我有一个Shinobi甜甜圈图表,我想更改切片标签颜色。
我使用Swift3。图表完美显示,但标签颜色为白色。
class myViewController: UIViewController, SChartDatasource {
@IBOutlet weak var paymentChartView: UIView!
override func viewDidLoad() {
addPaymentInformationChart()
}
func addPaymentInformationChart() {
let chart = ShinobiChart(frame: paymentChartView.bounds)
chart.title = "Payment Information"
chart.autoresizingMask = [.flexibleHeight, .flexibleWidth]
chart.titleLabel.textColor = UIColor.black
chart.datasource = self
paymentChartView.addSubview(chart)
}
/* SChartDatasource methods */
func numberOfSeries(in chart: ShinobiChart) -> Int {
return 1
}
func sChart(_ chart: ShinobiChart, seriesAt index: Int) -> SChartSeries {
let donutSeries = SChartDonutSeries()
donutSeries.style().spokeStyle.showSpokes = true;
donutSeries.selectedStyle().spokeStyle.showSpokes = true;
return donutSeries
}
func sChart(_ chart: ShinobiChart, numberOfDataPointsForSeriesAt seriesIndex: Int) -> Int {
return 3
}
func sChart(_ chart: ShinobiChart, dataPointAt dataIndex: Int, forSeriesAt seriesIndex: Int) -> SChartData {
let dp = SChartDataPoint()
dp.xValue = 0
dp.yValue = 0
if paymentDatasource.count > 0 {
switch dataIndex {
case 0:
dp.yValue = 100.0
break
case 1:
dp.yValue = 200.0
break
case 2:
dp.yValue = 300.0
break
default:
break
}
}
return dp
}
func sChart(_ chart: ShinobiChart, labelForSliceAt sliceIndex: Int, in series: SChartRadialSeries) -> UILabel? {
let sliceLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 21))
sliceLabel.textColor = UIColor.black
switch sliceIndex {
case 0:
sliceLabel.text = "Principal"
break
case 1:
sliceLabel.text = "Interest"
break
case 2:
sliceLabel.text = "Total"
break
default:
break
}
return sliceLabel
}
}
标签文字设置正确但标签颜色不会改变。
我将不胜感激任何帮助
答案 0 :(得分:0)
毕竟我发现我必须更改图表样式才能更改标签样式:
func sChart(_ chart: ShinobiChart, seriesAt index: Int) -> SChartSeries {
let donutSeries = SChartDonutSeries()
donutSeries.style().spokeStyle.showSpokes = true;
donutSeries.selectedStyle().spokeStyle.showSpokes = true;
donutSeries.style().labelFontColor = UIColor.black
donutSeries.selectedStyle().labelFontColor = UIColor.black
return donutSeries
}
