Setting X-Axis Scale in Chart

I've written a program to set the range of values visible in an excel chart based on user input. The program works when there are dates in the x-axis. It throws an error when I try to modify the code for an x-axis that has a number rather than a date.

This is the code that works (x-axis of chart is an excel formatted date):

Sub xaxis_reset()
  Dim start_date As Variant
  Dim end_date As Variant
  Dim w As Long, ws As Long
  Dim z As Long, obj As Long

  start_date = InputBox("Start Date")
  end_date = InputBox("End Date")
  ws = ActiveWorkbook.Worksheets.Count - 2

  For w = 1 To ws
    obj = Worksheets(w).ChartObjects.Count
    For z = 1 To obj
      Worksheets(w).ChartObjects(z).Activate
      With ActiveChart
        .Axes(xlCategory).MinimumScale = DateValue(start_date)
        .Axes(xlCategory).MaximumScale = DateValue(end_date)
      End With
    Next z
  Next w
End Sub

This is my attempt to modify the code to work for a chart that has numbers (year-months) in the x-axis.

Sub xaxis_reset()
  Dim start_yr_mnth_cd As Variant
  Dim end_yr_mnth_cd As Variant
  Dim w As Long, ws As Long
  Dim z As Long, obj As Long

  start_yr_mnth_cd = InputBox("Start YR_MNTH_CD")
  end_yr_mnth_cd = InputBox("End YR_MNTH_CD")
  ws = ActiveWorkbook.Worksheets.Count - 2

  For w = 1 To ws
    obj = Worksheets(w).ChartObjects.Count
    For z = 1 To obj
      Worksheets(w).ChartObjects(z).Activate
      With ActiveChart
        .Axes(xlCategory).MinimumScale = start_yr_mnth_cd
        .Axes(xlCategory).MaximumScale = end_yr_mnth_cd
      End With
    Next z
  Next w
End Sub

The line .Axes(xlCategory).MinimumScale = start_yr_mnth_cd throws an error.

I've tried changing start_yr_mnth_cd and end_yr_mnth_cd from Variant to Long. I've also tried changing the x-axis values in the chart to the general format instead of number. I've made similar changes to the source data in the excel file, even though I don't think that should make a difference. I'm not sure where else to look at this point.

Just in case it helps, this is what the x-axis source data looks like:

201701
201702
201703
201704
201705
201706
201707
201708
201709
201710
201711
201712
201801
201802
201803
201804
201805
201806
201807

Try using the code below (Copy Everything). The private function I added basically takes a YYYYMM format and converts it to a date format that excel understand.

Sub xaxis_reset()
  Dim start_yr_mnth_cd As Variant
  Dim end_yr_mnth_cd As Variant
  Dim w As Long, ws As Long
  Dim z As Long, obj As Long

  start_yr_mnth_cd = InputBox("Start YR_MNTH_CD")
  end_yr_mnth_cd = InputBox("End YR_MNTH_CD")

  start_yr_mnth_cd=ConvertYYYYMM_To_Date(start_yr_mnth_cd)
  end_yr_mnth_cd=ConvertYYYYMM_To_Date(end_yr_mnth_cd)
  ws = ActiveWorkbook.Worksheets.Count - 2

  For w = 1 To ws
    obj = Worksheets(w).ChartObjects.Count
    For z = 1 To obj
      Worksheets(w).ChartObjects(z).Activate
      With ActiveChart
        .Axes(xlCategory).MinimumScale = start_yr_mnth_cd
        .Axes(xlCategory).MaximumScale = end_yr_mnth_cd
      End With
    Next z
  Next w
End Sub

Private Function ConvertYYYYMM_To_Date(vDate As Variant) As Date

ConvertYYYYMM_To_Date = DateValue(Right(vDate, 2) & "-" & Left(vDate, 4))

End Function

Hope this helps
