CandleStick fill colors not showing

[Vaestro]

I am trying to present financial data in a CandleStick chart with the increasing fill color being green and the decreasing fill color being red. However the resulting chart ends up looking like this: https://s3.amazonaws.com/pearlventures/Screen+Shot+2017-08-21+at+6.37.24+PM.png

And here is the code concerning the chart:

override func viewDidLoad() {
    super.viewDidLoad()
    lineChartView = CandleStickChartView()
    let xAxis: XAxis? = lineChartView?.xAxis
    xAxis?.drawAxisLineEnabled = false
    xAxis?.drawGridLinesEnabled = false
    lineChartView?.leftAxis.enabled = false
    lineChartView?.rightAxis.enabled = false
    lineChartView?.legend.enabled = false
    lineChartView?.backgroundColor = .black
    lineChartView?.autoScaleMinMaxEnabled = true
    lineChartView?.noDataText = "No data"
    lineChartView?.animate(xAxisDuration: 2.0, yAxisDuration: 2.0, easingOption: .easeInBounce)
    lineChartView?.delegate = self
    lineChartView?.pinchZoomEnabled = false
  
    contentView.addSubview(lineChartView!)
    lineChartView?.snp.makeConstraints { (make) in
      make.top.equalTo(priceChangeLabel.snp.bottom)
      make.right.left.equalToSuperview()
      make.height.equalTo(200)
    }
}

func updateLineGraph() {
   var candleChartEntry = [CandleChartDataEntry]()
   for histo in histoArray {
     let histoValue = CandleChartDataEntry.init(x: histo.timestamp, shadowH: histo.high, shadowL: histo.low, open: histo.open, close: histo.close)
     candleChartEntry.append(histoValue)
   }
   let candle1 = CandleChartDataSet.init(values: candleChartEntry, label: "Candle")
   candle1.axisDependency = .left
   candle1.setColor(UIColor(white: 80 / 255.0, alpha: 1.0))
   candle1.drawIconsEnabled = false
   candle1.shadowColor = NSUIColor.darkGray
   candle1.shadowWidth = 1.5
   candle1.decreasingColor = NSUIColor.red
   candle1.decreasingFilled = true
   candle1.increasingColor = NSUIColor(red: 122 / 255.0, green: 242 / 255.0, blue: 84 / 255.0, alpha: 1.0)
   candle1.increasingFilled = false
   candle1.showCandleBar = true
   candle1.neutralColor = NSUIColor.blue
   candle1.drawValuesEnabled = false
   
   
   let candleData = CandleChartData()
   candleData.addDataSet(candle1)
   lineChartView?.data = candleData
 }

Have you checked ChartsDemo?

[Vaestro]

Yes @liuxuan30 I followed everything in the CandleStickChartViewController.m file

Can you at least draw the same candles like ChartsDemo? It's really not easy to know what happened with your code.

Just figured out the issue was because my x values were too big. I was trying to use timestamps as my x values and when I changed the x values to indexes of the array, the candles started to show properly.

Just ran into this same problem 😂
