Akıllı İşaretleyicileri İşleyerek Grafik Oluşturun

Tasarımcı Elektronik Tablosunun Oluşturulması

Bir tasarımcı elektronik tablosu, Microsoft Excel uygulaması veya Aspose.Cells API’leri ile oluşturulmuş, içeriğin çalışma zamanında doldurulabileceği görsel biçimlendirme, formüller ve akıllı işaretleyiciler içeren basit bir Excel dosyasıdır.

Basitlik adına, Aspose.Cells for .NET API’i kullanarak tasarımcı elektronik tablosunu oluşturacağız ve daha sonra gösteri amacıyla dinamik olarak oluşturulmuş bir veri kaynağına karşı işleyeceğiz.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
// Create an instance of Workbook
var book = new Workbook();
// Access the first, default Worksheet by passing its index
var dataSheet = book.Worksheets[0];
// Name the Worksheet for later reference
dataSheet.Name = "ChartData";
// Access the CellsCollection of first Worksheet
var cells = dataSheet.Cells;
// Insert static data (headers)
cells["B1"].PutValue("Item 1");
cells["C1"].PutValue("Item 2");
cells["D1"].PutValue("Item 3");
cells["E1"].PutValue("Item 4");
cells["F1"].PutValue("Item 5");
cells["G1"].PutValue("Item 6");
cells["H1"].PutValue("Item 7");
cells["I1"].PutValue("Item 8");
cells["J1"].PutValue("Item 9");
cells["K1"].PutValue("Item 10");
cells["L1"].PutValue("Item 11");
cells["M1"].PutValue("Item 12");
// Place Smart Markers
cells["A2"].PutValue("&=Sales.Year");
cells["B2"].PutValue("&=Sales.Item1");
cells["C2"].PutValue("&=Sales.Item2");
cells["D2"].PutValue("&=Sales.Item3");
cells["E2"].PutValue("&=Sales.Item4");
cells["F2"].PutValue("&=Sales.Item5");
cells["G2"].PutValue("&=Sales.Item6");
cells["H2"].PutValue("&=Sales.Item7");
cells["I2"].PutValue("&=Sales.Item8");
cells["J2"].PutValue("&=Sales.Item9");
cells["K2"].PutValue("&=Sales.Item10");
cells["L2"].PutValue("&=Sales.Item11");
cells["M2"].PutValue("&=Sales.Item12");

İşleme Tasarımcısı Elektronik Tablosu

Tasarımcı elektronik tablosunu işlemek için, tasarımcı elektronik tablosunda kullanılan Akıllı İşaretleyicilere karşılık gelen bir veri kaynağına sahip olunmalıdır. Örneğin, &=Sales.Year olarak DataTable Sales’de Year sütununu temsil eden bir Smart Marker girdisi oluşturduk. Veri kaynağında karşılık gelen bir sütun yoksa, Aspose.Cells API’leri söz konusu Akıllı İşaretleyici için işlemeyi atlayacak ve sonuç olarak belirli Akıllı İşaretleyici için veriler doldurulmayacaktır.

Bu kullanım örneğini göstermek için veri kaynağını sıfırdan oluşturacağız ve onu önceki adımda oluşturulan tasarımcı elektronik tablosuna göre işleyeceğiz. Bununla birlikte, gerçek zamanlı bir senaryoda, veriler daha sonraki işlemler için zaten mevcut olabilir; bu nedenle, veriler zaten mevcutsa veri kaynağının oluşturulmasını atlayabilirsiniz.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET

var table = new DataTable("Sales");
/*
* Add columns to the newly created DataTable while specifying the column type
* It is important that the DataTable should have at least one column for each
* Smart Marker entry from the designer spreadsheet
*/
table.Columns.Add("Year", typeof(string));
table.Columns.Add("Item1", typeof(int));
