MPAndroid Chart not displaying any labels for xAxis , what is missing?

I'm implementing a feature for displaying Incomes/Expenses for properties & also provided Filter for 1 Month , 3 Months , 6 Months & 12 Months .

So, I have to display Months labels according to filter selected for example if 3 Month filter selected then need to display March , Feb & Jan but what currently these labels are not displayed.

Code is displayed for 3 months filter which has same issue.

Here is my code , please rectify any issue:

private void setChart() {

    ArrayList<BarEntry> incomeEntries = getIncomeEntries();
    ArrayList<BarEntry> expenseEntries = getExpenseEntries();

    BarDataSet set1, set2;

    set1 = new BarDataSet(incomeEntries, "Income");
    set1.setColor(Color.rgb(65, 168, 121));
    set1.setValueTextColor(Color.rgb(55, 70, 73));
    set1.setValueTextSize(10f);

    set2 = new BarDataSet(expenseEntries, "Expense");
    set2.setColors(Color.rgb(241, 107, 72));
    set2.setValueTextColor(Color.rgb(55, 70, 73));
    set2.setValueTextSize(10f);

    ArrayList<IBarDataSet> dataSets = new ArrayList<>();
    dataSets.add(set1);
    dataSets.add(set2);

    BarData data = new BarData(dataSets);
    barChart.setData(data);


    barChart.getDescription().setEnabled(false);
    barChart.setDrawBarShadow(false);
    barChart.setDrawValueAboveBar(true);
    barChart.setMaxVisibleValueCount(10);
    barChart.setPinchZoom(false);
    barChart.setDrawGridBackground(false);
    barChart.animateY(1400, Easing.EaseInOutQuad);
    barChart.animateXY(3000, 3000);

    Legend l = barChart.getLegend();
    l.setWordWrapEnabled(true);
    l.setTextSize(14);
    l.setVerticalAlignment(Legend.LegendVerticalAlignment.TOP);
    l.setHorizontalAlignment(Legend.LegendHorizontalAlignment.CENTER);
    l.setOrientation(Legend.LegendOrientation.HORIZONTAL);
    l.setDrawInside(false);
    l.setForm(Legend.LegendForm.CIRCLE);


    XAxis xAxis = barChart.getXAxis();
    xAxis.setGranularity(1f);
    xAxis.setCenterAxisLabels(true);
    xAxis.setDrawGridLines(false);
    xAxis.setLabelRotationAngle(-45);
    xAxis.setPosition(XAxis.XAxisPosition.BOTTOM);
    xAxis.setAxisMaximum(data.getXMax() + 0.25f);
    ArrayList<String> formatter = getFormattter();
    barChart.getXAxis().setValueFormatter(new IndexAxisValueFormatter(formatter));
    barChart.getXAxis().setLabelCount(formatter.size(),true);

    YAxis leftAxis = barChart.getAxisLeft();
    leftAxis.removeAllLimitLines();
    leftAxis.setTypeface(Typeface.DEFAULT);
    leftAxis.setPosition(YAxis.YAxisLabelPosition.OUTSIDE_CHART);
    leftAxis.setTextColor(Color.BLACK);
    leftAxis.setDrawGridLines(false);
    leftAxis.setAxisMinValue(0f); // this replaces setStartAtZero(true
    barChart.getAxisRight().setEnabled(false);

    float maxValue = 0, minValue = 0;

    for (int i = 0; i < incomeEntries.size(); i++) {

        if (maxValue < incomeEntries.get(i).getY()) {
            maxValue = incomeEntries.get(i).getY();
        }

        if (maxValue < expenseEntries.get(i).getY()) {
            maxValue = expenseEntries.get(i).getY();
        }

    }

    maxValue = maxValue + 100;
    Log.e(TAG, "==================== MAX VALUE = " + maxValue);

    leftAxis.setAxisMaximum(maxValue);
    leftAxis.setAxisMinimum(minValue);

    leftAxis.setAxisMaxValue(maxValue);
    leftAxis.setStartAtZero(true);

    data.setValueFormatter(new LargeValueFormatter());

    //data
    float groupSpace = 0.25f;
    float barSpace = 0.05f; // x2 dataset
    float barWidth = 0.35f; // x2 dataset


    barChart.getBarData().setBarWidth(barWidth);
    barChart.getXAxis().setAxisMinValue(10f);
    barChart.groupBars(10, groupSpace, barSpace);
    barChart.invalidate();

}

private ArrayList<String> getFormattter() {

    Log.e(TAG, "GET FORMATTED VALUE");

    switch (chartType) {

        case AppConstants.CHART_TYPE_1_MONTH:
            monthFormatter();
            return oneMonthLabels;

        case AppConstants.CHART_TYPE_3_MONTH:
            threeMonthFormatter();
            return threeMonthLabels;

        case AppConstants.CHART_TYPE_6_MONTH:
            sixMonthFormatter();
            return sixMonthLabels;

        case AppConstants.CHART_TYPE_12_MONTH:
            yearFormatter();
            return yearLabels;
    }
    return null;
}

private void threeMonthFormatter() {

    Log.e(TAG, "threeMonthFormatter , label list size : " + threeMonthLabels.size());
    if (null != threeMonthLabels) {
        threeMonthLabels.clear();
    }

    Calendar calendar = Calendar.getInstance();
    String month = new SimpleDateFormat("MMM").format(calendar.getTime());
    threeMonthLabels.add(month);

    calendar.add(Calendar.MONTH, -1);
    month = new SimpleDateFormat("MMM").format(calendar.getTime());
    threeMonthLabels.add(month);

    calendar.add(Calendar.MONTH, -1);
    month = new SimpleDateFormat("MMM").format(calendar.getTime());
    threeMonthLabels.add(month);

    for (int i = 0; i < threeMonthLabels.size(); i++) {
        Log.e(TAG, "Label : " + threeMonthLabels.get(i));
    }
}

I have attached screen which is achieved as of now.As you can see as per three month Filter , it's displaying bars as per 3 months but there are no labels even monthFormatter create exactly 3 months labels.

Any help would be appreciated.
