Custom marker android MP Chart

Question

I have to create a chart view like this with custom marker a dashed line which is draggable over the graph and it shows the points where the marker is left over. I have done the graph view with Mp chart android. How to add this draggable marker over the graph?

here is my graph view implementation.Graph is coming but no markers are showing

   AndroidView(
            factory = { LineChart(it) },
            update = { lineChart ->
                val marker = MarkerView(lineChart.context, R.layout.custom_marker)

                val dataSetList = chartData.map { dataSet ->
                    val entries = dataSet.pointsY.mapIndexed { index, yValue ->
                        Entry(convertTimeToFloat(dataSet.pointsX[index], "HH:mm"), yValue)
                    }
                    LineDataSet(entries, dataSet.legend).apply {
                        color = dataSet.lineColor
                        axisDependency = YAxis.AxisDependency.LEFT
                        cubicIntensity = 1f
                        this.lineWidth = lineWidthPx
                        valueTextColor = valuesColor.toArgb()
                        this.valueTextSize = valueTextSize.value

                    }
                }
