图表值未正确显示堆栈条形图achartengine

Question

我正在使用Achartengine库创建Stacked条形图。值未正确显示。我想要在条形图顶部显示如此{20,20,20}的图表值并与中心对齐。

这是我的代码

    dataset.addSeries(JumlahSeries);
    dataset.addSeries(JumlahSeries1);
    dataset.addSeries(FirstSeries);
    final XYSeriesRenderer FirstRenderer = new XYSeriesRenderer();
    Log.d("Error Here","29");
    FirstRenderer.setColor(Color.BLUE);
    FirstRenderer.setFillPoints(false);
    FirstRenderer.setLineWidth(5);  
    FirstRenderer.setChartValuesTextSize(15);
    FirstRenderer.setDisplayChartValues(false);

            // Creating XYSeriesRenderer to customize expenseSeries
    Log.d("Error Here","30");
    final XYSeriesRenderer SecondRenderer = new XYSeriesRenderer();
    SecondRenderer.setColor(Color.RED);
    SecondRenderer.setFillPoints(false);
    SecondRenderer.setLineWidth(5);
    SecondRenderer.setDisplayChartValues(false);
    SecondRenderer.setChartValuesTextSize(15);
    Log.d("Error Here","31");
    final XYSeriesRenderer ThirdRenderer = new XYSeriesRenderer();
    ThirdRenderer.setFillPoints(false);
    ThirdRenderer.setColor(Color.GREEN);
    ThirdRenderer.setLineWidth(5);
    ThirdRenderer.setDisplayChartValues(false);
    ThirdRenderer.setChartValuesTextSize(15);
    // Creating a XYMultipleSeriesRenderer to customize the whole chart
    final XYMultipleSeriesRenderer multiRenderer = new XYMultipleSeriesRenderer();
    //zoomIn = new Zoom((GraphicalView) mChart, true, multiRenderer.getZoomRate());
    //multiRenderer.setChartTitle("\n"+"\n"+ title);
