Example 1 - 7 -Output Screens

Example 7 - Line-Chart_3_Final4_Swift4 - This example work fine with swift 4

Following line/code is not available after 4.0 versions (i.e 4.2, 5.0 swift verions)

    chartViewOutlet.xAxis.valueFormatter = IndexAxisValueFormatter(value: months)

Solutions: - You need to add following code in order to show values on X- Axis

    let customFormater = CustomFormatter()
    customFormater.labels =  months
    chartViewOutlet.xAxis.valueFormatter = customFormater

and write seperate class like below,

final class CustomFormatter: IAxisValueFormatter{
    var labels: [String] = []
    func stringForValue(_ value: Double, axis: AxisBase?) -> String {
    
        let count = self.labels.count
    
        guard let axis = axis, count > 0 else {
            return ""
        }
    
        let factor = axis.axisMaximum / Double(count)
    
        let index = Int((value / factor).rounded())
    
        if index >= 0 && index < count {
            return self.labels[index]
        }
    
        return ""
    }
 }
