Multiple colors issue in stacked bar line charts swift3

[jiheneme]

Hi everyone,

I need to create a stacked bar chart with 3 dataSets like this :

But when I used this code :
********************** Begin ******************************
let chiffreAffaire = [3282.0, 4179.0]
let chiffreAffaireDetails1 = [788.0, 889.0]
let chiffreAffaireDetails2 = [300.0, 330.0]
let chiffreAffaireDetails3 = [2247.0, 1843.0]

    var yse1 = chiffreAffaireDetails1.enumerated().map { x, y in return BarChartDataEntry(x: Double(x), y: y) }
    var yse2 = chiffreAffaireDetails2.enumerated().map { x, y in return BarChartDataEntry(x: Double(x), y: y) }
    var yse3 = chiffreAffaireDetails3.enumerated().map { x, y in return BarChartDataEntry(x: Double(x), y: y) }
    var yse = chiffreAffaire.enumerated().map { x, y in return BarChartDataEntry(x: Double(x), y: y) }

    let data = BarChartData()
    let ds1 = BarChartDataSet(values: yse1, label: "")
    let ds2 = BarChartDataSet(values: yse2, label: "")
    let ds3 = BarChartDataSet(values: yse3, label: "")
    let ds4 = BarChartDataSet(values: yse, label: "")
    
    data.barWidth=0.6
    
    ds4.setColor (UIColor.detailsBtnGreen)
    ds4.valueFont=UIFont(name:"Avenir-Book" ,size:20.0)!
    data.addDataSet(ds4)
  
    ds2.setColor (UIColor.pistachioGreen)
    ds2.valueFont=UIFont(name:"Avenir-Book" ,size:20.0)!
    ds2.valueTextColor=UIColor.white
    data.addDataSet(ds2)
    
    ds1.setColor (UIColor.pinkBar)
    ds1.valueFont=UIFont(name:"Avenir-Book" ,size:20.0)!
    ds1.valueTextColor=UIColor.white
    data.addDataSet(ds1)
    
    ds3.setColor(UIColor.royalBlue)
    ds3.valueFont=UIFont(name:"Avenir-Book" ,size:20.0)!
    ds3.valueTextColor=UIColor.white
    data.addDataSet(ds3)

    self.barChartView.data = data

********************** End ******************************

I had this result :

The problem is that it takes only the first and the last dataSet colors !

Someone can help me please ?
Thanks in advance ( and sorry for my bad english ;-) )

Please check out ChartsDemo, there are full examples.. As far as I know from your picture, there should only be one data set with multiple entries.
