Using 3rd party "charts",the response values as double.How it make to integer format? - ios

Question

Using third party "charts".the input format of values are Double and response also in double.For example, my input is a=12,b=13,c=20,d=25 when it comes in graph showing like a=12.0,b=13.0,c=20.0,d=25.0
here is my code
func updateChartData() {
let skipped = 12
let correct = 13
let wrong = 20
let timedOut = 25
let track = ["Skipped", "Right", "Wrong", "Not Attended"]
let money = [skipped, correct, wrong, timedOut]
var entries = [PieChartDataEntry]()
for (index, value) in money.enumerated() {
let entry = PieChartDataEntry()
entry.y = Double(value)
entry.label = track[index]
entries.append( entry)
}
// 3. chart setup
let set = PieChartDataSet( values: entries, label: "Pie Chart")
// this is custom extension method. Download the code for more details.
var colors: [UIColor] = []
for _ in 0..<money.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)
colors.append(color)
}
set.colors = colors
let data = PieChartData(dataSet: set)
viewPieCharts.data = data
viewPieCharts.noDataText = "No data available"
// user interaction
viewPieCharts.isUserInteractionEnabled = true
let d = Description()
d.text = "iOSCharts.io"
viewPieCharts.chartDescription = d
viewPieCharts.centerText = "Pie Chart"
viewPieCharts.holeRadiusPercent = 0.5
viewPieCharts.transparentCircleColor = UIColor.clear
}
I want the values without decimal point.

Answer 1

Just insert this code
let format = NumberFormatter()
format.numberStyle = .none
let formatter = DefaultValueFormatter(formatter: format)
data.setValueFormatter(formatter)
after
let data = PieChartData(dataSet: set)

Answer 2

Override IValueFormatter and set it to your PieChartData instance
class MyValueFormatter : IValueFormatter {
func stringForValue(_ value: Double,
entry: ChartDataEntry,
dataSetIndex: Int,
viewPortHandler: ViewPortHandler?) -> String {
return String(format: "%.0f", value)
}
}
data.setValueFormatter(MyValueFormatter())
