如何在IOS图表中设置x轴标签之间的空间？

Question

我一直面对这个问题。我希望在我的ios图表中的x轴标签之间设置相等的空间。我提到了this解决方案并将代码应用为lineChartView.xAxis.avoidFirstLastClippingEnabled = true，但它没有成功。然后我确实将值设置为false然后它给了我一些相等的间距，但现在我的第一个和最后一个x轴标签被隐藏在图表中。请帮我解决这个问题。这是线图自定义的代码：

func setXaxis(){
    lineChartView.xAxis.labelPosition = .bottom
    lineChartView.xAxis.avoidFirstLastClippingEnabled = false
    lineChartView.xAxis.forceLabelsEnabled = true
    lineChartView.xAxis.labelPosition = XAxis.LabelPosition.bottomInside
    lineChartView.xAxis.drawGridLinesEnabled = false
    lineChartView.xAxis.labelTextColor = chartcolor
    lineChartView.xAxis.labelCount = 6
    lineChartView.xAxis.xOffset = 10


}
func setYaxis(){
    lineChartView.leftAxis.labelPosition = YAxis.LabelPosition.insideChart
    lineChartView.leftAxis.labelTextColor = chartcolor
    lineChartView.leftAxis.gridColor = chartcolor
    lineChartView.leftAxis.labelCount = 5
    lineChartView.leftAxis.yOffset = 6
    lineChartView.setViewPortOffsets(left: 0, top: 0, right: 0, bottom: 0)

}
func setChart(){
    lineChartView.noDataText = ""
    lineChartView.dragEnabled = false
    lineChartView.setScaleEnabled(false)
    lineChartView.pinchZoomEnabled = false
    lineChartView.drawMarkers = true
    lineChartView.backgroundColor = bluecolor
    lineChartView.rightAxis.enabled = false
    lineChartView.legend.enabled = false
    lineChartView.chartDescription?.enabled = false

}

这些是我的截图。

何时： lineChartView.xAxis.avoidFirstLastClippingEnabled = true

何时： lineChartView.xAxis.avoidFirstLastClippingEnabled = false
