android – 如何使用AchartEngine在折线图中设置x轴上的日期？

我已尝试在SO上发布各种链接,但没有得到可靠的答案.

这是我的代码：

 TimeSeries series = new TimeSeries("Burned Calories");

    for (int i = 0; i < x_axis.size(); i++) {

            String date = x_axis.get(i);

            int y = Integer.parseInt(y_axis.get(i));

            Date d;

            try {

                    d = df.parse(date);

                    series.add(d, y);

            } catch (ParseException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

            }

      XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();

      dataset.addSeries(series);

XYSeriesRenderer render = new XYSeriesRenderer();
    render.setColor(Color.GREEN);
render.setPointStyle(PointStyle.SQUARE);
render.setFillPoints(true);

      XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
  renderer.addSeriesRenderer(render);

        renderer.setChartTitle("Line Chart");
    renderer.setAxesColor(Color.BLUE);
    renderer.setGridColor(Color.WHITE);

    renderer.setShowGrid(true);
    renderer.setShowAxes(true);
    renderer.setShowGridX(true);
    renderer.setShowGridY(true);
    renderer.setShowLabels(true);
    renderer.setPanEnabled(true, true);
    renderer.setFitLegend(true);
    renderer.setXTitle("Date");
    renderer.setAxisTitleTextSize(15);
    renderer.setXLabelsAlign(Align.CENTER);
    renderer.setYTitle("Values");

    chart = ChartFactory.getLineChartView(this, dataset, renderer);

我在x轴上得到奇怪的值.

任何帮助,将不胜感激.

解决方法:

这些是我在我的代码中所做的基本更改,它对我有用..

TimeSeries series2 = new TimeSeries("Protein");

            for (int i = 0; i < x_axis.size(); i++) {

                int y = Integer.parseInt(y1_axis.get(i));

                // Adding y as protein value
                series2.add(i + 1, y);

            }


    for (int i = 0; i < x_axis.size(); i++) {
        renderer.addXTextLabel(i + 1, x_axis.get(i));
    }

    renderer.setXLabels(0);
