所有栏都显示在MPAndroidChart中的相同位置

Question

我正在使用MPAndroidChart library。

performance= result.getJSONArray("performance");
            for(int i = 0; i<performance.length();i++){
                JSONObject jsonChildNode = performance.getJSONObject(i);

                Iterator iterator = jsonChildNode.keys();
                int j=0;
                duration= new ArrayList<>();
                barEntries= new ArrayList<>();
                while(iterator.hasNext()){
                    String key = (String)iterator.next();
                    String issue = jsonChildNode.optString(key) ;
                    Float val=parseFloat(issue);
                    duration.add(key);
                    barEntries.add(new BarEntry(val,j));
                }
                j++;

                barDataSet= new BarDataSet(barEntries,"Qty");
                barDataSet.setColors(ColorTemplate.COLORFUL_COLORS);
                barData= new BarData(duration,barDataSet);

                barChart.setData(barData);
                barChart.animateY(3000);

输出就像下面一样 enter image description here

像这样循环移动j ++，

std::string func1();

int main()
{
  try
  {
    std::string const prop = func1();
    std::cout << prop << std::endl;
  }
  catch (std::exception const& e)
  {
    // Error handling ...
  }
}
