Examples of org.jfree.data.general.Dataset

org.jfree.data.general.Dataset
The base interface for data sets.
All datasets are required to support the {@link DatasetChangeEvent}mechanism by allowing listeners to register and receive notification of any changes to the dataset.
In addition, all datasets must belong to one (and only one) {@link DatasetGroup}. The group object maintains a reader-writer lock which provides synchronised access to the datasets in multi-threaded code.
