• org.jfree.data.xy: Javadoc index of package org.jfree.data.xy.


Package Samples:

• org.jfree.data.xy.junit: A package containing the XYDataset interface and related classes.  

Classes:

• CategoryTableXYDataset: An implementation variant of the TableXYDataset where every series shares the same x-values (required for generating stacked area charts). This implementation uses a org.jfree.data.DefaultKeyedValues2D Object as backend implementation and is hence more "category oriented" than the DefaultTableXYDataset implementation. This implementation provides no means to remove data items yet. This is due to the lack of such facility in the DefaultKeyedValues2D class. This class also implements the IntervalXYDataset interface, but this implementation is provisional.
• IntervalXYDelegate: A class for delegating xy-interval issues to. Enhances a XYDataset to an XYIntervalDataset. The decorator pattern was not used because of the several possibly implemented interfaces of the decorated instance (e.g. TableXYDataset, RangeInfo, DomainInfo etc.). This class calculates the minimal interval width between two items. This width influences the width of bars displayed with this dataset. The width can be set manually or calculated automatically. The switch autoWidth allows to determine which behavior is used. The behavior is transparent: The width is always calculated automatically in the ...
• XYDatasetTableModel: A READ-ONLY wrapper around a TableXYDataset to convert it to a table model for use in a JTable. The first column of the table shows the x-values, the remaining columns show the y-values for each series (series 0 appears in column 1, series 1 appears in column 2, etc). TO DO: implement proper naming for x axis (getColumnName) implement setValueAt to remove READ-ONLY constraint (not sure how)
• 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 XYDataset interface (which allows independent x-values between series). This is used primarily by the org.jfree.chart.renderer.xy.StackedXYAreaRenderer .
• XYSeries: Represents a sequence of zero or more data items in the form (x, y). By default, items in the series will be sorted into ascending order by x-value, and duplicate x-values are permitted. Both the sorting and duplicate defaults can be changed in the constructor. Y-values can be null to represent missing values.
• IntervalXYDataset: An extension of the XYDataset interface that allows a range of data to be defined for the X values, the Y values, or both the X and Y values. This interface is used to support (among other things) bar plots against numerical axes.
• XYBarDataset: A dataset wrapper class that converts a standard XYDataset into an IntervalXYDataset suitable for use in creating XY bar charts.
• OHLCDataItem: Represents a single (open-high-low-close) data item in an DefaultOHLCDataset . This data item is commonly used to summarise the trading activity of a financial commodity for a fixed period (most often one day).
• NormalizedMatrixSeries: Represents a dense normalized matrix M[i,j] where each Mij item of the matrix has a value (default is 0). When a matrix item is observed using getItem method, it is normalized, that is, divided by the total sum of all items. It can be also be scaled by setting a scale factor.
• IntervalXYZDataset: An extension of the XYZDataset interface that allows a range of data to be defined for any of the X values, the Y values, and the Z values.
• DefaultTableXYDataset: An XYDataset where every series shares the same x-values (required for generating stacked area charts).
• DefaultOHLCDataset: A simple implementation of the OHLCDataset interface. This implementation supports only one series.
• DataXYPackageTests: Some tests for the org.jfree.data.category package that can be run using JUnit. You can find more information about JUnit at http://www.junit.org .
• AbstractXYZDataset: An base class that you can use to create new implementations of the XYZDataset interface.
• AbstractIntervalXYDataset: An base class that you can use to create new implementations of the org.jfree.data.xy.IntervalXYDataset interface.
• MatrixSeriesCollection: Represents a collection of MatrixSeries that can be used as a dataset.
• XYSeriesCollection: Represents a collection of XYSeries objects that can be used as a dataset.
• AbstractXYDataset: An base class that you can use to create new implementations of the org.jfree.data.xy.XYDataset interface.
• SignalsDataset: An interface that adds signal information to an XYDataset .
• DefaultWindDataset: A default implementation of the WindDataset interface.
• DefaultHighLowDataset: A simple implementation of the OHLCDataset .
• XYDataItem: Represents one (x, y) data item for an XYSeries .
• DefaultTableXYDatasetTests: Tests for the org.jfree.data.xy.DefaultTableXYDataset class.
• IntervalXYDelegateTests: Some checks for the org.jfree.data.xy.IntervalXYDelegate class.
• XYSeriesCollectionTests: Tests for the org.jfree.data.xy.XYSeriesCollection class.
