Question

我制作了一个分为6组的条形图，并且设法设法将它们精确地定位在每个组的下方。现在，问题在于每个标签内部的值都在重复。我的值数组包含6个不同的值，我的标签计数为7。labelCount必须为7，才能使图表正确居中。而且，我也确实将此值设置为6，以为当值格式化程序选择值并且标签仍在重复时，存在索引问题。

我已经尝试将粒度更改为各种值，并且它无法正常工作。我还摆弄了将粒度切换为true或false的方法，但是它也不起作用。

var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun"]

lazy var barChart: BarChartView = {
    let chart = BarChartView()
    chart.translatesAutoresizingMaskIntoConstraints = false
    var inComing = [BarChartDataEntry]()
    var outgoing = [BarChartDataEntry]()
    for i in 0..<6 {
        let entry = BarChartDataEntry(x: Double(i), y: Double.random(in: 10..<100))
        inComing.append(entry)
    }
    for i in 6..<12 {
        let entry = BarChartDataEntry(x: Double(i), y: Double.random(in: 10..<100))

    }
    let set1 = BarChartDataSet(entries: inComing, label: "Incoming")
    let set2 = BarChartDataSet(entries: outgoing, label: "Outgoing")
