Android aCharEngine条形图XTEXT标签，条对齐

Im使用aChartEngine（1.2.0 jar）生成一个7条条形图

我有两个问题。 这些条未与其“addXTextLabel”对齐/居中。 当我增加条形图的宽度时，并非所有条形图都显示在图表上

唯一保持居中/与“XTextLabel”对齐的条是条4

这是我的密码

    //renderer7.setLineWidth((float) 50.0d);


    // This is how the "Graph" itself will look like
    XYMultipleSeriesRenderer mRenderer = new XYMultipleSeriesRenderer();
     mRenderer.setChartTitle("Performance");
     mRenderer.setYTitle("Rating");
     mRenderer.setChartTitleTextSize(25);
     mRenderer.setAxisTitleTextSize(25);
     mRenderer.setAxesColor(titleColor);
     mRenderer.setLabelsColor(titleColor);
     mRenderer.setApplyBackgroundColor(true);
     mRenderer.setBackgroundColor(background);
     mRenderer.setMarginsColor(background);
     mRenderer.setZoomEnabled(false,false);
     mRenderer.setPanEnabled(false,false);
     mRenderer.setMargins(new int[] { 20, 90, 15, 20 });
     mRenderer.setShowGridY(true);      
     mRenderer.setLabelsTextSize(15);
     mRenderer.setXLabels(0);
     mRenderer.setXAxisMin(0);
     mRenderer.setYAxisMin(0);
     mRenderer.setXAxisMax(8);
     mRenderer.setYAxisMax(100);
     mRenderer.addXTextLabel(1, "Bar 1");
     mRenderer.addXTextLabel(2, "Bar 2");
     mRenderer.addXTextLabel(3, "Bar 3");
     mRenderer.addXTextLabel(4, "Bar 4");
     mRenderer.addXTextLabel(5, "Bar 5");
     mRenderer.addXTextLabel(6, "Bar 6");
     mRenderer.addXTextLabel(7, "Bar 7");

     mRenderer.addSeriesRenderer(renderer);
     mRenderer.addSeriesRenderer(renderer2);
     mRenderer.addSeriesRenderer(renderer3);
     mRenderer.addSeriesRenderer(renderer4);
     mRenderer.addSeriesRenderer(renderer5);
     mRenderer.addSeriesRenderer(renderer6);
     mRenderer.addSeriesRenderer(renderer7);
     //mRenderer.setBarWidth(80);
     mRenderer.setBarSpacing(0);


    Intent intent = ChartFactory.getBarChartIntent(context, dataset,mRenderer, Type.DEFAULT);
    return intent;
  }

 }

所以，我试图实现的是让所有的条形图都显示在图表上，条形图的宽度为80，并且让XTEXTLABLE与每个对应的条形图对齐

提前感谢

所以我以前尝试过这个，但我似乎做了很多改变，尝试了不同的方法，我没有意识到这是有效的。因此，使用我上面发布的代码，我只需更改

mRenderer.setBarWidth(100);
mRenderer.setBarSpacing(-50);

Intent-Intent=ChartFactory.getBarChartIntent（上下文、数据集、mrender、Type.DEFAULT）

到

Intent-Intent=ChartFactory.getBarChartIntent（上下文、数据集、mrender、Type.STACKED）

我得到了我想要的结果
