BarChart does not render with multiple data sets

[software-2]

I'm trying to create a bar chart using multiple data sets, but when I try to provide multiple sets to the BarChartView no bars are rendered.

let barView = BarChartView()

let set1 = BarChartDataSet()
set1.addEntry(BarChartDataEntry(x: 1, y: 1))
let set2 = BarChartDataSet()
set2.addEntry(BarChartDataEntry(x: 2, y: 2))

barView.data = BarChartData(dataSets: [set1, set2])

contentView = barView

In the above example, I would expect two bars to be displayed. However, no bars will appear at all.

If I provide only one data set, the chart will render as expected.

barView.data = BarChartData(dataSets: [set1])

@liuxuan30 📊支持左右两侧Y轴值不一样 比如，左侧是最大是100 右侧最大值是1 000 000 ？
