Akıllı İşaretlerin İşlenmesiyle Grafik Oluşturma

Tasarımcı Elektronik Tablonun Oluşturulması

Tasarımcı elektronik tablo, Microsoft Excel uygulaması veya Aspose.Cells API’leri ile oluşturulmuş basit bir Excel dosyasıdır; görsel biçimlendirme, formüller ve akıllı işaretleyiciler içeren, içerikler çalışma zamanında doldurulabilir.

Basitlik açısından, Aspose.Cells for .NET API kullanarak tasarımcı elektronik tablo oluşturacağız ve daha sonra gösterim amaçları için 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");

Tasarımcı Elektronik Tablonun İşlenmesi

Tasarımcı elektronik tablonun işlenmesi için, tasarımcı elektronik tabloda kullanılan Akıllı İşaretleyicilere uygun bir veri kaynağınız olmalıdır. Örneğin, Sales.DataTable’daki Yıl sütununu temsil eden &=Sales.Year şeklinde bir Akıllı İşaretleyici girdisi oluşturduk. Karşılık gelen bir sütun veri kaynağında bulunmuyorsa, Aspose.Cells API’leri o belirli Akıllı İşaretleyici için işlemeyi atlayacak ve sonuç olarak belirli Akıllı İşaretleyici için veriler doldurulmayacaktır.

Bu kullanım durumunu göstermek için, veri kaynağını sıfırdan oluşturacağız ve hazırladığımız tasarımcı elektronik tabloya karşı işleyeceğiz. Bununla birlikte, gerçek zamanlı bir senaryoda, veri zaten mevcutsa, veri kaynağının oluşturulmasını atlayabilirsiniz.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// Create an instance of DataTable and name is according to the Smart Markers
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));
table.Columns.Add("Item2", typeof(int));
table.Columns.Add("Item3", typeof(int));
table.Columns.Add("Item4", typeof(int));
table.Columns.Add("Item5", typeof(int));
table.Columns.Add("Item6", typeof(int));
table.Columns.Add("Item7", typeof(int));
table.Columns.Add("Item8", typeof(int));
table.Columns.Add("Item9", typeof(int));
table.Columns.Add("Item10", typeof(int));
table.Columns.Add("Item11", typeof(int));
table.Columns.Add("Item12", typeof(int));
// Add some rows with data to the DataTable
table.Rows.Add("2000", 2310, 0, 110, 15, 20, 25, 30, 1222, 200, 421, 210, 133);
table.Rows.Add("2005", 1508, 0, 170, 280, 190, 400, 105, 132, 303, 199, 120, 100);
table.Rows.Add("2010", 0, 210, 230, 140, 150, 160, 170, 110, 1999, 1229, 1120, 2300);
table.Rows.Add("2015", 3818, 320, 340, 260, 210, 310, 220, 0, 0, 0, 0, 122);

Grafik Oluşturma

Veri yerine getirildikten sonra, yapmamız gereken tek şey veri kaynağına dayalı bir grafik oluşturmaktır. Örneği basit tutmak için Chart.SetChartDataRange yöntemini kullanacağız, böylece grafikleri daha fazla yapılandırmaya gerek kalmadan kullanabiliriz.
