Grafikler, görsel olarak çekicidir ve kullanıcıların verilerde karşılaştırmaları, desenleri ve eğilimleri görüntülemelerini kolaylaştırır. Örneğin, birkaç sütun sayısı analiz etmek yerine, satışların üç aylık dönemlerde düşüp yükselip yükselmediğini veya gerçek satışların projeksiyonlu satışlarla nasıl karşılaştığını bir bakışta görebilirsiniz. Bazen, grafikleri uygulamalarınızda veya web sayfalarınızda sunmanız gerekebilir. Belki Word belgesine, bir PDF dosyasına, bir Power Point sunumuna veya başka bir senaryoda eklemek istersiniz. Basitçe söylemek gerekirse, grafikin bir resim olarak oluşturulmasını istersiniz, böylece kolaylıkla uygulamalarınıza yapıştırabilirsiniz. Bir Resim değerlidir. Çalışma sürecinde, istatistiksel ve grafiksel bilgileri anlaşılır ve kolay bakımı yapılan bir şekilde sunmanız gerekebilir. Office Otomasyonunu deneyebilirsiniz ancak Office otomasyonunun kendi eksileri vardır. Birçok neden ve sorun bulunmaktadır: Örn., Güvenlik, Kararlılık, Ölçeklenebilirlik/Hız, Fiyat, Özellikler vb. Kısacası, Microsoft kendisi, Office otomasyonundan yazılım çözümlerine karşı şiddetle tavsiye etme sebepleri bulunmaktadır: Office tarafından sunulan Sunucu Tarafı Otomasyonu için Düşünceler. Aspose.Cells kullanarak Excel Grafiklerini bir resme dönüştürmek için kullanabileceğiniz başka bir seçenek bulunmaktadır.
