我已经将我的价值存储在核心数据中并在BarChart上显示了。
我的类别数量是8.5和420.10。
但是条形图上的显示是8和420。
我应该如何设置十进制值?
var dataEntries: [BarChartDataEntry] = []
for i in 0..<dataPoints.count {
let value = values[i] as Double
print("value=\(value)")
let dataEntry = BarChartDataEntry(x: Double(i), y:value)
dataEntries.append(dataEntry)
}
let chartDataSet = BarChartDataSet(values: dataEntries, label: "Total Amount")
chartDataSet.colors = [.red, .yellow, .green, .blue, .brown]
chartDataSet.colors = ChartColorTemplates.joyful()
barChartView.xAxis.labelPosition = .bottom
barChartView.chartDescription?.text = ""
barChartView.xAxis.drawGridLinesEnabled = false
barChartView.leftAxis.drawLabelsEnabled = false
barChartView.leftAxis.granularityEnabled = true
let chartData = BarChartData()
chartData.addDataSet(chartDataSet)
barChartView.data = chartData
最佳答案
我得到答案:
let format = NumberFormatter()
format.numberStyle = .decimal
let formatter = DefaultValueFormatter(formatter: format)
chartData.setValueFormatter(formatter)
