Pivot Chart Title to Display Multiple Selected Items - excel

Question

I have a pivotchart that when the selected filter (work center) is changed, it updates the chart title to display that work center name. However, if I check the box to allow multiple selections, the chart title simply shows "All" instead of showing each of the actual selected items. I haven't found a way to get it to show what I'm looking for. Below is the code that I'm using to update the chart title as well as the code for the filter change event that fires it off
Option Explicit
Private Sub Worksheet_PivotTableUpdate(ByVal Target As PivotTable)
On Error Resume Next
Application.Run "'Prod_Tools.xlam'!gPTWCChange", Target.PivotFields("WorkCenter").CurrentPage
On Error GoTo 0
End Sub
Sub gPTWCChange(ByVal WC As String)
Dim wb1 As Workbook
Dim CPWB1 As Workbook
For Each wb1 In Workbooks
If InStr(1, wb1.Name, "Capacity Planning Rep", vbTextCompare) > 0 Then
Set CPWB1 = Workbooks(wb1.Name)
Exit For
End If
Next wb1
On Error Resume Next
CPWB1.Charts("Workcenter By Week").ChartTitle.Text = "Work Center: " & WC
On Error GoTo 0
End Sub
What I would like is when multiple items are selected, have the chart title look like "Data for: Workcenter_A, Workcenter_B, Workcenter_F"

Here's your adapted sub. Notice that its parameter has changed.
Public Sub gPTWCChange(ByVal pfWC As Excel.PivotField)
Const sSEPARATOR As String = ", "
Dim sChartTitle As String
Dim oPivotItem As Excel.PivotItem
Dim lVisibleCount As Long
'... Your original code ...
Dim wb1 As Workbook
Dim CPWB1 As Workbook
For Each wb1 In Workbooks
If InStr(1, wb1.Name, "Capacity Planning Rep", vbTextCompare) > 0 Then
Set CPWB1 = Workbooks(wb1.Name)
Exit For
End If
Next wb1
'... New code to compute the chart title ...
If pfWC.EnableMultiplePageItems Then
'Build the chart title from the visible items in the PivotField.
lVisibleCount = 0
For Each oPivotItem In pfWC.PivotItems
If oPivotItem.Visible Then
lVisibleCount = lVisibleCount + 1
sChartTitle = sChartTitle & sSEPARATOR & oPivotItem.Caption
End If
Next
'Drop the leading separator.
sChartTitle = Mid$(sChartTitle, Len(sSEPARATOR) + 1)
'Manage plural.
sChartTitle = "Work Center" & IIf(lVisibleCount > 1, "s", "") & ": " & sChartTitle
Else
sChartTitle = "Work Center: " & pfWC.CurrentPage
End If
'... Your original code ...
On Error Resume Next
CPWB1.Charts("Workcenter By Week").ChartTitle.Text = sChartTitle
On Error GoTo 0
End Sub
And call your sub as follows:
Application.Run "'Prod_Tools.xlam'!gPTWCChange", Target.PivotFields("WorkCenter")
The principle is to send your sub a reference to the PivotField object, and from there, check its EnableMultiplePageItems property.
