Swift 3 Line Chart Get Index

So Im making a graph using the Beautiful Charts Api. Im doing it in SWIFT 3. I got the graph working but now Im trying to get the selected value index, I have tried many things but they have not work. Heres my latest attempt at it.

func chartValueSelected(_ chartView: ChartViewBase, entry: 
     ChartDataEntry, highlight: Highlight) {

        if let dataSet = chartView.data?.dataSets[ highlight.dataSetIndex] {

            let Index: Int = dataSet.entryIndex( entry: entry)
            print( "Selected index: \( Index)")
        }
    }

Solution

  • You can use entry.x to retrieve the x value, or isn’t that the same as the index?

    print(“/(entry.x)”)
