我正在使用charts framework來繪製圖表。我需要在每個酒吧的左側添加一些字符串。在我的代碼總是有兩個酒吧,一個爲收入和一個爲費用。我想把這些字符串顯示在每個欄的旁邊。如何將字符串標籤(xAxis標籤)添加到圖表框架中的水平條上
下面你可以看到我的代碼:
let ys1 = [model.totalIncome, abs(model.totalExpense)]
var yse1 = ys1.enumerated().map { x, y -> BarChartDataEntry in
return BarChartDataEntry(x: Double(x), y: y)
}
let count = 2
let data = BarChartData()
let ds1 = BarChartDataSet(values: yse1, label: "")
ds1.colors = [UIColor.red, UIColor.blue]
// Number formatting of Values
ds1.valueFormatter = YAxisValueFormatter()
ds1.valueFont = UIFont(fontType: .H6)!
ds1.valueTextColor = UIColor.dark_text
// Data set
data.addDataSet(ds1)
horizontalBarChartView.data = data
// General setting
horizontalBarChartView.xAxis.drawLabelsEnabled = false
horizontalBarChartView.setScaleEnabled(false)
// Grid
horizontalBarChartView.xAxis.drawGridLinesEnabled = false
horizontalBarChartView.leftAxis.gridLineDashLengths = [15.0, 15.0]
horizontalBarChartView.leftAxis.gridColor = UIColor.palette_28
horizontalBarChartView.rightAxis.drawGridLinesEnabled = false
// Disable number formatting of leftAxis and rightAxis
horizontalBarChartView.leftAxis.enabled = false
horizontalBarChartView.rightAxis.enabled = false
horizontalBarChartView.xAxis.valueFormatter =
IndexAxisValueFormatter(values: ["Income","Expense"])
horizontalBarChartView.xAxis.granularityEnabled = true
horizontalBarChartView.xAxis.granularity = 1
// setViewPortOffsets
let digitCount = Int(data.yMax).digitCount
let leftOffcet: CGFloat = digitCount > 2 ? CGFloat((digitCount - 1) * 10) : 10.0
horizontalBarChartView.setViewPortOffsets(left: leftOffcet, top: 0, right: 0, bottom: 50)
horizontalBarChartView.leftAxis.axisMinimum = 0
而我的觀點:
lazy var horizontalBarChartView: HorizontalBarChartView = {
let chartView = HorizontalBarChartView()
chartView.contentMode = .scaleAspectFit
chartView.drawBordersEnabled = false
chartView.drawGridBackgroundEnabled = false
chartView.gridBackgroundColor = UIColor.clear
chartView.legend.enabled = false
chartView.chartDescription = nil
chartView.highlighter = nil
chartView.clipsToBounds = true
chartView.translatesAutoresizingMaskIntoConstraints = false
return chartView
}()
我想下面的代碼應該添加這些標籤,但是,它不工作
horizontalBarChartView.xAxis.valueFormatter = IndexAxisValueFormatter(values: ["Income","Expense"])
horizontalBarChartView.xAxis.granularityEnabled = true
horizontalBarChartView.xAxis.granularity = 1
更新
請參閱橙色矩形。我需要這些標籤。
沒有,請參閱我的更新。我需要這些標籤。 –
