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，但是我遇到的问题是setDisplayChartValues不仅显示当前的图表高度，还会显示之前高度的值。
我找到了解决方案，代码已更新

所以我首先喜欢@ashoke告诉我。我补充说：
renderer = new XYSeriesRenderer();
dataset = new XYMultipleSeriesDataset();
mRenderer = new XYMultipleSeriesRenderer();
所以我改变了onClick方法中的if语句： 我添加了第一个if语句，以防View不存在。之后，图表被添加，并在第二个参数中重新绘制。
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
}

您正在重复使用相同的渲染器和数据集对象。将以下内容添加到onclick方法的开头
renderer = new XYSeriesRenderer();
dataset = new XYMultipleSeriesDataset();
mRenderer = new XYMultipleSeriesRenderer();
每次单击按钮时，都会创建新的渲染器和数据集对象。或者，您可以在添加新标签之前尝试拨打onClick中的clearXTextLabels and clearYTextLabels。
