Sheet SaveAs PDF containg a chart (the chart does not show the legend...)

[drom]

Hi and thanks in advance!

I am saving a sheet X in a new Workbook using a looping, calculate... as:

• a new workbook containing only 1 Sheet
• a new PDF file (just a replica of the saved excel file, sheet)

This works Fine.
I use:

Dim WKBvba As Workbook:           Set WKBvba = ThisWorkbook 'Name of the workbook you are copying from

                                    Workbooks.Add 1 'adds new workbook containing 1 sheet
Dim WKBnew As Workbook:             Set WKBnew = ActiveWorkbook
  WKBvba.Sheets(wsPtReport).Copy Before:=WKBnew.Sheets(1)
  WKBnew.Sheets(2).Delete
      ActiveSheet.Calculate 'In case...
    Cells.Copy
    Cells.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=False
'I do a few more things, like delete non desired Shapes, named ranges etc...
    
    ActiveSheet.ExportAsFixedFormat _
        Type:=xlTypePDF, _
        Filename:=wFxFNpdf, _
        Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, _
        IgnorePrintAreas:=False, _
        OpenAfterPublish:=False
    If WKBnew.Sheets.Count <> WKBvba.Sheets.Count Then     'My model contains many sheets, the Worksheet, only 1, this is why I use this as Stop any crash (a way to stop saving my model with a new name)..
        WKBnew.SaveAs Filename:=wFxFNxls, FileFormat:=xlWorkbookDefault
        WKBnew.Close False
    End If

wFxFNpdf = is the Fullname I use for my new created PDF file
wFxFNxls = is the Fullname I use for my new created Excel file

My Problem:
The sheet contains a Chart and this chart comes with No Category labels, No Legend (everything else comes OK in my new created PDF file (check this photo) :

While in my new Excel file I get:

So I do not know Whats wrong ??
Why the :

• Category labels comes Black
• Legend comes Black 'this Legend has No Formula

When I open the new created excel file, (comes perfect, with everything OK, comes as it should)
But the PDF shows everything OK, except the chart legend and category labels WHY ??
