  public AxisDisplayUnit()

Property Getters/Setters Detail

• getCustomUnit/setCustomUnit

  public double getCustomUnit() / public void setCustomUnit(double value)
  

  Gets or sets a user-defined divisor to scale display units on the value axis.

  The property is not supported by MS Office 2016 new charts. Default value is 1.

  Setting this property sets the Unit property to AxisBuiltInUnit.CUSTOM.

  Example:

  Shows how to manipulate the tick marks and displayed values of a chart axis.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  Shape shape = builder.insertChart(ChartType.SCATTER, 450.0, 250.0);
  Chart chart = shape.getChart();
  
  Assert.assertEquals(1, chart.getSeries().getCount());
  Assert.assertEquals("Y-Values", chart.getSeries().get(0).getName());
  
  // Set the minor tick marks of the Y-axis to point away from the plot area,
  // and the major tick marks to cross the axis.
  ChartAxis axis = chart.getAxisY();
  axis.setMajorTickMark(AxisTickMark.CROSS);
  axis.setMinorTickMark(AxisTickMark.OUTSIDE);
  
  // Set they Y-axis to show a major tick every 10 units, and a minor tick every 1 unit.
  axis.setMajorUnit(10.0);
  axis.setMinorUnit(1.0);
  
  // Set the Y-axis bounds to -10 and 20.
  // This Y-axis will now display 4 major tick marks and 27 minor tick marks.
  axis.getScaling().setMinimum(new AxisBound(-10));
  axis.getScaling().setMaximum(new AxisBound(20.0));
  
  // For the X-axis, set the major tick marks at every 10 units,
  // every minor tick mark at 2.5 units, and configure them to both be inside the graph plot area.
  axis = chart.getAxisX();
  axis.setMajorTickMark(AxisTickMark.INSIDE);
  axis.setMinorTickMark(AxisTickMark.INSIDE);
  axis.setMajorUnit(10.0);
  axis.setMinorUnit(2.5);
  
  // Set the X-axis bounds so that the X-axis spans 5 major tick marks and 12 minor tick marks.
  axis.getScaling().setMinimum(new AxisBound(-10));
  axis.getScaling().setMaximum(new AxisBound(30.0));
  axis.setTickLabelAlignment(ParagraphAlignment.RIGHT);
  
  Assert.assertEquals(1, axis.getTickLabelSpacing());
  
  // Set the tick labels to display their value in millions.
  axis.getDisplayUnit().setUnit(AxisBuiltInUnit.MILLIONS);
  
  // We can set a more specific value by which tick labels will display their values.
  // This statement is equivalent to the one above.
  axis.getDisplayUnit().setCustomUnit(1000000.0);
  
  doc.save(getArtifactsDir() + "Charts.AxisDisplayUnit.docx");

• getDocument

  public DocumentBase getDocument()
  

  Returns the Document the title holder belongs.

• getUnit/setUnit

  public int getUnit() / public void setUnit(int value)
  

  Gets or sets the scaling value of the display units as one of the predefined values. The value of the property is AxisBuiltInUnit integer constant.

  Default value is AxisBuiltInUnit.NONE. The AxisBuiltInUnit.CUSTOM and AxisBuiltInUnit.PERCENTAGE values are not available in some chart types; see AxisBuiltInUnit for more information.
