BarChar Position Label

[nija78]

It's possible to display the label of negative Value on the top of the bar instead of botom?

in BarChartRenderer.swift
open override func drawValues(context: CGContext)

 if dataSet.isDrawValuesEnabled
                        {
                            drawValue(
                                context: context,
                                value: formatter.stringForValue(
                                    val,
                                    entry: e,
                                    dataSetIndex: dataSetIndex,
                                    viewPortHandler: viewPortHandler),
                                xPos: x,
                                yPos: abs(val) >= 0.0  <-------------------- line modified val always >0
                                    ? (rect.origin.y + posOffset)
                                    : (rect.origin.y + rect.size.height + negOffset),
                                font: valueFont,
                                align: .center,
                                color: dataSet.valueTextColorAt(j),
                                rotationAngle: valueRotationAngle)
                        }
