Bar chart data entry

[ReFiRnE]

This is my current chart. I already have some custom NumberFormattor on it. But the display of values which I want active not quite what I need. Currently it's just a value which I passed to BarChartDataEntry. I wonder if I could send string there for value to display? I am looking for something similar to stringForValue. I use stringForValue where I return names for xAxis. Or if anyone have idea how I could implement formatter which is checking if x > 10.000 then display it as 10.0'(10k).

You can close case, I think I found how I could do it. Firstly I delegate IValueFormatter in ViewController. Then when I initialize BarChar tDataSet, I do valueFormatter = self. After that I can use
stringForValue(_ value: Double, entry: ChartDataEntry, dataSetIndex: Int, viewPortHandler: ViewPortHandler?) -> String
Thanks for awesome library!
