Önceki konularımızda, grafiğiniz için bir veri kaynağını nasıl ayarlayabileceğinizi göstermek için birçok örnek vermiştik ancak bu konuda, bir grafik için ayarlanabilecek veri türleri hakkında daha fazla ayrıntı sağlayacağız.
Grafik Verilerini Ayarlama
Aspose.Cells’i kullanarak grafikler üzerinde çalışırken ele alınması gereken iki tür veri vardır:
Grafik Verileri
Grafik verileri, grafiklerimizi oluşturmak için veri kaynağı olarak kullandığımız verilerdir. Çağırarak bir hücre aralığı (grafik verileri içeren) ekleyebiliriz.Seri Koleksiyonu nesneninEklemek yöntem.
