I use MPAndroidChart v3.0.2 now.
The problem is that lasst data('05일') is not showing...

This is the value while I get on Debug
xVals : 1일, 2일, 5일

and It is the source and the result screenshot.

I think the '5일' enter the 'red circle'... but I don't know the reason..

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

    if (ExRegList.length() == 0) {

        chart.clear();

        chart.setDescription(null);

        chart.setNoDataText("데이터가 존재하지 않습니다."); // There is no data.

        chart.invalidate();

    } else {

        ArrayList<Entry> entries = new ArrayList<Entry>();

        final String xVals = new String[ExRegList.length()];



        try {

            for (int i = 0; i < ExRegList.length(); i++) {

                JSONObject obj = ExRegList.getJSONObject(i);

                String date = obj.getString("REG_DT").split("-")[2] + "일";

                xVals[i] = date;

                int score = obj.getInt("ANSWER02");

                switch (score) {

                    case 1:

                        entries.add(new Entry(i,3f));//매우만족

                        break;

Instead of this:

bottomAxis.setLabelCount(entries.size());

Use this overloaded version:

bottomAxis.setLabelCount(entries.size(), true);

Second parameter, boolean force forces to have exact number of labels. Without it, sometimes the method doesn't work, like in your case. From source code you can see:

sets the number of label entries for the y-axis max = 25, min = 2,
default: 6, be aware that this number is not fixed (if force == false)
and can only be approximated.
