Examples of org.jfree.data.xy.TableXYDataset

org.jfree.data.xy.TableXYDataset
A dataset containing one or more data series containing (x, y) data items, where all series in the dataset share the same set of x-values. This is a restricted form of the {@link XYDataset} interface (which allows independentx-values between series). This is used primarily by the {@link org.jfree.chart.renderer.xy.StackedXYAreaRenderer}.
