SwiftChart has no member chart


I am using the SwiftCharts library found here.

I have the following code:

class ChartTestViewController: UIViewController {

@IBOutlet weak var chartView: UIView!

override func viewDidLoad() {
    super.viewDidLoad()


    let xaxis = ["monday", "tuesday", "wednesday", "thursday", "friday"]
    let yaxis = [1, 2, 3, 4, 5]

    let letdoublearray = yaxis.map { Double($0) }

    let tuples = zip(xaxis, letdoublearray).map { ($0, $1) }


    let chartConfig = BarsChartConfig(
        valsAxisConfig: ChartAxisConfig(from: 0, to: 8, by: 2)
    )

    let frame = CGRect(x: 0, y: 70, width: 300, height: 500)

    let chart = BarsChart(
        frame: frame,
        chartConfig: chartConfig,
        xTitle: "X axis",
        yTitle: "Y axis",
        bars: tuples,
        color: UIColor.red,
        barWidth: 20
    )

    self.chart = chart // error here
    self.chartView = chart.view

I am getting an error at the self.chart = chart line saying chart is not a member of the class. I already have chart defined so I am not sure where else I need to create another chart variable.


Solution

  • Your view controller does not have a chart property. Simply add one.

    class ChartTestViewController: UIViewController {
        var chart: BarsChart!
    
        @IBOutlet weak var chartView: UIView!
    
        override func viewDidLoad() {
            super.viewDidLoad()
    
            // lots of code here
    
            self.chart = chart
        }
