Can I show all the markers using iOS charts? - ios

Question

Can I show all the markers without clicking on a bar?
currently, I need to tap on any of the bar and it'll only show the one that is clicked. I'm trying to add a marker on each of the green bar and showing all without any bar being clicked. Is it possible?
Edit:
Below is my code changed from the github demo code
(PillMarker came from this)
import Charts
import UIKit
class BarChartViewController: DemoBaseViewController {
#IBOutlet var chartView: BarChartView!
#IBOutlet var sliderX: UISlider!
#IBOutlet var sliderY: UISlider!
#IBOutlet var sliderTextX: UITextField!
#IBOutlet var sliderTextY: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
self.options = [.animateY]
self.setup(barLineChartView: chartView)
chartView.delegate = self
chartView.drawBarShadowEnabled = false
chartView.drawValueAboveBarEnabled = false
chartView.maxVisibleCount = 60
chartView.dragEnabled = false
chartView.scaleXEnabled = false
chartView.scaleYEnabled = false
chartView.leftAxis.drawAxisLineEnabled = false
chartView.xAxis.drawGridLinesEnabled = false
chartView.legend.enabled = false
let xAxis = chartView.xAxis
xAxis.labelPosition = .bottom
xAxis.labelFont = .systemFont(ofSize: 10)
xAxis.labelTextColor = .green
xAxis.granularity = 1
xAxis.labelCount = 7
xAxis.valueFormatter = DayAxisValueFormatter(chart: chartView)
let leftAxis = chartView.leftAxis
leftAxis.labelFont = .systemFont(ofSize: 10)
leftAxis.labelTextColor = .red
leftAxis.labelCount = 8
leftAxis.labelPosition = .outsideChart
leftAxis.spaceTop = 0.15
leftAxis.axisMinimum = 0
let l = chartView.legend
l.horizontalAlignment = .left
l.verticalAlignment = .bottom
l.orientation = .horizontal
l.drawInside = false
l.form = .square
l.formSize = 9
l.font = UIFont(name: "HelveticaNeue-Light", size: 11)!
l.textColor = .blue
l.xEntrySpace = 4
//Marker
let marker = PillMarker(color: .white, font: UIFont.boldSystemFont(ofSize: 14), textColor: .black)
chartView.marker = marker
sliderX.value = 12
sliderY.value = 50
slidersValueChanged(nil)
}
override func updateChartData() {
if self.shouldHideData {
chartView.data = nil
return
}
self.setDataCount(1, range: UInt32(sliderY.value))
}
func setDataCount(_ count: Int, range: UInt32) {
let start = 1
let yVals = (start..<start+count+1).map { (i) -> BarChartDataEntry in
let mult = range + 1
let val = Double(arc4random_uniform(mult))
return BarChartDataEntry(x: Double(i), y: val)
}
var set1: BarChartDataSet! = nil
if let set = chartView.data?.first as? BarChartDataSet {
set1 = set
set1.replaceEntries(yVals)
chartView.data?.notifyDataChanged()
chartView.notifyDataSetChanged()
} else {
set1 = BarChartDataSet(entries: yVals, label: "The year 2017")
set1.colors = ChartColorTemplates.material()
set1.highlightColor = NSUIColor(red: 46/255.0, green: 204/255.0, blue: 113/255.0, alpha: 1.0)
set1.drawValuesEnabled = false
set1.drawIconsEnabled = true
let data = BarChartData(dataSet: set1)
data.setValueFont(UIFont(name: "HelveticaNeue-Light", size: 10)!)
data.barWidth = 0.3
chartView.data = data
}
}

Yes, You can show all marker on bar.
put marker code with bar drawing code.
