MPAndroidChart，Y轴比例得到更新，但线未更新 [英] MPAndroidChart, Y-Axis Scale gets updated but lines are not

问题描述

我正在使用 MPAndroidChart .我有以下活动- StockDetail.Java

I am using MPAndroidChart. I have the following Activity - StockDetail.Java

公共类StockDetail扩展了AppCompatActivity { ArrayList historyData = null;

public class StockDetail extends AppCompatActivity{ ArrayList historicalData=null;

@Override
public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    SharedPreferences prefs=getApplicationContext().getSharedPreferences("arrayList",Context.MODE_PRIVATE);

    try {
        historicalData = (ArrayList<HistoricalData>) ObjectSerializer.deserialize(prefs.getString(
                Utils.ARRAY_LIST, ObjectSerializer.serialize(new ArrayList<HistoricalData>())));
    } catch (IOException e) {
        e.printStackTrace();
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    setContentView(R.layout.stock_detail);

    LineChart lineChart=(LineChart) findViewById(R.id.lineChart);


    List<Entry> datas=new ArrayList<>();
    ArrayList<Float> floats=getDateInFloatValues(historicalData);
    HistoricalData hData;
    for (int i=0; i<historicalData.size(); i++) {
        hData=historicalData.get(i);
        datas.add(new Entry(floats.get(i),Float.parseFloat(hData.getHigh())));
    }
    LineDataSet lineDataSet=new LineDataSet(datas,"LineData");
    lineDataSet.setColor(R.color.material_red_700);
    LineData lineData=new LineData(lineDataSet);
    lineChart.setData(lineData);
    lineChart.invalidate();
}

}
