Interface ContourDataset

All Superinterfaces:
  Dataset, SeriesDataset, XYDataset, XYZDataset

All Known Implementing Classes:
  DefaultContourDataset, NonGridContourDataset

Deprecated. This interface is no longer supported (as of version 1.0.4). If you are creating contour plots, please try to use `XYPlot` and `XYBlockRenderer`.

    public interface ContourDataset

extends XYZDataset

The interface through which JFreeChart obtains data in the form of (x, y, z) items - used for XY and XYZ plots.
