little issue with chart custoemView size & chart data

[MahmoudAbunaji]

i have two issues the first one is :

The pieChart is added as a subview in the viewController and it take a touch Gesture of whole the viewController that is mean if there a button below chart i cannot press that button , So how to change the size of the view that contain the pieChart ?

The second issue is i want to delete the values inside the circle [0,100] i want blank circle how can i do that ?

• i'm working in swift 3

This is my code :

func updateChartData(Points: String) {

    let chart = PieChartView(frame: self.view.frame)
    // 2. generate chart data entries
    
    
    self.pieChartView.legend.enabled = false
    self.pieChartView.circleBox.size 

    
    
    var entries = [PieChartDataEntry]()
    for (index, value) in Totals.enumerated() {
        let entry = PieChartDataEntry()
        entry.y = value
        entry.label = ""//Transactions[index]
        entries.append(entry)
    }
    
    // 3. chart setup
    let set = PieChartDataSet( values: entries, label: "")
    // this is custom extension method. Download the code for more details.
    var colors: [UIColor] = []
    
    for i in 0..<entries.count {
        //            let red = Double(arc4random_uniform(256))
        //            let green = Double(arc4random_uniform(256))
        //            let blue = Double(arc4random_uniform(256))
        //            let color = UIColor(red: CGFloat(red/255), green: CGFloat(green/255), blue: CGFloat(blue/255), alpha: 1)
        
        
        var color = UIColor.white
        
        if(i == 0)
        {
            let red = Double(5)
            let green = Double(113)
            let blue = Double(176)
            color = UIColor(red: CGFloat(red/255), green: CGFloat(green/255), blue: CGFloat(blue/255), alpha: 1)
        }
        else if(i == 1)
        {
            let red = Double(244)
            let green = Double(165)
            let blue = Double(130)
            color = UIColor(red: CGFloat(red/255), green: CGFloat(green/255), blue: CGFloat(blue/255), alpha: 1)

        }
        else if(i == 2)
        {
            let red = Double(202)
            let green = Double(0)
            let blue = Double(32)
            color = UIColor(red: CGFloat(red/255), green: CGFloat(green/255), blue: CGFloat(blue/255), alpha: 1)

        }

        colors.append(color)

    }
    
   // pieChartView.getLegend().setEnabled(false);
   
    pieChartView.animate(xAxisDuration: 2.0, yAxisDuration: 2.0)
    set.colors = colors
    let data = PieChartData(dataSet: set)
    chart.data = data
    chart.noDataText = NSLocalizedString("No data available", comment: "No Data")
    // user interaction
    chart.isUserInteractionEnabled = true
    
    let d = Description()
    d.text = ""
    
    chart.chartDescription = d
    chart.legend.enabled = false
    chart.centerText =  Points + NSLocalizedString(" \n POINTS", comment: "Points")
    chart.holeRadiusPercent = 0.5
    chart.transparentCircleColor = UIColor.clear
    chart.entryLabelColor = UIColor.white

    self.view.addSubview(chart) 
    
}

1. This is UIKit topic, not this library. Take a look at view.frame
2. dataSet.drawValuesEnabled = false
