All Superinterfaces:

Dataset, SeriesDataset, XYDataset

All Known Implementing Classes:

CombinedDataset, DefaultHighLowDataset, SubSeriesDataset

public interface HighLowDataset
extends XYDataset

An interface that defines data in the form of (x, high, low, open, close) tuples.

Example: JFreeChart used this interface to obtain data for high-low-open-close plots.

Method Summary

java.lang.Number	getCloseValue(int series, int item) Returns the y-value for the specified series and item.
java.lang.Number	getHighValue(int series, int item) Returns the high-value for the specified series and item.
java.lang.Number	getLowValue(int series, int item) Returns the low-value for the specified series and item.
java.lang.Number	getOpenValue(int series, int item) Returns the open-value for the specified series and item.
java.lang.Number	getVolumeValue(int series, int item) Returns the volume for the specified series and item.
