Sample

Use a declarative syntax to build your k-line chart like SwiftUI. It's simpler and easier to read.

chartView.descriptor = ChartDescriptor(spacing: 0) {
    ChartGroup(height: 200) {
        GridIndicator(lineWidth: 1 / UIScreen.main.scale, color: .Stockee.border)
        YAxisAnnotation()
        CandlestickChart()
        MAChart(configuration: .init(period: 5, color: .yellow))
        MAChart(configuration: .init(period: 10, color: .teal))
        MAChart(configuration: .init(period: 20, color: .purple))
    }

    ChartGroup(height: 18) {
        TimeAnnotation(dateFormat: "HH:mm")
        SelectedTimeIndicator()
    }
}

关于添加Logo图片的问题

您好，如果想给K线图表添加一个类似于Logo的图片控件，且Logo不能遮蜡烛图，请问在哪个类或者哪个层级添加呢；

Memory Leak

Hello Octree.
I tried to use your excellent library Stockee.
But I have an issue:

when using it with SwiftUI after the deallocation of the UIViewController CharView stayed in memory.
This is a screenshot from the memory graph.
There is no ViewController, but CharView with Captions and Interactions are in memory, loaded three times.

After that, I tried to test the Demo from the package. And, unfortunately, receive memory leaks.
I added a simple UI Controller before ChartController:

I tapped the button and returned from the chart several times, and every time, memory allocation grew.
These are screenshots from the XCode Instruments:

I am not a confident developer and can't fix it myself.
I may have used the Package in the wrong way.

Or if it is an issue, could you help to resolve it?
