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
