remove zero line from ios charts - swift

Question

I've created a simple small chart using (https://github.com/danielgindi/Charts), where i'm trying to remove everything beside the line itself, but i can't seem to remove the bottom zero axis. i've looked through the documentation, but cannot seem to remove it?
chart
class CellChartView: UIView {
var lineChart: LineChartView!
override init(frame: CGRect) {
super.init(frame: frame)
self.lineChart = LineChartView()
lineChart.backgroundColor = Color.lightTheme.value
lineChart.translatesAutoresizingMaskIntoConstraints = false
self.lineChart.chartDescription?.text = ""
self.lineChart.isUserInteractionEnabled = false
self.lineChart.legend.enabled = false
self.lineChart.minOffset = 0
self.lineChart.drawBordersEnabled = false
self.lineChart.drawGridBackgroundEnabled = false
self.lineChart.autoScaleMinMaxEnabled = true
self.lineChart.rightAxis.enabled = false
self.lineChart.leftAxis.enabled = false
self.lineChart.leftAxis.drawAxisLineEnabled = false
self.lineChart.leftAxis.axisLineColor = UIColor.green
self.lineChart.xAxis.drawLabelsEnabled = false
self.lineChart.xAxis.drawGridLinesEnabled = false
self.lineChart.xAxis.labelPosition = .bottom
self.lineChart.xAxis.drawLimitLinesBehindDataEnabled = false
self.lineChart.xAxis.enabled = false
self.lineChart.xAxis.axisLineColor = UIColor.clear
self.addSubview(self.lineChart)
lineChart.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
lineChart.topAnchor.constraint(equalTo: self.topAnchor, constant: -1).isActive = true
lineChart.widthAnchor.constraint(equalTo: self.widthAnchor).isActive = true
lineChart.heightAnchor.constraint(equalTo: self.heightAnchor).isActive = true
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setChartData(values: [Double], dates: [String]) {
var yValues : [ChartDataEntry] = [ChartDataEntry]()
for i in 0 ..< dates.count {
yValues.append(ChartDataEntry(x: Double(i + 1), y: values[i]))
}
let data = LineChartData()
let ds = LineChartDataSet(values: yValues, label: "Date")
ds.drawCirclesEnabled = false
ds.lineWidth = 1
ds.drawValuesEnabled = false
if (values.first ?? 0.0 > values.last ?? 0.0) {
ds.setColor(Color.redColor.value)
} else {
ds.setColor(Color.greenColor.value)
}
data.addDataSet(ds)
data.setDrawValues(false)
self.lineChart.data = data
}
}

Answer 1

If you just want to hide the xAxis, then I see two ways:
You could disable the xAxis xAxis.enabled = false
Or set the xAxis line color to transparent xAxis.axisLineColor = UIColor.clear

Answer 2

If you want to hide the horizontal and vertical lines being drawn through the center when you have disabled all grid lines and just want an X-Axis line as shown above in your drawing
lineChartDataSet.highlightColor = NSUIColor.clear
myLineChartView.xAxis.drawAxisLineEnabled = true
myLineChartView.xAxis.drawGridLinesEnabled = false
myLineChartView.xAxis.drawLabelsEnabled = false
myLineChartView.leftAxisAxis.drawAxisLineEnabled = false
This will just hide the horizontal and vertical lines while giving you the freedom to draw a line through X-Axis or Y-Axis.

Answer 3

If you just want to hide background gridlines
Just do
self.chartView?.leftAxis.drawGridLinesEnabled = false
self.charView?.xAxis.drawGridLinesEnabled = false
It will remove background grids for both axis. like that
