I'm using MPAndroidChart in my android application but the x-axis is wrong formatted and label are duplicated. Here my code

private fun lineChart(exams: List<Exam>) {

        val formatter: DateFormat = SimpleDateFormat("dd/MM/yyyy")



        val lineChart: LineChart = linechart

        lineChart.animateY(1000)

        val d = Description()

        d.text = "TEST"

        lineChart.description = d



        val yValues: ArrayList<Entry> = ArrayList()

        var count = 0

        for (exam in exams.sortedByDescending { exam -> exam.date }) {

            if (getString(R.string.scores_array_admitted) != exam.score)

                yValues.add(Entry(count++.toFloat(), exam.score.toFloat()))

        }



        val lineDataSet = LineDataSet(yValues, getString(R.string.linechart_score_label))

        val dataSet: ArrayList<ILineDataSet> = ArrayList()

        dataSet.add(lineDataSet)



        val lineData = LineData(dataSet)



        val xAxis: XAxis = lineChart.xAxis



        val values = ArrayList<String>()

        for (exam in exams.sortedByDescending { exam -> exam.date }) {

            if (getString(R.string.scores_array_admitted) != exam.score)

                values.add(formatter.format(exam.date))

        }



        val array = arrayOfNulls<String>(values.size)

        values.toArray(array)



        var aa = array!!





        xAxis.valueFormatter = MyAxisValueFormatter(aa)



        lineChart.data = lineData



    }

In debug I see that the value in the arrays are correct, 2 exams and in values array the label are the two date of the exam and they are exactly two, but when I run my application the result is this

In x axis I would have only two date
