Format the Y-axis scale values anxious anxious anxious

4.0 latest version of Charts
Question: This chart is a MPAndroidChart ported to Android.
MPAndroidChart has a method
public String getFormattedValue(float value, AxisBase axis) {}
This can get the automatically generated Y-axis scale value, and then it is very convenient to solve the scale formatting (for example: 20000.22 converted into 2.2万)
Is there a similar method for Charts in iOS?
Thanks, very anxious

4.0最新版本的Charts
问题：这个charts是移植的那个安卓的，MPAndroidChart这个三方，
MPAndroidChart有方法public String getFormattedValue(float value, AxisBase axis) {}
可以拿到自动生成的Y轴的刻度值，然后很方便的解决刻度格式化（例如：20000.22转成2.2万）
iOS 的Charts有类似方法吗？
谢谢，很着急
