Method Detail

init

public void init(JRFillChart chart)

Initializes the chart customizer.

Parameters:

chart - the fill chart object

getParameterValue

protected final Object getParameterValue(String parameterName)

Returns the value of a report parameter.

Parameters:

parameterName - the parameter name

Returns:

the value of a report parameter

getParameterValue

protected final Object getParameterValue(String parameterName,
                                         boolean fromInputDataset)

Returns the value of a report or input dataset parameter.

The input dataset differs from the report dataset when the chart uses a sub dataset as input.

Parameters:

parameterName - the parameter name

fromInputDataset - whether the parameter belongs to the input dataset rather than the report.

This is usefull only when the chart uses a sub dataset as input.

Returns:

the value of the parameter

getVariableValue

protected final Object getVariableValue(String variableName)

Returns the value of a report variable.

Parameters:

variableName - the variable name

Returns:

the value of a report variable

getVariableValue

protected final Object getVariableValue(String variableName,
                                        boolean fromInputDataset)

Returns the value of a report or input dataset variable.

The input dataset differs from the report dataset when the chart uses a sub dataset as input.

Parameters:

variableName - the variable name

fromInputDataset - whether the variable belongs to the input dataset rather than the report.

This is usefull only when the chart uses a sub dataset as input.

Returns:

the value of the variable

getFieldValue

protected final Object getFieldValue(String fieldName)

Returns the value of a report field.

Parameters:

fieldName - the field name

Returns:

the value of a report field

getFieldValue

protected final Object getFieldValue(String fieldName,
                                     boolean fromInputDataset)

Returns the value of a report or input dataset field.

The input dataset differs from the report dataset when the chart uses a sub dataset as input.

Parameters:

fieldName - the field name

fromInputDataset - whether the field belongs to the input dataset rather than the report.

This is usefull only when the chart uses a sub dataset as input.

Returns:
