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

"Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself" Since the dates on the x axis seem to be the problem, it would be especially helpful to see the code of MyAxisValueFormatter
