    barChart.center = view.center
    view.addSubview(barChart)
    
    var entries = [BarChartDataEntry]()
    for x in 0..<10{
        entries.append(BarChartDataEntry(x: Double(x), y: Double(x)))
    }
    let set = BarChartDataSet(entries)
    set.colors = ChartColorTemplets.joyful() 
    let data = BarChartData(dataSet: set)
    barChart.data = data
    }

    var entries = [LineChartDataEntry]()
    for x in 0..<10{
        entries.append(LineChartDataEntry(x: Double(x), y: Double(x)))
    }
    let set = LineChartDataSet(entries)
    set.colors = ChartColorTemplets.material()

    lineChart.data = data
    }

    }  
    
    override func  viewDidLayoutSubviews(){
    super.viewDidLayoutSubviews()
    pieChart .frame = CGRect(x: 0, y: 0, width: self.view,frame.size.width , hieght: self.view,frame.size.width)
    pieChart .center = view.center
    view.addSubview(pieChart )
    
    var entries = [PieChartDataEntry]()
    for x in 0..<10{
        entries.append(PieChartDataEntry(x: Double(x), y: Double(x)))
    }
    let set = PieChartDataSet(entries)
    set.colors = ChartColorTemplets.colorful()
    let data = PieChartData(dataSet: set)
    pieChart .data = data
    }
}
