Önceki konularımızda, grafik için veri kaynağı nasıl ayarlanır gösteren birçok örnek sağladık, ancak bu konuda grafik için ayarlanabilecek veri türleri hakkında daha fazla detay vereceğiz.
Grafik Verisi Ayarlama
Aspose.Cells kullanarak grafikler üzerinde çalışırken ele almanız gereken iki tür veri şunlardır:
- Grafik verisi.
- Kategori verisi.
Grafik Verisi
Grafik verisi, grafiklerimizi oluşturmak için kullandığımız veri kaynağıdır. SeriesCollection nesnesinin add(string, boolean) yöntemini çağırarak, hücre aralığını (grafik verisi içeren) ekleyebiliriz.

worksheet.cells.get("B2").value = 32;
worksheet.cells.get("B3").value = 50;

worksheet.cells.get("C4").value = "Y2";
// Adding a chart to the worksheet
const chartIndex = worksheet.charts.add(AsposeCells.ChartType.Column, 5, 0, 15, 5);
// Accessing the instance of the newly added chart

downloadLink.download = 'output.xls';

});

Kategori Verisi
Kategori verisi, grafik verilerinin etiketlenmesi için kullanılır ve SeriesCollection öğesine categoryData özelliği kullanılarak eklenebilir. Aşağıda, grafik ve kategori verilerinin kullanımını göstermek için tam bir örnek verilmiştir. Yukarıdaki örnek kod çalıştırıldıktan sonra, çalışma sayfasına aşağıdaki gibi bir sütun grafiği eklenecektir.
