The graphics in that document are not 'fields' so a macro to update all the fields would be as follows.
I have included a debug line so you can review (in the VBA Immediate Window) all the fields that get updated by this macro.
Code:
Sub UpdateFields()
Dim aFld As Field
For Each aFld In ActiveDocument.Fields
Debug.Print aFld.Type & ": " & aFld.Code
aFld.Update
Next aFld
End Sub
