ios - 将 X 轴标签分配给图表框架

Question

我正在使用 Charts框架。
我能够将数据添加到图表中，但无法更改图表上的 X 轴标签。

早些时候，可以使用以下方法完成:

变量:

var months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"]

var sales = [230, 220, 240, 170, 90, 60, 150, 140, 160, 170, 140, 250]

ViewDidLoad:

let salesEntry1 = BarChartDataEntry(x: 0.0, y: 250)
    let salesEntry2 = BarChartDataEntry(x: 1.0, y: 260)
    salesEntries.append(salesEntry1)
    salesEntries.append(salesEntry2)


    let chartDataSet = BarChartDataSet(values: salesEntries, label: "Sales")

    let chartData = BarChartData(dataSet: chartDataSet)
    barChart.data = chartData

更新:

Answer 1

目前由于旧的初始化程序不可用

代码:

let labels = ["Value 1", "Value 2"]
barChart.xAxis.valueFormatter = IndexAxisValueFormatter(values: labels)

为每个条设置标签

设置 粒度 X 轴为 1

 barChart.xAxis.granularity = 1

Note: This is a Swift 3 issue for Charts (v3.0.1)
