Question

使用achartengine，我需要在时间图上显示值。根据我放置命令行的位置，不显示任何值或显示错误值。我想这是因为List在库中的使用方式（排序），但我不知道如何处理它。

以下是代码：

public GraphicalView getViewTime(Context context, int spinnerSelection, List<myObject> myDataSrc) {

    // *********************
    // SET Graphical objects
    // *********************
    XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
    XYMultipleSeriesDataset mDataSet = new XYMultipleSeriesDataset();

    // **************
    // AUTOSCALING
    // **************
    AutoScaling<E> AutoScaled = new AutoScaling<E>(spinnerSelection, myDataSrc);

    // *************
    // mdataset
    // *************
    List<Date[]> X_serie = AutoScaled.getXserie();
    List<double[]> Y_serie = AutoScaled.getYserie();

    String[] titles = new String[] { ""/* spinnerSelection */};
    mDataSet = buildDateDataset(titles, X_serie, Y_serie);


    // **************
    // mRenderers
    // **************
    // LEGENDS
    String ChartTitle = getTitle(context, spinnerSelection);
    //mRenderer.setDisplayChartValues(true);

    setChartSettings(mRenderer, ChartTitle, XlegendText, YlegendText, AutoScaled.getFirstRecordDate(), AutoScaled.getLastRecordDate(), 0.0, AutoScaled.getYmax(),
                Color.GRAY, Color.LTGRAY);

    // if command line is here, no values are shown
    // mRenderer.setDisplayChartValues(true);

    // LABELS
    mRenderer.setYLabels(YlabelsCount);
    mRenderer.setXLabels(XlabelsCount);
    mRenderer.setShowLabels(true);
    mRenderer.setXLabelsAlign(Align.RIGHT);
    // renderer.setXLabelsAngle(270L);
    mRenderer.setYLabelsAlign(Align.RIGHT);

    // COLORS
    int[] Colors = new int[] { curveColors[spinnerSelection] };
    mRenderer = buildRenderer(Colors, styles);

     // Shows values at the wrong "place", like random because of List I guess
    // mRenderer.setDisplayChartValues(true);

    // ZOOM
    double[] panLimits = AutoScaled.getPanLimits();
    mRenderer.setZoomEnabled(XenabledZoom, YenabledZoom);
    mRenderer.setZoomButtonsVisible(showZoomButtons);
    mRenderer.setZoomRate(ZoomRate);
    mRenderer.setPanLimits(panLimits);
    mRenderer.setZoomLimits(panLimits);

    // SHOW ONLY last WEEK even after Zoom reset
    mRenderer.setXAxisMin( AutoScaled.getDateOneWeekAgo() );
    mRenderer.setInitialRange(AutoScaled.getXYRange());

    // GRID
    mRenderer.setShowGrid(showGrid);

    // VIEW
    GraphicalView BasicView = ChartFactory.getTimeChartView(context, mDataSet, mRenderer, DateFormat);

    return BasicView;
}

编辑：即使在显示值的情况下，如果我将图表向左滑动，也会出现此致命错误：

11-15 14：55：54.746：E / AndroidRuntime（1555）： java.lang.ArrayIndexOutOfBoundsException：length = 135; index = -82 11-15 14：55：54.746：E / AndroidRuntime（1555）：at java.util.ArrayList.get（ArrayList.java:306）11-15 14：55：54.746： E / AndroidRuntime（1555）：at org.achartengine.util.IndexXYMap.getYByIndex（IndexXYMap.java:80)11-15 14：55：54.746：E / AndroidRuntime（1555）：at org.achartengine.model.XYSeries.getY（XYSeries.java:169)11-15 14：55：54.746：E / AndroidRuntime（1555）：at org.achartengine.chart.XYChart.drawChartValuesText（XYChart.java:539） 11-15 14：55：54.746：E / AndroidRuntime（1555）：at org.achartengine.chart.XYChart.drawSeries（XYChart.java:502)11-15 14：55：54.746：E / AndroidRuntime（1555）：at org.achartengine.chart.XYChart.draw（XYChart.java:286)11-15 14：55：54.746：E / AndroidRuntime（1555）：at org.achartengine.GraphicalView.onDraw（GraphicalView.java:166）

编辑2：代码中使用的值

int XlabelsCount = 7;
int YlabelsCount = 10;
float ZoomRate = 1.20f;
String DateFormat = "dd MMM yy\n HH:mm";
