Achartengine Çizgi Grafik

Question

Çizgi Grafik oluşturmak için Achartengine kullanıyorum. Şu anki ayım gösteriliyor ancak ikinci satır, geçen ay gösterilmiyor. İşte lass ve logcat: Eğer logcat'ten görebildiğiniz gibi, tarihlerim doğru ve bir önceki ayın sayısı. Öyleyse neden gösterilmiyor, benim dışımda.

teşekkürler bana yol @Dan çözüm. Tüm doğru değerleri doğru diziye yerleştirildiğinden emin olmak için bütün noktaları kaydettim ve bir şekilde yArray.add(c.getInt(c.getColumnIndex(StatusData.KEY_CHARTING_TEMPERATURE))); bir şekilde silindi. Yani şimdi çalışıyor! Yuppi!
