条形图使用aChartEngine设置dsiplay图表值

我创建了一个动态条形图布局。在按钮上单击图表重新绘制。所以一切都很好，但我有一个问题，即setDisplayChartValues不仅显示当前的图表高度，而且还会显示之前高度的值。条形图使用aChartEngine设置dsiplay图表值

我找到了解决办法，代码更新

所以我第一次喜欢@ashoke告诉我。我说：

renderer = new XYSeriesRenderer(); 
dataset = new XYMultipleSeriesDataset(); 
mRenderer = new XYMultipleSeriesRenderer();

后，酒吧没有再出现。

所以我改变了我的onClick方法中的if语句：我在视图不存在的情况下添加了第一个if语句。之后，图表被添加并在第二个表格中被重新绘制。

if(mChartView == null){ 

       mChartView = ChartFactory.getBarChartView(getActivity(), dataset, mRenderer, Type.STACKED); 
       chartContainer.addView(mChartView); 
      } 

      if (mChartView != null) { 
       chartContainer.removeView(mChartView); 

       mChartView = ChartFactory.getBarChartView(getActivity(), dataset, mRenderer, Type.STACKED); 

       mChartView.repaint(); 
       chartContainer.addView(mChartView);// to refresh the graph 

       }

要在同一渲染和数据集对象重新使用。添加以下到您的onclick方法

renderer = new XYSeriesRenderer(); 
dataset = new XYMultipleSeriesDataset(); 
mRenderer = new XYMultipleSeriesRenderer();

年初这将创建新的渲染和数据集单击该按钮每次对象。或者，在添加新标签之前，您可以尝试在onClick中拨打clearXTextLabels and clearYTextLabels。
