我有一个LineChartView,我想显示xAxis的标签。 我的代码如下所示:
chartView.chartDescription?.enabled = false
chartView.drawGridBackgroundEnabled = false
chartView.dragEnabled = !chartView.isFullyZoomedOut
chartView.setScaleEnabled(true)
chartView.pinchZoomEnabled = true
chartView.setViewPortOffsets(left: 20.0, top: 0.0, right: 20.0, bottom: 0.0)
chartView.legend.enabled = true
chartView.legend.textColor = legendColor
chartView.legend.form = .empty
chartView.leftAxis.enabled = false
chartView.leftAxis.spaceTop = 0.4
chartView.leftAxis.spaceBottom = 0.4
chartView.rightAxis.enabled = false
chartView.xAxis.enabled = true
chartView.xAxis.labelTextColor = UIColor.black
chartView.xAxis.valueFormatter = self
chartView.xAxis.drawGridLinesEnabled = false
chartView.xAxis.drawLabelsEnabled = true
chartView.xAxis.drawAxisLineEnabled = false
chartView.highlightPerTapEnabled = false
chartView.highlightPerDragEnabled = false
if lineChartData.entryCount > 0 {
chartView.data = lineChartData
}
chartView.noDataText = NSLocalizedString("No chart data available", comment: String())
chartView.maxVisibleCount = 12
chartView.delegate = self
和
extension ChartCell: IAxisValueFormatter {
func stringForValue(_ value: Double, axis: AxisBase?) -> String {
return "foo"
}
}
答案 0 :(得分:1)
您必须在下面进行设置:
chartView.xAxis.labelPosition = XAxis.LabelPosition.bottom
