Achartengine条形图在仿真器上正确绘制，而不是在设备上绘制

Question

我正在使用achartengine绘制条形图。它在仿真器上正确绘制，但不在实际设备上。有任何想法吗？这是我正在使用的代码。我从数据库中获取的字符串就像是2 4 5 8 9.它在模拟器上绘制得很好但在设备上没有。谢谢

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
         super.onCreate(savedInstanceState);
        setContentView(R.layout.graph);

          chart_container=(LinearLayout)findViewById(R.id.Chart_layout);
     myDatabase myDb = new myDatabase(this);
          myDb.open();
          String pull = myDb.getData();

          String see = pull.replaceAll("\\s+","");  

         int[] intArray = new int[see.length()];
         for(int k=0; k < see.length(); k++){

          intArray[k] = Character.digit(see.charAt(k), 10);

          }

CategorySeries series = new CategorySeries（＆＃34; My Graph＆＃34;）;               for（int i = 0; i＆lt; intArray.length; i ++）{

            series.add("Bar ", intArray[i]);
         }

XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset（）;              dataset.addSeries（series.toXYSeries（））;

XYSeriesRenderer renderer = new XYSeriesRenderer（）;               renderer.setDisplayChartValues（真）;               renderer.setColor（getResources（）的getColor（R.color.fuchsia））;

XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer（）;                mRenderer.addSeriesRenderer（渲染）;

LinearLayout chart_container =（LinearLayout）findViewById（R.id.Chart_layout）;

    mChart=(GraphicalView)ChartFactory.getBarChartView(getBaseContext(), dataset, mRenderer, Type.DEFAULT);
    chart_container.addView(mChart);
