Document

Creates a CategoryDataset that contains a copy of the data in an array (instances of Double are created to represent the data items).

Usage

From source file:org.eclipse.mylyn.tests.chart.ChartTest.java

public static CategoryDataset createCategoryDataset() {

    final double[][] data = new double[][] { { 10.0, 4.0, 15.0, 14.0, 0, 0, 0 },
            { 5.0, 7.0, 14.0, 3.0, 0, 0, 0 }, { 6.0, 17.0, 12.0, 7.0, 0, 0, 0 } };

    String[] measurements = { "navigating", "editing", "other" };
    String[] days = { "mon", "tue", "wed", "thu", "fri", "sat", "sun" };

    return DatasetUtilities.createCategoryDataset(measurements, days, data);
