Default Inserting Rows based on cell differences and interpolating in between

Hello -

I have a complicated issue. I have a file with 5 columns (A, B, C, D, E).
A is fixed string value.
B is a number increasing irregularly.
C, D, E, are given values.

What I need to do is have column B regular (i.e. every 1). So I have to insert columns between B (i.e. B2-B1) will determine how many rows between B1 & B2 and then B3-B2 will determine how many rows between B2 & B3 and so on.
After this inserting the rows, I have to linear interpolate columns C, D & E in the newly create empty columns. In all cases I want to keep the original values and interpolate between them.

The other issue is that column B has decimal/fraction, but I think I can round this to the nearest integer to make it easier for interpolation.

Default Inserting Rows based on cell differences and interpolating in between

I tried this one but I think I have a problem with the insert loop!

Option Explicit
Sub Test01()
Application.ScreenUpdating = False
Dim numRows As Long
Dim r As Long
Dim Rng As Range
Dim lastrw As Long
Dim Ar As Range
Dim StepValue1
Dim StepValue2
Dim StepValue3
Dim Ar1 As Range
Dim AR2 As Range

Dim i As Integer
lastrw = Cells(Rows.Count, "A").End(xlUp).Row

i = 1
For i = i + 0 To lastrw Step 1

Set Rng = Range(Cells(i, "A"), Cells(lastrw, "A"))
numRows = Cells(i + 1, 2).Value - Cells(i + 0, 2).Value

For r = Rng.Rows.Count To 1 Step -1
Rng.Rows(r + i).Resize(numRows - 1).EntireRow.Insert
Next r
Next i


Set Rng = Columns(1).SpecialCells(xlBlanks)
For Each Ar In Rng.Areas
Set Ar1 = Ar.Offset(-1, 0).Resize(Ar.Rows.Count + 1)
Set AR2 = Ar1.Resize(Ar1.Rows.Count + 1)

StepValue1 = (AR2(AR2.Count).Offset(0, 2) - _
Ar1(1).Offset(0, 2)) / Ar1.Count

StepValue2 = (AR2(AR2.Count).Offset(0, 3) - _
Ar1(1).Offset(0, 3)) / Ar1.Count

StepValue3 = (AR2(AR2.Count).Offset(0, 4) - _
Ar1(1).Offset(0, 4)) / Ar1.Count

Ar1.Offset(0, 2).DataSeries Rowcol:=xlColumns, _
Type:=xlLinear, Date:=xlDay, _
Step:=StepValue1, Trend:=False

Ar1.Offset(0, 3).DataSeries Rowcol:=xlColumns, _
Type:=xlLinear, Date:=xlDay, _
Step:=StepValue2, Trend:=False

Ar1.Offset(0, 4).DataSeries Rowcol:=xlColumns, _
Type:=xlLinear, Date:=xlDay, _
Step:=StepValue3, Trend:=False

Next

End Sub

Default Inserting Rows based on cell differences and interpolating in between

Hello -

I have a complicated issue. I have a file with 5 columns (A, B, C, D,
E). A is fixed string value.
B is a number increasing irregularly.
C, D, E, are given values.

What I need to do is have column B regular (i.e. every 1). So I have
to insert columns between B (i.e. B2-B1) will determine how many
rows between B1 & B2 and then B3-B2 will determine how many rows
between B2 & B3 and so on. After this inserting the rows, I have to
linear interpolate columns C, D & E in the newly create empty
columns. In all cases I want to keep the original values and
interpolate between them.

The other issue is that column B has decimal/fraction, but I think I
can round this to the nearest integer to make it easier for
interpolation.


My approach would be to separate adding more rows from the business
logic. I use something like this...


Sub InsertBlankRows(Optional Position As String)
' Inserts a specified number of rows at the location specified.
' If the Position arg is not used then the default is ActiveCell.Row.
Dim vRows As Variant, lPos As Long
Const sMsg As String = "Enter the number of rows to insert."

'Evaluate user input
On Error Resume Next
vRows = InputBox(Prompt:=sMsg, Default:=1): If vRows = "" Then Exit
Sub '//user cancels
If Not Err = 0 Or Not IsNumeric(vRows) Or Not vRows = 1 Then Exit
Sub

'Get the position to insert
lPos = IIf(Position = "Below", lPos + 1, ActiveCell.Row)

'Insert the rows
ActiveSheet.Rows(lPos).Resize(vRows).Insert Shift:=xlDown
End Sub 'InsertBlankRows

...and use it like this...

Sub AddMoreRows()
Dim vAns, sPos$
vAns = MsgBox("Insert rows ABOVE here?", vbYesNo, "Insert Rows")
sPos = IIf(vAns = vbYes, "Above", "Below")
InsertBlankRows sPos
End Sub

Corretion...

Sub InsertBlankRows(Optional Position As String)
' Inserts a specified number of rows at the location specified.
' If the Position arg is not used then the default is ActiveCell.Row.
Dim vRows As Variant, lPos As Long
Const sMsg As String = "Enter the number of rows to insert."

'Evaluate user input
On Error Resume Next
vRows = InputBox(Prompt:=sMsg, Default:=1): If vRows = "" Then Exit
Sub '//user cancels
If Not Err = 0 Or Not IsNumeric(vRows) Or Not vRows = 1 Then Exit
Sub

'Get the position to insert
lPos = ActiveCell.Row: If Position = "Below" Then lPos = lPos + 1

'Insert the rows
ActiveSheet.Rows(lPos).Resize(vRows).Insert Shift:=xlDown
End Sub
