Excel VBA – select a range including a hidden column

thanks in advance to anyone willing to help.

I have put together this code to select non continuous cells of a table to create a graph (the number of rows of the table varies)

Sub graphB()
  Dim sht As Worksheet
  Dim LastRow As Long

  Set sht = ThisWorkbook.Worksheets("CF_total")

  LastRow = sht.Range("E2").CurrentRegion.Rows.Count

  ActiveSheet.Shapes.AddChart.Select

  Set myRange = Union(Range(sht.Cells(2, 5), sht.Cells(LastRow, 5)), Range(sht.Cells(2, 12), sht.Cells(LastRow, 12)))

  ActiveChart.SetSourceData Source:=myRange
  ActiveChart.ChartType = xlPie
End Sub

But now I have decided to hide column number 12 of the worksheet(which contains the data that I want to plot) and it does not work anymore. Any ideas on how I could solve this?
Thanks!

ActiveChart.PlotVisibleOnly = False
