ios - Gráfico de vaina de coca no aparece(Swift4)

charts cocoapods

Question

Mi gráfico no muestra ninguna barra utilizando este gráfico de barras. He importado con éxito las tablas de la vaina de cacao. Actualmente no hay errores de tiempo de ejecución. Lo único que se muestra en el gráfico es la etiqueta de descripción.

    import UIKit
import Charts
class ViewController: UIViewController {


@IBOutlet var lineChartVIew: BarChartView!
var days: [String]!


override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    days = ["Monday","Tuesday","life"]
    let task = [1.0,4.0,3.0]
    setChart(dataPoints: days, values: task)
}

func setChart(dataPoints : [String], values : [Double]){
    lineChartVIew.noDataText = "Nothining to display"

    var dataEntries : [BarChartDataEntry] = []
    var counter = 0.0

    for i in 0..<dataPoints.count {
        counter += 1
        let dataEntery = BarChartDataEntry(x: values[i], y: counter)
        dataEntries.append(dataEntery)
    }

    let ChartDataSet = BarChartDataSet(values: dataEntries, label: "Time")
    let chartData = BarChartData()
    lineChartVIew.data = chartData
    ChartDataSet.colors = ChartColorTemplates.colorful()

    lineChartVIew.animate(xAxisDuration: 2.0, yAxisDuration: 2.0)
}}

Prueba este que está funcionando (Código Swift 4).

import UIKit
import Charts

class RootViewController: UIViewController {

@IBOutlet weak var lineChartView: BarChartView!

var days: [String]!

    override func viewDidLoad() {
         super.viewDidLoad()

         days = ["Monday","Tuesday","Wednesday","Thursday"]
         let task = [1.0,4.0,3.0,5.0]
         setChart(dataPoints: days, values: task)     
    }

    func setChart(dataPoints : [String], values : [Double]){

       lineChartView.noDataText = "Nothining to display"
       var dataEntries : [BarChartDataEntry] = []
       var counter = 0.0

       for i in 0..<dataPoints.count {
            counter += 1
            let dataEntery = BarChartDataEntry(x: counter, y:values[i], data: days as AnyObject)
            dataEntries.append(dataEntery)
       }

       let ChartDataSet = BarChartDataSet(values: dataEntries, label: "Time")
       let chartData = BarChartData()
       chartData.addDataSet(ChartDataSet)
       lineChartView.data = chartData
       ChartDataSet.colors = ChartColorTemplates.joyful()
       lineChartView.animate(xAxisDuration: 2.0, yAxisDuration: 2.0)

   }
}

La salida es:

Modificar gráfico ocultar y mostrar ejes y etiquetas

lineChartView.leftAxis.drawLabelsEnabled = false // Hide Left Axis Label
lineChartView.rightAxis.drawLabelsEnabled = false // Hide Right Axis Label
lineChartView.xAxis.drawLabelsEnabled = false // Hide Top Axis Label

lineChartView.leftAxis.enabled = false // Hide Left Axis Lines
lineChartView.rightAxis.enabled = false // Hide Right Axis Lines      
lineChartView.xAxis.enabled = false // Hide Right Axis Lines

lineChartView.legend.enabled = false //Hide Legend of Chart

lineChartView.chartDescription?.text = "" // Hide or Change Chart Description text
