我创建了一个条形图,其中包含xAxis的9个类别标签: [" Foods"," House Loan"," Insurance"," Petrol"," Saving",&#34 ; Train"," Others"," Books&杂志","停车场"]
但是在图表中它只显示: 食品,保险,储蓄,其他和停车场
任何人都知道如何解决它?
这里是设置xAxis的源代码
func setChart(dataPoints: [String], values: [Double]) {
var dataEntries: [BarChartDataEntry] = []
for i in 0..<dataPoints.count {
let value = values[i] as Double
let dataEntry = BarChartDataEntry(x: Double(i), y:value)
dataEntries.append(dataEntry)
}
let chartDataSet = BarChartDataSet(values: dataEntries, label: "Total Amount")
var colors: [UIColor] = []
for _ in 0..<dataPoints.count {
let red = Double(arc4random_uniform(256))
let green = Double(arc4random_uniform(256))
let blue = Double(arc4random_uniform(256))
let color = UIColor(red: CGFloat(red/255), green: CGFloat(green/255), blue: CGFloat(blue/255), alpha: 1)
colors.append(color)
}
chartDataSet.colors = colors
chartDataSet.colors = ChartColorTemplates.joyful()
barChartView.chartDescription?.text = ""
barChartView.xAxis.labelPosition = .bottom
barChartView.xAxis.drawGridLinesEnabled = false
barChartView.xAxis.granularityEnabled = true
barChartView.xAxis.granularity = 1.0
barChartView.xAxis.decimals = 0
let chartData = BarChartData()
chartData.addDataSet(chartDataSet)
barChartView.data = chartData
barChartView.xAxis.valueFormatter = self
let format = NumberFormatter()
format.numberStyle = .decimal
let formatter = DefaultValueFormatter(formatter: format)
chartData.setValueFormatter(formatter)
barChartView.animate(xAxisDuration: TimeInterval(1))
}
答案 0 :(得分:1)
只需设置标签计数即可。 barChartView.xAxis.labelCount = dataPoints.count
