Erstellung eines Wasserfalldiagramms

Erstellung eines Wasserfalldiagramms

Aspose.Cells APIs ermöglichen die Erstellung eines Wasserfalldiagramms mithilfe eines Liniendiagramms. Die API ermöglicht es auch, das Diagrammaussehen anzupassen, um ihm die Form des Wasserfalls zu geben, indem die wichtigsten Eigenschaften zur Formung des Diagramms eingestellt werden, eine; Series.UpBars & Series.DownBars Eigenschaften.

Der unten stehende Codeausschnitt zeigt die Verwendung der Aspose.Cells for Java-API, um ein Wasserfalldiagramm von Grund auf zu erstellen.

Java-Code zum Erstellen eines Wasserfalldiagramms

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getDataDir(CreateWaterfallChart.class);
// Create an instance of Workbook
Workbook workbook = new Workbook();
// Retrieve the first Worksheet in Workbook
Worksheet worksheet = workbook.getWorksheets().get(0);
// Retrieve the Cells of the first Worksheet
Cells cells = worksheet.getCells();
// Input some data which chart will use as source
cells.get("A1").putValue("Previous Year");
cells.get("A2").putValue("January");
cells.get("A3").putValue("March");
cells.get("A4").putValue("August");
cells.get("A5").putValue("October");
cells.get("A6").putValue("Current Year");
cells.get("B1").putValue(8.5);
cells.get("B2").putValue(1.5);
cells.get("B3").putValue(7.5);
cells.get("B4").putValue(7.5);
cells.get("B5").putValue(8.5);
cells.get("B6").putValue(3.5);
cells.get("C1").putValue(1.5);

cells.get("C3").putValue(3.5);
cells.get("C4").putValue(9.5);
cells.get("C5").putValue(7.5);
cells.get("C6").putValue(9.5);
// Add a Chart of type Waterfall in same worksheet as of data
int idx = worksheet.getCharts().add(ChartType.WATERFALL, 4, 4, 25, 13);
// Reterieve the Chart object
Chart chart = worksheet.getCharts().get(idx);
// Add Series
chart.getNSeries().add("$B$1:$C$6", true);
// Add Category Data
chart.getNSeries().setCategoryData("$A$1:$A$6");
// Series has Up Down Bars
chart.getNSeries().get(0).setHasUpDownBars(true);
// Set the colors of Up and Down Bars
chart.getNSeries().get(0).getUpBars().getArea().setForegroundColor(Color.getGreen());
chart.getNSeries().get(0).getDownBars().getArea().setForegroundColor(Color.getRed());
// Make both Series Lines invisible
chart.getNSeries().get(0).getBorder().setVisible(false);
chart.getNSeries().get(1).getBorder().setVisible(false);
// Set the Plot Area Formatting Automatic
chart.getPlotArea().getArea().setFormatting(FormattingType.AUTOMATIC);
// Delete the Legend
chart.getLegend().getLegendEntries().get(0).setDeleted(true);
chart.getLegend().getLegendEntries().get(1).setDeleted(true);
// Save the workbook
workbook.save(dataDir + "output.xlsx");
