Next i
End Sub

不是100%确定该方法的有效性，但是

• 删除作为您呼叫sub的Paren<代码>历史M，arr

• M

  声明为

  double

  ，但函数接收为

  long

  ；这不起作用，所以在调用例程中将其声明为

  long

• 您需要将

  arr（）作为变量接收

• Range->Array

  生成一个二维数组，因此元素是

  arr（1，1）。。arr（n，1）

有点晚了，但我还是想分享我的解决方案。我创建了一个直方图函数，可以在excel电子表格中使用。注意：您必须按

CTRL+SHIFT+ENTER

将公式输入工作簿。输入是直方图的值范围和箱数M。输出范围必须有M行和两列。一列用于存储单元值，一列用于存储单元频率

Option Explicit
Option Base 1

Public Function Histogram(arr As Range, M As Long) As Variant
On Error GoTo ErrHandler
    Dim val() As Variant
    val = arr.Value
    Dim i As Long, j As Integer
    Dim Length As Single
    ReDim breaks(M) As Single
    ReDim freq(M) As Integer

    Dim min As Single
    min = WorksheetFunction.min(val)
    Dim max As Single
    max = WorksheetFunction.max(val)

    Length = (max - min) / M

    For i = 1 To M
        breaks(i) = min + Length * i
        freq(i) = 0
    Next i

    For i = 1 To UBound(val)
        If IsNumeric(val(i, 1)) And Not IsEmpty(val(i, 1)) Then
            If val(i, 1) > breaks(M) Then
                freq(M) = freq(M) + 1
            Else
                j = Int((val(i, 1) - min) / Length) + 1
                freq(j) = freq(j) + 1
            End If
        End If
    Next i

    Dim res() As Variant
    ReDim res(M, 2)
    For i = 1 To M
        res(i, 1) = breaks(i)
        res(i, 2) = freq(i)
    Next i

    Histogram = res
ErrHandler:
    'Debug.Print Err.Description
End Function
