ChartYValue
Inheritance: java.lang.Object
public class ChartYValue
Represents an Y value for a chart series.
Remarks:
This class contains a number of static methods for creating an Y value of a particular type. The getValueType() property allows you to determine the type of an existing Y value.
All non-null Y values of a chart series must be of the same ChartYValueType type.
Methods
| Method | Description |
|---|---|
| equals(Object obj) | Gets a flag indicating whether the specified object is equal to the current Y value object. |
| fromDateTime(Date value) | Creates a ChartYValue instance of the ChartYValueType.DATE_TIME type. |
| fromDouble(double value) | Creates a ChartYValue instance of the ChartYValueType.DOUBLE type. |
| fromTimeSpan(long value) | Creates a ChartYValue instance of the ChartYValueType.TIME type. |
| getDateTimeValue() | Gets the stored datetime value. |
| getDoubleValue() | Gets the stored numeric value. |
| getTimeValue() | Gets the stored time value. |
| getValueType() | Gets the type of the Y value stored in the object. |
| hashCode() |

Parameters:
| Parameter | Type | Description |
|---|---|---|
| obj | java.lang.Object |
Returns: boolean
fromDateTime(Date value)
public static ChartYValue fromDateTime(Date value)

Parameters:
| Parameter | Type | Description |

Examples:
Shows how to populate chart series with data.
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder();
Shape shape = builder.insertChart(ChartType.COLUMN, 432.0, 252.0);
Chart chart = shape.getChart();
ChartSeries series1 = chart.getSeries().get(0);
// Clear X and Y values of the first series.
series1.clearValues();
// Populate the series with data.
series1.add(ChartXValue.fromDouble(3.0), ChartYValue.fromDouble(10.0));
series1.add(ChartXValue.fromDouble(5.0), ChartYValue.fromDouble(5.0));
series1.add(ChartXValue.fromDouble(7.0), ChartYValue.fromDouble(11.0));
series1.add(ChartXValue.fromDouble(9.0), ChartYValue.fromDouble(17.0));
ChartSeries series2 = chart.getSeries().get(1);
// Clear X and Y values of the second series.
series2.clearValues();
// Populate the series with data.
series2.add(ChartXValue.fromDouble(2.0), ChartYValue.fromDouble(4.0));
series2.add(ChartXValue.fromDouble(4.0), ChartYValue.fromDouble(7.0));
series2.add(ChartXValue.fromDouble(6.0), ChartYValue.fromDouble(14.0));
series2.add(ChartXValue.fromDouble(8.0), ChartYValue.fromDouble(7.0));
