Change color of Bar chart data label

[Zwaaan]

When I write this code:

let set = BarChartDataSet(values: entries, label: "Test")
set.colors = [UIColor.green]
set.valueTextColor = UIColor.white
set.valueFormatter = IntegerValueFormatter()
let data = BarChartData(dataSet: set)
chart.data = data

The small box under the graph is turned green, but the text that says "Test" is still a black color, I've tried to change the color and font in many ways with no success.

So how to I change the bar chart data label color/font?

    /// List representing all colors that are used for drawing the actual values for this DataSet
    open var valueColors = [NSUIColor]()

    /// the font for the value-text labels
    var valueFont: NSUIFont { get set }

how valueColors are being used:

    /// - returns: The color at the specified index that is used for drawing the values inside the chart. Uses modulus internally.
    open func valueTextColorAt(_ index: Int) -> NSUIColor
    {
        var index = index
        if index < 0
        {
            index = 0
        }
        return valueColors[index % valueColors.count]
    }

please check ChartsDemo.. it's all there, and drawValues()

@liuxuan30 This changes the color/font in the chart, but the Label under the chart is not changed and remains black and in default font.
