MPAndroidChart Xaxis. Does not call ValueFormatter for each points

I have spend a lot of time but can not find answer . I have a line graphics from 40 to 120 points. Each of the point has time. I wanted to show on Xaxis only points which have 0:00 or 12:00 time.

combinedChart.setData(prepareHistoryHour(photo_data));         combinedChart.fitScreen();         combinedChart.getXAxis().setAxisMinimum(0);         combinedChart.getXAxis().setGranularity(1);         combinedChart.getXAxis().setGranularityEnabled(true);         combinedChart.getXAxis().setLabelCount(72);        combinedChart.getXAxis().setTextSize(14f);         combinedChart.setVisibleXRangeMaximum(72);         combinedChart.setMaxVisibleValueCount(700);         combinedChart.getLineData().setDrawValues(true);         combinedChart.getXAxis().setValueFormatter(new ValueFormatter() {             @Override             public String getFormattedValue(float value) {                   Log.d("WHS xaxis", String.valueOf(value));                 long time=dc_forecastHourList.get((int)value).getDT_withOffset();                     String s=new SimpleDateFormat("HH").format(new Date(time*1000L));                 if (Integer.parseInt(s) ==0){                     return new SimpleDateFormat("MMdd").format(new Date(time*1000L));                 }                     if (Integer.parseInt(s) %12==0){                         return new SimpleDateFormat("HH").format(new Date(time*1000L))+":00";                     }               return  "";             }           });    

But ValueFormatter is called not for all points. It was call with skip different intervals..

Logs: for example

D/WHS xaxis: 24.0  D/WHS xaxis: 27.0  D/WHS xaxis: 30.0  D/WHS xaxis: 33.0  D/WHS xaxis: 36.0  

As a result I cannot show correct values on Xaxis. Thank you for help!
