ios图表水平条形图问题

自从我更新到ios图表的最新版本（3.0.0）以来，我在水平条形图方面遇到了许多问题

首先，我在图表上有x轴的标签。有了新版本的ios图表，我不得不编写自己的格式化程序，然而现在只有每秒钟显示一次标签。第二个问题是杆未达到y轴上指示的值。我的意思是，如果我给条带一个值4，条带的高度实际上不够长，无法到达y轴上的4.0标签。这两个问题如图所示

以下是我的值格式化程序代码：

@objc(BarChartFormatter)

公共类BarChartFormatter:NSObject、IAxisValueFormatter{

var labelArray : [String] = ["text1", "text2", "text3", "text4", "text5", "text6", "text7", "text8", "text9", "text10"]


public func stringForValue(_ value: Double, axis: AxisBase?) -> String {
    return labelArray[Int(value)]
}

}

这是条形图的代码
