org.jfree.data.Values2D

Packages that use Values2D
org.jfree.data: The base package for classes that represent various types of data.
org.jfree.data.category: A package containing the `CategoryDataset` interface and related classes.
org.jfree.data.gantt: Data interfaces and classes for Gantt charts.
org.jfree.data.general: Data interfaces and classes.

Uses of Values2D in org.jfree.data

Subinterfaces of Values2D in org.jfree.data
`interface` `KeyedValues2D` An extension of the `Values2D` interface where a unique key is associated with the row and column indices.

Classes in org.jfree.data that implement Values2D
`class` `DefaultKeyedValues2D` A data structure that stores zero, one or many values, where each value is associated with two keys (a 'row' key and a 'column' key).

Methods in org.jfree.data with parameters of type Values2D
`static double` `DataUtilities.calculateColumnTotal(Values2D data, int column)` Returns the total of the values in one column of the supplied data table.
`static double` `DataUtilities.calculateColumnTotal(Values2D data, int column, int[] validRows)` Returns the total of the values in one column of the supplied data table by taking only the row numbers in the array into account.
`static double` `DataUtilities.calculateRowTotal(Values2D data, int row)` Returns the total of the values in one row of the supplied data table.
`static double` `DataUtilities.calculateRowTotal(Values2D data, int row, int[] validCols)` Returns the total of the values in one row of the supplied data table by taking only the column numbers in the array into account.

Uses of Values2D in org.jfree.data.category

Subinterfaces of Values2D in org.jfree.data.category
`interface` `CategoryDataset` The interface for a dataset with one or more series, and values associated with categories.
`interface` `IntervalCategoryDataset` A category dataset that defines a value range for each series/category combination.

Classes in org.jfree.data.category that implement Values2D
`class` `DefaultCategoryDataset` A default implementation of the `CategoryDataset` interface.
`class` `DefaultIntervalCategoryDataset` A convenience class that provides a default implementation of the `IntervalCategoryDataset` interface.
`class` `SlidingCategoryDataset` A `CategoryDataset` implementation that presents a subset of the categories in an underlying dataset.

Uses of Values2D in org.jfree.data.gantt

Subinterfaces of Values2D in org.jfree.data.gantt
`interface` `GanttCategoryDataset` An extension of the `IntervalCategoryDataset` interface that adds support for multiple sub-intervals.

Classes in org.jfree.data.gantt that implement Values2D
`class` `SlidingGanttCategoryDataset` A `GanttCategoryDataset` implementation that presents a subset of the categories in an underlying dataset.
`class` `TaskSeriesCollection` A collection of `TaskSeries` objects.

Uses of Values2D in org.jfree.data.general

Subinterfaces of Values2D in org.jfree.data.general
`interface` `KeyedValues2DDataset` A dataset containing (key, value) data items.

Classes in org.jfree.data.general that implement Values2D
`class` `DefaultKeyedValues2DDataset` A default implementation of the `KeyedValues2DDataset` interface.

Uses of Values2D in org.jfree.data.jdbc

Classes in org.jfree.data.jdbc that implement Values2D
`class` `JDBCCategoryDataset` A `CategoryDataset` implementation over a database JDBC result set.

Uses of Values2D in org.jfree.data.statistics

Subinterfaces of Values2D in org.jfree.data.statistics
`interface` `BoxAndWhiskerCategoryDataset` A category dataset that defines various medians, outliers and an average value for each item.
`interface` `MultiValueCategoryDataset` A category dataset that defines multiple values for each item.
`interface` `StatisticalCategoryDataset` A category dataset that defines a mean and standard deviation value for each item.

Classes in org.jfree.data.statistics that implement Values2D
`class` `DefaultBoxAndWhiskerCategoryDataset` A convenience class that provides a default implementation of the `BoxAndWhiskerCategoryDataset` interface.
`class` `DefaultMultiValueCategoryDataset` A category dataset that defines multiple values for each item.
`class` `DefaultStatisticalCategoryDataset` A convenience class that provides a default implementation of the `StatisticalCategoryDataset` interface.
