mpandroidchart数据复制

Question

我在Fragment内有一个LineChart，并且包括一个微调框，用于按周/月/年过滤数据。 Fragment的OnCreateView会将其初始化为显示每周数据，但是当我选择微调器以按月或年份进行设置时，该数据将添加到先前设置的“每周”数据之上，而不是被清除。

这是我的OnCreateView方法：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_corporate_chart, container, false);
    corporateChart = view.findViewById(R.id.corporateChart);
    cChart.getAxisLeft().setAxisMaximum(150f);
    cChart.getAxisLeft().setAxisMinimum(0f);
    spinnerTime = view.findViewById(R.id.spinnerTime);
    spinnerMonth = view.findViewById(R.id.spinnerMonth);
    spinnerYear= view.findViewById(R.id.spinnerYear);

    months.add("JANUARY");
    months.add("FEBRUARY");
    months.add("MARCH");
    months.add("APRIL");
    months.add("MAY");
    months.add("JUNE");
    months.add("JULY");
    months.add("AUGUST");
    months.add("SEPTEMBER");
    months.add("OCTOBER");
    months.add("NOVEMBER");
    months.add("DECEMBER");

    time.add("WEEK");
    time.add("MONTH");
    time.add("YEAR");

    Calendar start = Calendar.getInstance();
    start.set(Calendar.YEAR, 2000);
    start.setTime(start.getTime());

    Calendar end = Calendar.getInstance();
    int yearnow = Calendar.getInstance().get(Calendar.YEAR);
    end.set(Calendar.YEAR, yearnow);
    end.setTime(end.getTime());

    while(start.before(end) || start.equals(end)){
        SimpleDateFormat year = new SimpleDateFormat("yyyy");
        Log.i("INFO", "START YEAR: " + start);
        Log.i("INFO", "START YEAR: " + end);
        years.add(year.format(start.getTime()));
        start.add(Calendar.YEAR, 1);
    }
    Collections.reverse(years);

    monthAdapter = new ArrayAdapter<>(getActivity(), R.layout.custom_spinner_left, months);
    yearAdapter = new ArrayAdapter<>(getActivity(), R.layout.custom_spinner_left, years);
    timeAdapter = new ArrayAdapter<>(getActivity(), R.layout.custom_spinner_left, time);

    spinnerMonth.setAdapter(monthAdapter);
    spinnerMonth.setPrompt("Select Month");

    spinnerYear.setAdapter(yearAdapter);
    spinnerYear.setPrompt("Select Year");

    spinnerTime.setAdapter(timeAdapter);
    spinnerTime.setPrompt("Select Time Range");

    setData("WEEK");


    spinnerTime.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            resetChart();
            selectedTime = parent.getItemAtPosition(position).toString();
            setData(selectedTime);
        }
        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

    return view;

}

这是我的setData（）方法

private void setData(String selectedTime)
{
    if(selectedTime.equals("WEEK"))
    {
        chartModel = createCChartFunction.setupWeekData(realm, corporateChart);
    }
    else if(selectedTime.equals("MONTH"))
    {
        chartModel = createCChartFunction.setupMonthData(realm, corporateChart);
    }
    else if(selectedTime.equals("YEAR"))
    {
        chartModel = createCChartFunction.setupYearData(realm, corporateChart);
    }

    ArrayList<Entry> e1 = new ArrayList<Entry>();
    final ArrayList<String> e2 = new ArrayList<>();

    for (int i = 0; i < chartModel.size(); i++) // Y Axis
    {
        e1.add(new Entry(i, chartModel.get(i).getyValueCount()));
    }

    for (int j = 0; j < chartModel.size() ; j++) // X Axis
    {
        e2.add(chartModel.get(j).getxValueDate());
    }

    LineDataSet AS = new LineDataSet(e1, "Corporate Accounts");
    AS.setLineWidth(2.5f);
    AS.setCircleRadius(4.5f);
    AS.setHighLightColor(Color.rgb(244, 117, 117));
    AS.setDrawValues(false);

    approvedSet = new ArrayList<ILineDataSet>();
    approvedSet.add(AS);
    approvedCorporate = new LineData(approvedSet);

    XAxis xAxis = corporateChart.getXAxis();
    xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
    xAxis.setDrawGridLines(false);
    xAxis.setGranularityEnabled(true);

    YAxis yAxisRight = corporateChart.getAxisRight();
    yAxisRight.setEnabled(false);

    YAxis yAxisLeft = corporateChart.getAxisLeft();
    yAxisLeft.setDrawGridLines(true);

    xAxis.setValueFormatter(new IAxisValueFormatter() {
        @Override
        public String getFormattedValue(float value, AxisBase axis) {
            return e2.get((int) value);
        }
    });

    IMarker marker = new chartMarker(getActivity(), R.layout.custom_chart_marker);
    corporateChart.setMarker(marker);

    cChart.setVisibleYRangeMaximum(10, YAxis.AxisDependency.LEFT);
    AS.notifyDataSetChanged();
    cChart.notifyDataSetChanged();
    cChart.setData(approvedCorporate);
    cChart.invalidate();
}

private void resetChart() {
    approvedSet.clear();
    approvedCorporate.notifyDataChanged();
    cChart.clearValues();
    cChart.notifyDataSetChanged();
    cChart.clear();
    cChart.invalidate();
}
