Hello Dang,

You can find an example of configuring the Axes like that here in the Axes Overview documentation (see the "Spending on Education" example). In addition to configuring the Axes, take a look at how to create a LineSeries here and a ColumnSeries here.

If you'd like to explore the full examples, you can find them on your machine at: C:\Program Files (x86)\Telerik\UI for Xamarin R3 2016\Examples\iOS 

After opening the solution, find the Multiple Axes chart demo here (for your convenience, I've pasted in the code at the end of this replyt)




Please let us know if you have any further questions.
