Description

Interface Summary
BoxAndWhiskerCategoryDataset: A category dataset that defines various medians, outliers and an average value for each item.
BoxAndWhiskerXYDataset: An interface that defines data in the form of (x, max, min, average, median) tuples.
MultiValueCategoryDataset: A category dataset that defines multiple values for each item.
StatisticalCategoryDataset: A category dataset that defines a median and standard deviation value for each item.

Class Summary
BoxAndWhiskerCalculator: A utility class that calculates the mean, median, quartiles Q1 and Q3, plus a list of outlier values...all from an arbitrary list of `Number` objects.
BoxAndWhiskerItem: Represents one data item within a box-and-whisker dataset.
DefaultBoxAndWhiskerCategoryDataset: A convenience class that provides a default implementation of the `BoxAndWhiskerCategoryDataset` interface.
DefaultBoxAndWhiskerXYDataset: A simple implementation of the `BoxAndWhiskerXYDataset` interface.
DefaultMultiValueCategoryDataset: A category dataset that defines multiple values for each item.
DefaultStatisticalCategoryDataset: A convenience class that provides a default implementation of the `StatisticalCategoryDataset` interface.
HistogramBin: A bin for the `HistogramDataset` class.
HistogramDataset: A dataset that can be used for creating histograms.
HistogramType: A class for creating constants to represent the histogram type.
MeanAndStandardDeviation: A simple data structure that holds a mean value and a standard deviation value.
Regression: A utility class for fitting regression curves to data.
SimpleHistogramBin: A bin for the `SimpleHistogramDataset`.
SimpleHistogramDataset: A dataset used for creating simple histograms with custom defined bins.
