Wie man ein Wasserfalldiagramm erstellt

Mit Aspose.Cells APIs können Sie ein Wasserfalldiagramm mithilfe eines Liniendiagramms erstellen. Die API ermöglicht auch die Anpassung des Diagrammaussehens, um ihm die Form des Wasserfalls zu geben, indem Sie die Series.UpBars und Series.DownBars Eigenschaften setzen.

Der unten bereitgestellte Code-Schnipsel zeigt die Verwendung der Aspose.Cells for .NET API zur Erstellung eines Wasserfalldiagramms von Grund auf.

// 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
Workbook workbook = new Workbook();
// Retrieve the first Worksheet in Workbook
Worksheet worksheet = workbook.Worksheets[0];
// Retrieve the Cells of the first Worksheet
var cells = worksheet.Cells;
// Input some data which chart will use as source
cells["A1"].PutValue("Previous Year");
cells["A2"].PutValue("January");
cells["A3"].PutValue("March");
cells["A4"].PutValue("August");
cells["A5"].PutValue("October");
cells["A6"].PutValue("Current Year");
cells["B1"].PutValue(8.5);
cells["B2"].PutValue(1.5);
cells["B3"].PutValue(7.5);
cells["B4"].PutValue(7.5);
cells["B5"].PutValue(8.5);
cells["B6"].PutValue(3.5);
cells["C1"].PutValue(1.5);

cells["C3"].PutValue(3.5);
cells["C4"].PutValue(9.5);
cells["C5"].PutValue(7.5);
cells["C6"].PutValue(9.5);
// Add a Chart of type Waterfall in same worksheet as of data
int idx = worksheet.Charts.Add(ChartType.Waterfall, 4, 4, 25, 13);
// Retrieve the Chart object
Chart chart = worksheet.Charts[idx];
// Add Series
chart.NSeries.Add("$B$1:$C$6", true);
// Add Category Data
chart.NSeries.CategoryData = "$A$1:$A$6";
// Series has Up Down Bars
chart.NSeries[0].HasUpDownBars = true;
// Set the colors of Up and Down Bars
chart.NSeries[0].UpBars.Area.ForegroundColor = Color.Green;
chart.NSeries[0].DownBars.Area.ForegroundColor = Color.Red;
// Make both Series Lines invisible
chart.NSeries[0].Border.IsVisible = false;
chart.NSeries[1].Border.IsVisible = false;
// Set the Plot Area Formatting Automatic
chart.PlotArea.Area.Formatting = FormattingType.Automatic;
// Delete the Legend
chart.Legend.LegendEntries[0].IsDeleted = true;
chart.Legend.LegendEntries[1].IsDeleted = true;
// Save the workbook
workbook.Save(dataDir + "output_out.xlsx");
