public interface JRChartDataset

Datasets are used to represent the actual data needed to generate a chart. The dataset structure may vary with each chart type. This is the superinterface for all datasets and contains common dataset properties.

Method Detail

getResetType

byte getResetType()

Gets the reset type. This specifies the range of report data used for filling the dataset.

Returns:

one of the reset constants in JRVariable

getResetGroup

JRGroup getResetGroup()

Gets the selected reset group in case of reset type group.

getIncrementType

byte getIncrementType()

Returns the increment type. This specifies dataset values increment step.

Returns:

one of the reset constants in JRVariable, since the increment type uses the same constants as the reset type.

getIncrementGroup

JRGroup getIncrementGroup()

Gets the selected increment group in case of increment type group.

getDatasetType

byte getDatasetType()

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

collectExpressions

void collectExpressions(JRExpressionCollector collector)
