// Xamarin Chart Examples

Please note! These examples are new to SciChart Mobile v3 release! SciChart iOS & Android ship with Xamarin.iOS and Xamarin.Android bindings around our native iOS & Android Chart controls, allowing you to create fast & feature rich charts to your Xamarin applications. We include ~90 native iOS examples and 90 Android examples, but now also ~60 Xamarin Chart Examples to help you get started with SciChart. You can download the source for our Xamarin Chart Examples from Github, or browse the source code below.

// Xamarin Surface Mesh Palette Provider 3D Chart

This example showcases how to use PaletteProvider API for a 3D Surface Mesh Chart to color the individual cells of the chart created with Xamarin.iOS and Xamarin.Android.
