**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 ""

        }

     }
