问题
I'm building a Xamarin Forms project for a client and we need a graphing library that will handle data live streamed as a line chart that connects points. I'm relatively new to the Xamarin community and was wondering if one of the more knowledgeable developers could point me toward a good library for this.
I saw Syncfusion Essential Studio but 2k a license is not in the budget and OxyPlot, but its website doesn't work (http://oxyplot.org/).
The first target platform is iOS.

XLabs has basic charting for iOS/Android/WinPhone:
- Charting : https://github.com/XLabs/Xamarin-Forms-Labs/wiki/Charting
Personally the XLabs version was too simple for our needs, so we either:
1) Use native charting libraries via Jar and sharpie binding projects
- There are lots of options in the paid and OSS worlds for Android and iOS in this regard.
2) Use NGraphics to draw the graph using primitives within Xamarin.Forms apps

Take a look at SciChart for Xamarin - which provides rich, interactive high performance charts for iOS & Android.
Examples are hosted at Github: https://github.com/abtsoftware/scichart.xamarin.examples
A getting-started youtube video is here: https://www.youtube.com/watch?v=wYdab-0XHMA
Disclosure: I am the tech lead on the SciChart xamarin project

If you are looking for free controls you can use charting controls from Xamarin-Forms-Labs: Xamarin-Forms-Labs Charting
You can also use Telerik Charting Controls which costs $799

I ended up going with Telerik's UI for Xamarin mainly due to business concerns. We have now switched to SciCharts.
Another charting possibility I discovered is the Xamarin.Forms Controls from Infragistics.
