Usage

  1. Add your Data to the chart :

import UIKit
import ChartProgressBar

class ViewController: UIViewController, ChartProgressBarDelegate {

@IBOutlet weak var chart: ChartProgressBar!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.

        var data: [BarData] = []

        data.append(BarData.init(barTitle: "Jan", barValue: 1.4, pinText: "1.4 €"))
        data.append(BarData.init(barTitle: "Feb", barValue: 10, pinText: "10 €"))
        data.append(BarData.init(barTitle: "Mar", barValue: 3.1, pinText: "3.1 €"))
        data.append(BarData.init(barTitle: "Apr", barValue: 4.8, pinText: "4.8 €"))
        data.append(BarData.init(barTitle: "May", barValue: 6.6, pinText: "6.6 €"))
        data.append(BarData.init(barTitle: "Jun", barValue: 7.4, pinText: "7.4 €"))
        data.append(BarData.init(barTitle: "Jul", barValue: 5.5, pinText: "5.5 €"))

        chart.data = data
        chart.barsCanBeClick = true
        chart.maxValue = 10.0
        chart.emptyColor = UIColor.clear
        chart.barWidth = 7
        chart.progressColor = UIColor.init(hexString: "99ffffff")
        chart.progressClickColor = UIColor.init(hexString: "F2912C")
        chart.pinBackgroundColor = UIColor.init(hexString: "E2335E")
        chart.pinTxtColor = UIColor.init(hexString: "ffffff")
        chart.barTitleColor = UIColor.init(hexString: "B6BDD5")
        chart.barTitleSelectedColor = UIColor.init(hexString: "FFFFFF")
        chart.pinMarginBottom = 15
        chart.pinWidth = 70
        chart.pinHeight = 29
        chart.pinTxtSize = 17
        chart.delegate = self
        chart.build()

        chart.disableBar(at: 3)

    let when = DispatchTime.now() + 6 // change 2 to desired number of seconds
        DispatchQueue.main.asyncAfter(deadline: when) {
            self.chart.enableBar(at: 3)
        }
    }   
  }

To Handle ChartProgressBarDelegate

  extension MainViewController: ChartProgressBarDelegate {
    func ChartProgressBar(_ chartProgressBar: ChartProgressBar, didSelectRowAt rowIndex: Int) {
        print(rowIndex)
    }
}

Useful methods

  1. chart.removeValues() : Remove values of all progress bars in the chart.

  2. chart.resetValues() : Set values to the chart ( it may used after removeBarValues()) .

  3. chart.removeClickedBar() : Unselect the clicked bar.

  4. isBarsEmpty() : Check if bars values are empty.

  5. chart.disableBar(at: Int) : Disable a bar progmatically.

  6. chart.enableBar(at: Int) : Enable a bar progmatically.

  7. clickBar(index: Int) : Click a bar progmatically.
