如何使用apache POI创建包含两个CategoryAxis的LineChart？

Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Chart");

Drawing<?> drawing = sheet.createDrawingPatriarch();
ClientAnchor anchor = drawing.createAnchor(0, 0, 0, 0, 0, 5, 10, 15);
Chart chart = drawing.createChart(anchor);

ChartAxis bottomAxis = chart.getChartAxisFactory().createCategoryAxis(AxisPosition.BOTTOM);
ChartAxis topAxis = chart.getChartAxisFactory().createCategoryAxis(AxisPosition.TOP);

bottomAxis.setCrosses(AxisCrosses.AUTO_ZERO);
bottomAxis.setMajorTickMark(AxisTickMark.CROSS);
bottomAxis.setMinorTickMark(AxisTickMark.OUT);
bottomAxis.setOrientation(AxisOrientation.MIN_MAX);
bottomAxis.setTitle("Bottom Axis");

topAxis.setCrosses(AxisCrosses.AUTO_ZERO);
topAxis.setMajorTickMark(AxisTickMark.CROSS);
topAxis.setMinorTickMark(AxisTickMark.OUT);
topAxis.setOrientation(AxisOrientation.MIN_MAX);
topAxis.setTitle("Top Axis");

LineChartData data = chart.getChartDataFactory().createLineChartData();
data.setCategoryAxis(bottomAxis);
data.addAxis(topAxis);

chart.plot(data);

FileOutputStream fileOut = new FileOutputStream("chart.xlsx");
workbook.write(fileOut);
fileOut.close();
