This library includes a chart to display accumulated orders in a high-customazible, interactive and Auto Layout capable way.
Just drag and drop the directory DepthChart into your existing project and start using it directly.
You can view and run the example application. Just compile this project.
Otherwise usage is as follows:
private let depthChart = DepthChart()
// ... in intialization add the following:
// add buy orders
depthChart.data.addBuyOrder(with: price, amount: amount)
// add sell orders
depthChart.data.addSellOrder(with: price, amount: amount)
// style (refer to DepthChartStyle.swift)
depthChart.style.xAxisFont = UIFont.systemFont(ofSize: 11)
depthChart.style.yAxisFont = UIFont.systemFont(ofSize: 11)
// define the position of axes
depthChart.xAxisPosition = .top
depthChart.yAxisPosition = .left // or .hiddenBy default, prices are formatted using two fraction digits (8.00 $). You can customize this behavior by providing a delegate:
// ... in intialization add the following:
depthChart.delegate = self
// implement the following methods
func formatXLabel(for value: Double) -> String {
let nf = NumberFormatter()
nf.numberStyle = .currency
// display 8 fraction digits
nf.minimumFractionDigits = 8
nf.maximumFractionDigits = 8
return nf.string(from: NSNumber(value: value))!
}Please understand I created this library within 6 hours of work. It may contain bugs or may be unoptimized. Feel free to contribute.
