Interface HighLowDataset

All Superinterfaces:
Dataset, SeriesDataset, XYDataset
All Known Implementing Classes:
CombinedDataset, DefaultHighLowDataset, OHLCDataset, 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.
