Bug in line chart yAxis when range are less than 1

[rolyanos]

Hello, maybe I doing something wrong, but I am think that there are small bug in y-axis.

here is the code:

override func viewDidLoad() {
    super.viewDidLoad()
    
    let data = generateLineData()
    testLineChartView.data = data
    
}

func generateLineData() -> LineChartData {
    let data: LineChartData = LineChartData()
    
    
    var entries: [ChartDataEntry] = []
    
    var dataArr: [Double] = []
    dataArr.append(0.1)
    dataArr.append(0.001)
    dataArr.append(0.8)
    dataArr.append(0.02)
    dataArr.append(1)
    
    
    for index in 0..<5 {
        entries.append(ChartDataEntry(x: Double(index)+0.5,  y: Double(dataArr[index]) ) )
    }
    
    let set: LineChartDataSet = LineChartDataSet(values: entries, label: "Label")
    set.setCircleColor(UIColor.blue)
    set.lineWidth = 1
    set.circleRadius = 5
    set.drawCircleHoleEnabled = false
    set.valueTextColor = UIColor.blue
    set.valueFont = UIFont(name: "Verdana", size: 12.0)!
    set.drawFilledEnabled = true
    set.mode = Charts.LineChartDataSet.Mode.linear
    set.axisDependency = Charts.YAxis.AxisDependency.left
    
    data.addDataSet(set)
    
    return data
}

What's the issue? seems totally fine to me.

@liuxuan30,there are no 0 number before "," symbol.

Needs 0,1 but there are ,1

check out valueFormatter

@thierryH91200, why? there are no needs of customization, just fix a bug with wrong numbers that less than 1. There are wrong numbers in yAxis,xAxis and in value label.

[thierryH91200]

no it's correct
x = 0.5, 1.5, 2.5 etc...
y = 0.1,0.001, 0.8, 0.02,1
format the values

Yep, it works with formatter, thanks. Strange, that it is not show 0 before "," by default.
