org.apache.commons.math.stat.descriptive.DescriptiveStatistics.addValue()
Adds the value to the dataset. If the dataset is at the maximum size (i.e., the number of stored elements equals the currently configured windowSize), the first (oldest) element in the dataset is discarded to make room for the new value. @param v the value to be added

        for (SampleInfo bamQcResult : bamQCResults) {
            String path = rawDataDirs.get(bamQcResult) + File.separator + "coverage_across_reference.txt";
            XYVector rawData = loadColumnData(new File(path), 0, Double.MAX_VALUE, 1);
            XYVector scaledData = scaleXAxis(rawData);
