Constructor Detail

JRDesignHighLowDataset

public JRDesignHighLowDataset(JRChartDataset dataset)

Method Detail

getSeriesExpression

public JRExpression getSeriesExpression()

Specified by:

getSeriesExpression in interface JRHighLowDataset

Returns:

the expression of the series name. Currently only one series is supported inside a High-Low or Candlestick chart. This limitation is documented inside JFreeChart, the library used for the built-in chart support. However, this single series must be identified by a java.lang.Comparable value returned by this expression, and it must also be used as the series name in the chart's legend.

setSeriesExpression

public void setSeriesExpression(JRExpression seriesExpression)

getDateExpression

public JRExpression getDateExpression()

Specified by:

getDateExpression in interface JRHighLowDataset

Returns:

the expression of the date to which the current (high, low, open, close, volume) item refers.

setDateExpression

public void setDateExpression(JRExpression dateExpression)

getHighExpression

public JRExpression getHighExpression()

Specified by:

getHighExpression in interface JRHighLowDataset

Returns:

a numeric expression that will be part of the data item added to the series when the dataset gets incremented.

setHighExpression

public void setHighExpression(JRExpression highExpression)

getLowExpression

public JRExpression getLowExpression()

Specified by:

getLowExpression in interface JRHighLowDataset

Returns:

a numeric expression that will be part of the data item added to the series when the dataset gets incremented.

setLowExpression

public void setLowExpression(JRExpression lowExpression)

getOpenExpression

public JRExpression getOpenExpression()

Specified by:

getOpenExpression in interface JRHighLowDataset

Returns:

a numeric expression that will be part of the data item added to the series when the dataset gets incremented.

setOpenExpression

public void setOpenExpression(JRExpression openExpression)

getCloseExpression

public JRExpression getCloseExpression()

Specified by:

getCloseExpression in interface JRHighLowDataset

Returns:

a numeric expression that will be part of the data item added to the series when the dataset gets incremented.

setCloseExpression

public void setCloseExpression(JRExpression closeExpression)

getVolumeExpression

public JRExpression getVolumeExpression()

Specified by:

getVolumeExpression in interface JRHighLowDataset

Returns:

a numeric expression representing the volume value to use for the current data item. It is used only for Candlestick charts.

setVolumeExpression

public void setVolumeExpression(JRExpression volumeExpression)

getDatasetType

public byte getDatasetType()

Description copied from interface: JRChartDataset

Gets the dataset type. Must be one of the dataset type constants defined in this class.

Specified by:

getDatasetType in interface JRChartDataset

Overrides:

getDatasetType in class JRDesignChartDataset

collectExpressions

public void collectExpressions(JRExpressionCollector collector)

Specified by:

collectExpressions in interface JRElementDataset

Overrides:

collectExpressions in class JRBaseElementDataset

collectExpressions

public void collectExpressions(ChartsExpressionCollector collector)

Specified by:

collectExpressions in interface JRChartDataset

getItemHyperlink

public JRHyperlink getItemHyperlink()

Description copied from interface: JRHighLowDataset

Returns the hyperlink specification for chart items.

The hyperlink will be evaluated for every chart item and a image map will be created for the chart.

Specified by:

getItemHyperlink in interface JRHighLowDataset

Returns:

hyperlink specification for chart items

setItemHyperlink

public void setItemHyperlink(JRHyperlink itemHyperlink)

Sets the hyperlink specification for chart items.

Parameters:

itemHyperlink - the hyperlink specification

See Also:

getItemHyperlink()

validate

public void validate(ChartsVerifier verifier)

Description copied from interface: JRChartDataset

Validates the dataset using a verifier.

Broken rules are collected by the verifier.

Specified by:

validate in interface JRChartDataset

Parameters:

verifier - the verifier to use for validation

clone

public Object clone()

Specified by:

clone in interface JRCloneable

Overrides:

clone in class JRDesignElementDataset
