### Question:
CandlestickChart { public static void main(String[] args) { BarSeries series = CsvTradesLoader.loadBitstampSeries(); OHLCDataset ohlcDataset = createOHLCDataset(series); TimeSeriesCollection xyDataset = createAdditionalDataset(series); JFreeChart chart = ChartFactory.createCandlestickChart("Bitstamp BTC price", "Time", "USD", ohlcDataset, true); CandlestickRenderer renderer = new CandlestickRenderer(); renderer.setAutoWidthMethod(CandlestickRenderer.WIDTHMETHOD_SMALLEST); XYPlot plot = chart.getXYPlot(); plot.setRenderer(renderer); int index = 1; plot.setDataset(index, xyDataset); plot.mapDatasetToRangeAxis(index, 0); XYLineAndShapeRenderer renderer2 = new XYLineAndShapeRenderer(true, false); renderer2.setSeriesPaint(index, Color.blue); plot.setRenderer(index, renderer2); plot.setRangeGridlinePaint(Color.lightGray); plot.setBackgroundPaint(Color.white); NumberAxis numberAxis = (NumberAxis) plot.getRangeAxis(); numberAxis.setAutoRangeIncludesZero(false); plot.setDatasetRenderingOrder(DatasetRenderingOrder.FORWARD); displayChart(chart); }  static void main(String[] args);  }### Answer:
@Test public void test() { CandlestickChart.main(null); }
