Ein Tortendiagramm in VSTO und Aspose.Cells erstellen

Dieser Artikel vergleicht, wie man ein Kreisdiagramm mit Office Automation und VSTO im Vergleich zur Verwendung von Aspose.Cells for .NET erstellt. Die Schritte zum Erstellen eines Kreisdiagramms lauten:

1. Erstellen eines Arbeitsblatts und Arbeitsblattes.
2. Hinzufügen von Beispieldaten.
3. Verweisen auf productsChart.
4. Hinzufügen eines Kreisdiagramms, Definieren des Datenbereichs und des Diagrammtitels.
5. Speichern der Arbeitsmappe. Die Codebeispiele in diesem Artikel zeigen, wie man ein Kreisdiagramm mit VSTO hinzufügt, entweder mit C#, im Vergleich dazu, eines mit Aspose.Cells erstellt, wiederum mit C#.

VSTO

 private void PieChart()

{

//Instantiate the Application object.

Excel.Application ExcelApp = Application;

//Add a Workbook.

Excel.Workbook objBook = ExcelApp.Workbooks.Add(System.Reflection.Missing.Value);

// Access a Vsto Worksheet

Microsoft.Office.Interop.Excel.Worksheet nativeWorksheet = Globals.ThisAddIn.Application.ActiveWorkbook.ActiveSheet;

Microsoft.Office.Tools.Excel.Worksheet sheet = Globals.Factory.GetVstoObject(nativeWorksheet);

//Add sample data for pie chart

//Add headings in A1 and B1

sheet.Cells[1, 1] = "Products";

sheet.Cells[1, 2] = "Users";

//Add data from A2 till B4

sheet.Cells[2, 1] = "Aspose.Cells";

sheet.Cells[2, 2] = 10000;

sheet.Cells[3, 1] = "Aspose.Slides";

sheet.Cells[3, 2] = 8000;

sheet.Cells[4, 1] = "Aspose.Words";

sheet.Cells[4, 2] = 12000;

//Chart reference

Microsoft.Office.Tools.Excel.Chart productsChart;

//Add a Pie Chart

productsChart = sheet.Controls.AddChart(0, 105, 330, 200, "ProductUsers");

productsChart.ChartType = Microsoft.Office.Interop.Excel.XlChartType.xlPie;

//Set chart title

productsChart.HasTitle = true;

productsChart.ChartTitle.Text = "Users";

//Gets the cells that define the data to be charted.

Microsoft.Office.Interop.Excel.Range chartRange = sheet.get_Range("A2", "B4");

productsChart.SetSourceData(chartRange, missing);

//Access the Active workbook from Vsto sheet

Microsoft.Office.Interop.Excel.Workbook workbook = sheet.Application.ActiveWorkbook;

//Save the copy of workbook as OutputVsto.xlsx

workbook.SaveCopyAs("OutputVsto.xlsx");

}

Aspose.Cells

 private static void PieChart()

{

	//Create Aspose.Cells Workbook

	Workbook workbook = new Workbook();

	//Access Aspose.Cells Worksheet

	Worksheet sheet = workbook.Worksheets[0];

	//Add sample data for pie chart

	//Add headings in A1 and B1

	sheet.Cells["A1"].PutValue("Products");

	sheet.Cells["B1"].PutValue("Users");

	//Add data from A2 till B4

	sheet.Cells["A2"].PutValue("Aspose.Cells");

	sheet.Cells["B2"].PutValue(10000);

	sheet.Cells["A3"].PutValue("Aspose.Slides");

	sheet.Cells["B3"].PutValue(8000);

	sheet.Cells["A4"].PutValue("Aspose.Words");

	sheet.Cells["B4"].PutValue(12000);

	//Chart reference

	Chart productsChart;

	//Add a Pie Chart

	int chartIdx = sheet.Charts.Add(ChartType.Pie, 7, 0, 20, 6);

	productsChart = sheet.Charts[chartIdx];

	//Gets the cells that define the data to be charted

	int seriesIdx = productsChart.NSeries.Add("=Sheet1!$B$2:$B$4", true);

	Series nSeries = productsChart.NSeries[seriesIdx];

	nSeries.XValues = "=Sheet1!$A$2:$A$4";

	//Set chart title

	productsChart.Title.Text = "Users";

	//Autofit first column

	sheet.AutoFitColumn(0);

	//Save the copy of workbook as OutputAspose.xlsx

	workbook.Save("OutputAspose.xlsx");
