Examples of org.jfree.data.statistics.HistogramDataset.addSeries()

org.jfree.data.statistics.HistogramDataset.addSeries()
Adds a series to the dataset, using the specified number of bins, and sends a {@link DatasetChangeEvent} to all registered listeners. @param key the series key (null not permitted). @param values the values (null not permitted). @param bins the number of bins (must be at least 1).

        for (int i = 0; i < doubleNumbers.length; i++) {
            doubleNumbers[i] = numbers[i].doubleValue();
        }


        dataset.addSeries(dataName, doubleNumbers, divisions > 0 ? divisions : 10);//Use 10 divisions if divisions number is invalid.
