Changing chart data in IOS - ios

Question

So I am having trouble with some charting in Swift. I am using the following charting pod: https://github.com/aunnnn/RHLinePlot
I am using UIKit so I inserted a swiftUI view into my view controller. The charts work fine but whenever I change to a different timeline some data seems to be stuck from other timeperiods. But only at the 0 X axis value. You can see it on the left side, sticking out from the vertical Y axis. The first picture is fine but then the second shows some of the first chart, then the third shows of both:
Seems like some data is stuck in the view but I use new datasets every time.
Code goes as follows:
func setSwiftUi() {
let formView = SwiftUIStockChart(data: self.chartDataSwiftUI) { [weak self] newData in
self?.dismiss(animated: true) {
}
}
let childView = UIHostingController(rootView: formView)
addChild(childView)
childView.view.frame = chartView.bounds
chartView.addSubview(childView.view)
childView.didMove(toParent: self)
self.chartView.setNeedsDisplay()
self.chartViewAndAxis.setNeedsDisplay()
}
struct SwiftUIStockChart: View {
#State var currentIndex: Int? = nil
#State private var data = SymbolInfoStruct()
private var completion: (SymbolInfoStruct) -> Void
init(data: SymbolInfoStruct, completion: #escaping (SymbolInfoStruct) -> Void) {
self._data = State(initialValue: data)
self.completion = completion
}
func valueStickLabel(value: SymbolInfoStruct) -> some View {
let currentIndex = self.currentIndex ?? (value.chartDates.count - 1)
let formatter = DateFormatter()
if value.dateRange == "day"{
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
let date = formatter.date(from: value.chartDates[currentIndex])!
formatter.dateFormat = "HH:mm"
return Text(formatter.string(from: date))
} else if value.dateRange == "week" {
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
let date = formatter.date(from: value.chartDates[currentIndex])!
formatter.dateFormat = "EE"
return Text(formatter.string(from: date))
} else if value.dateRange == "month" {
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
let date = formatter.date(from: value.chartDates[currentIndex])!
formatter.dateFormat = "MMM d"
return Text(formatter.string(from: date))
} else if value.dateRange == "year" {
formatter.dateFormat = "yyyy-MM-dd"
let date = formatter.date(from: value.chartDates[currentIndex])!
formatter.dateFormat = "MMMM"
return Text(formatter.string(from: date))
} else {
formatter.dateFormat = "yyyy-MM-dd"
let date = formatter.date(from: value.chartDates[currentIndex])!
formatter.dateFormat = "YYYY"
return Text(formatter.string(from: date))
}
}
var isLaserModeOn = false
var showGlowingIndicator: Bool {
switch data.interval {
case "day":
return true // simulate today's data
default:
return false
}
}
func buildMovingPriceLabel(plotData: [CGFloat]) -> some View {
var currentIndex = 0
currentIndex = self.currentIndex ?? (plotData.count - 1)
return HStack(alignment: .bottom, spacing: 1) {
Text(" $")
MovingNumbersView(
number: Double(plotData[currentIndex]),
numberOfDecimalPlaces: 2,
verticalDigitSpacing: 0,
animationDuration: 0.3,
fixedWidth: 100) { (digit) in
Text(digit)
}
.mask(LinearGradient(
gradient: Gradient(stops: [
Gradient.Stop(color: .clear, location: 0),
Gradient.Stop(color: .orange, location: 0.2),
Gradient.Stop(color: .orange, location: 0.8),
Gradient.Stop(color: .orange, location: 1.0)]),
startPoint: .top,
endPoint: .bottom))
}
.rhFont(style: .title3, weight: .medium)
.foregroundColor(.orange.opacity(0.9))
}
var body: some View {
VStack (alignment: .leading, spacing: -10){
RHInteractiveLinePlot(
values: data.chartDataPoints,
occupyingRelativeWidth: 0.9,
showGlowingIndicator: true,
lineSegmentStartingIndices: Array(stride(from: 0, to: data.chartDataPoints.count, by: 5)),
didSelectValueAtIndex: { index in
self.currentIndex = index
},
customLatestValueIndicator: {
},
valueStickLabel: { value in
valueStickLabel(value: data)
})
.foregroundColor(.orange.opacity(0.9))
.font(.headline)
.environment(\.rhLinePlotConfig, RHLinePlotConfig.default.custom(f: { (c) in
c.useLaserLightLinePlotStyle = isLaserModeOn
}))
buildMovingPriceLabel(plotData: data.chartDataPoints)
}
}
}
Any idea how to resolve this?
