Hi,

I am hoping the community can assist me here. I found a starting point of VBA code online to assist but unable to make it work for my needs. I am looking to adjust multiple charts in one sheet to minimum values for changing data and maximum values of changing data for both primary and secondary axis.

Here is the code I am using. This only works for primary axis on all charts, it sets minimum to 0, which is not what I need and max to max, which is good.

VBA
-----------
Sub AdjustVerticalAxis()
'PURPOSE: Adjust Y-Axis according to Min/Max of Chart Data
'SOURCE: www.TheSpreadsheetGuru.com
Dim cht As ChartObject
Dim srs As Series
Dim FirstTime As Boolean
Dim MaxNumber As Double
Dim MinNumber As Double
Dim MaxChartNumber As Double
Dim MinChartNumber As Double
Dim Padding As Double
'Input Padding on Top of Min/Max Numbers (Percentage)
Padding = 0 'Number between 0-1
'Optimize Code
Application.ScreenUpdating = False

'Loop Through Each Chart On ActiveSheet
For Each cht In ActiveSheet.ChartObjects

'First Time Looking at This Chart?
FirstTime = True

'Determine Chart's Overall Max/Min From Connected Data Source
For Each srs In cht.Chart.SeriesCollection
'Determine Maximum value in Series
MaxNumber = Application.WorksheetFunction.Max(srs.Values)

'Store value if currently the overall Maximum Value
If FirstTime = True Then
MaxChartNumber = MaxNumber
ElseIf MaxNumber > MaxChartNumber Then
MaxChartNumber = MaxNumber
End If

'Determine Minimum value in Series (exclude zeroes)
MinNumber = Application.WorksheetFunction.Min(srs.Values)

'Store value if currently the overall Minimum Value
If FirstTime = True Then
MinChartNumber = MinNumber
ElseIf MinNumber > MinChartNumber Then
MinChartNumber = MinNumber
End If

'First Time Looking at This Chart?
FirstTime = False
Next srs

'Rescale Y-Axis
cht.Chart.Axes(xlValue).MinimumScale = MinChartNumber * (1 - Padding)
cht.Chart.Axes(xlValue).MaximumScale = MaxChartNumber * (1 + Padding)

Next cht
'Optimize Code
Application.ScreenUpdating = True
End Sub
