How to show double vale with string in y-axis

[EndLess728]

• I've read, understood, and done my best to follow the *CONTRIBUTING guidelines.

What did you do?

ℹ NSformatter onlu accespts integer/double values but not string here is my code which i want to modify to show like i want .
for i in 0..<PayoutChart.count {

let value = ChartDataEntry(x: Double(i), y: PayoutChart[i])
lineChartEntry.append(value)
}
// here we add it to the data set

Note :- I am doing it for line chart in ios charts

let line1 = LineChartDataSet(values: lineChartEntry, label: "Payouts") //Here we convert lineChartEntry to a LineChartDataSet
line1.mode = .cubicBezier

ℹ I want to show the values on y axis like 1 min, 2 min , 3 min and so on ..

What happened instead?

ℹ it is showing the values like 1,2,3 and i want the string "min" as a suffix in y-axis values

I've managed to solve this by creating a custom axis formatter and implementing the required stringForValue function.

final class CustomAxisValueFormatter: IAxisValueFormatter {
    ....
    func stringForValue(_ value: Double, axis: AxisBase?) -> String {
        let yVal = Int(value)
        return "\(yVal) min"
   }
}

This is just an example using integer values on the axis. Will be slightly different if you need double values.

Don't forget to set leftAxis.valueFormatter on your chart to your custom formatter
