Encapsulates the object that represents the floor of a 3-D chart.
Example:
//Instantiate the License class
License license = new License();
//Pass only the name of the license file embedded in the assembly
license.setLicense("Aspose.Cells.lic");
//Instantiate the workbook object
Workbook workbook = new Workbook();
//Get cells collection
Cells cells = workbook.getWorksheets().get(0).getCells();
//Put values in cells
cells.get("A1").putValue(1);
cells.get("A2").putValue(2);
cells.get("A3").putValue(3);
//get charts colletion
ChartCollection charts = workbook.getWorksheets().get(0).getCharts();
//add a new chart
int index = charts.add(ChartType.COLUMN_3_D_STACKED, 5, 0, 15, 5);
//get the newly added chart
Chart chart = charts.get(index);
//set charts nseries
chart.getNSeries().add("A1:A3", true);
//Show data labels
chart.getNSeries().get(0).getDataLabels().setShowValue(true);
//Get chart's floor
Floor floor = chart.getFloor();
//set floor's border as red
floor.getBorder().setColor(com.aspose.cells.Color.getRed());
//set fill format
floor.getFillFormat().setPresetColorGradient(GradientPresetType.CALM_WATER, GradientStyleType.DIAGONAL_DOWN, 2);
//save the file
workbook.save("dest.xls");
public boolean getInvertIfNegative() / public void setInvertIfNegative(boolean value)
If the property is true and the value of chart point is a negative number,
the foreground color and background color will be exchanged.
Example:
//Instantiating a Workbook object
Workbook workbook = new Workbook();
//Adding a new worksheet to the Workbook object
int sheetIndex = workbook.getWorksheets().add();
//Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.getWorksheets().get(sheetIndex);
//Adding a sample value to "A1" cell
worksheet.getCells().get("A1").putValue(50);
//Adding a sample value to "A2" cell
worksheet.getCells().get("A2").putValue(-100);
//Adding a sample value to "A3" cell
worksheet.getCells().get("A3").putValue(150);
//Adding a chart to the worksheet
int chartIndex = worksheet.getCharts().add(ChartType.COLUMN, 5, 0, 15, 5);
//Accessing the instance of the newly added chart
Chart chart = worksheet.getCharts().get(chartIndex);
//Adding NSeries (chart data source) to the chart ranging from "A1" cell to "A3"
chart.getNSeries().add("A1:A3", true);
chart.getNSeries().get(0).getArea().setInvertIfNegative(true);
//Setting the foreground color of the 1st NSeries area
chart.getNSeries().get(0).getArea().setForegroundColor(Color.getRed());
//Setting the background color of the 1st NSeries area.
//The displayed area color of second chart point will be the background color.
chart.getNSeries().get(0).getArea().setBackgroundColor(Color.getYellow());
//Saving the Excel file
workbook.save("book1.xls");
