public Series generateSampledSeries(long length) {
    final Series newSeries = new Series(origin, Type.WATER);
    newSeries.setStepped(true);/*w w  w .  ja va 2s . c  o  m*/
    final int itemsCount = getItemCount();
    final ArrayList<Item> newItems = newSeries.items;
    double bufferValue = 0D;
    DateRange range = getRange();
    long lastStartBuffer = range.getLowerMillis();
    newItems.add(new Item(newSeries, new Date(lastStartBuffer), 0.0));
    for (int i = 1; i < itemsCount; i++) {
        final Item originalItem = items.get(i), previousOriginalItem = items.get(i - 1);
        if (lastStartBuffer + length <= originalItem.getDate().getTime()) {
            newItems.add(new Item(newSeries, new Date(lastStartBuffer), bufferValue));

                lastStartBuffer = time - ((originalItem.getDate().getTime() - lastStartBuffer) % length);
