Tuvalette pasta grafik çizdiğim bir pasta grafik özel görünümüm var.Özel görünümü şişirirken hata oluştu
Pasta grafik değerlerini bir parçanın içindeki etkinlikten gönderiyorum.
Ama
Benim faaliyettir doğru çözümü bulmak mümkün tüm önlemlerin türlü fakat çalıştık pasta chart.I şişirme hatayı alıyorum ...
