wish of those help You can download the project here https://github.com/PhilJay/MPAndroidChart/archive/master.zip Open the project, and in MPChartExample, you have the file DynamicalAddingActivity.java.
You need to create the chart: Add dataSet (your line(s)) with the values (please view the example in addDataSet() method in MPChartExample project). After you can do a CountTimerDown that add a new Entry, for the dataset.
code :
/** each 5 seconds **/
new CountDownTimer(5000, 1000) {

     public void onTick(long millisUntilFinished) {
     }

     public void onFinish() {
        double randomValue = 19.0 + (Math.random() * (21.0 - 19.0)); 
        int indexOfMyLine = 0;

        Entry newEntry = new Entry((float) randomValue, indexOfMyLine); 
     }

this will help This feature just became available, please check out the AxisValueFormatter interface.
It allows to dynamically adjust axis labels before drawing them which means you can write your own logic and decide what get's displayed and what not. Always bear in mind that performance is critical here as methods of this interface are invoked (potentially) thousands of times when drawing the chart. Especially avoid unnecessary memory allocations or expensive loops.

seems to work fine The problem is, you are setting the dataset to chart and then you are setting its X Range instead of setting X Range before setting the dataset to chart.
You can add either following code in else part at the end:
code :
horizontalBarChart.invalidate();
horizontalBarChart.refreshDrawableState();
horizontalBarChart.setVisibleXRangeMaximum(10);
horizontalBarChart.setVisibleXRangeMinimum(7);

I hope this helps you . creating a Dynamic xAxis label in MPAndroidChart library.
code :
 public ArrayList<String> getweakAreaCount() {

        ArrayList<String> label = new ArrayList<>();
        for (int i = 0; i < weakAreaList.size(); i++)
            label.add(weakAreaList.get(i).getTopicNm());
        return label;
    }

xAxis.setValueFormatter(new IndexAxisValueFormatter(getweakAreaCount));
