if I want to set the RadarLabel like this!
public override func renderAxisLabels(context context: CGContext)
{
if (!_xAxis.isEnabled || !_xAxis.isDrawLabelsEnabled)
{
return
}

    let labelFont = _xAxis.labelFont
    let labelTextColor = _xAxis.labelTextColor
    let labelRotationAngleRadians = _xAxis.labelRotationAngle * ChartUtils.Math.FDEG2RAD
    let drawLabelAnchor = CGPoint(x: 0.5, y: 0.0)

    let sliceangle = _chart.sliceAngle

    // calculate the factor that is needed for transforming the value to pixels
    let factor = _chart.factor

    let center = _chart.centerOffsets

    let modulus = _xAxis.axisLabelModulus
    for var i = 0, count = _xAxis.values.count; i < count; i += modulus
    {
        let label = _xAxis.values[i]

        if (label == nil)
        {
            continue
        }
        if (_xAxis.labelPosition == .Top)
        {

        }
        let angle = (sliceangle * CGFloat(i) + _chart.rotationAngle) % 360.0


        let p = ChartUtils.getPosition(center: center, dist: CGFloat(_chart.yRange) * factor + _xAxis.labelRotatedWidth / 2.0, angle: angle)
        if(angle == 270){
            drawLabel(context: context, label: label!, xIndex: i, x: p.x, y: p.y - _xAxis.labelRotatedHeight / 2.0 - 100, attributes: [NSFontAttributeName: UIFont.systemFontOfSize(14), NSForegroundColorAttributeName: UIColor.greenColor()], anchor: drawLabelAnchor, angleRadians: labelRotationAngleRadians)

// drawLabel(context: context, label: label!, xIndex: i, x: p.x, y: p.y - _xAxis.labelRotatedHeight / 2.0, attributes: [NSFontAttributeName: labelFont, NSForegroundColorAttributeName: labelTextColor], anchor: drawLabelAnchor, angleRadians: labelRotationAngleRadians)
}else{

            drawLabel(context: context, label: label!, xIndex: i, x: p.x, y: p.y - _xAxis.labelRotatedHeight / 2.0, attributes: [NSFontAttributeName: labelFont, NSForegroundColorAttributeName: labelTextColor], anchor: drawLabelAnchor, angleRadians: labelRotationAngleRadians)
        }


    }
}

the QUESTION is 👍
the labelRotatedHeight and the Label color is changed, but when the RadarView Rotating! the Label will be reDraw and the setting is Invalid.

so where is the method of the label redraw and how could i setting?
thank u very much!

it's in drawRect: either figure out a way to dynamicly change your setting or disable the redrawLabels if you detect it's rotating, or just disable the rotate

    public override func drawRect(rect: CGRect)
    {
        super.drawRect(rect)

        if (_dataNotSet)
        {
            return
        }

        let optionalContext = UIGraphicsGetCurrentContext()
        guard let context = optionalContext else { return }

        _xAxisRenderer?.renderAxisLabels(context: context)

I want when it Rotating and the color and position of the TOP Label be changed only. but there have some Automatic calculation bothers me ,

[liuxuan30]

I guess you have to write your own logic for what you want. If something bothers you, just override the method and take what you need.

thank u very much
