specificPositions not working in the HorizontalBarChart

[jihoon4372]

I tried to use specificPositions in the HorizontalBarChart, but it does not work.
it works in the BarChart but it does not work in the HorizontalBarChart.

the code I used is

val hyAxis = hChart.axisLeft    
hyAxis.removeAllLimitLines()
hyAxis.axisLineColor = Color.TRANSPARENT
hyAxis.gridColor = Color.TRANSPARENT
hyAxis.textColor = Color.BLACK
if(range!=0f){
    hyAxis.axisMaximum = range * 5
}else{
    hyAxis.axisMaximum = wMaximum * 5
}
hyAxis.axisMinimum = 0f
hyAxis.setDrawGridLines(false)
hyAxis.isEnabled = true
hyAxis.isShowSpecificPositions = true
hyAxis.specificPositions = floatArrayOf(300000f)

Could someone tell me if i wrote the code something wrong, so then I'll fix my codes with great appreciation
