We are really excited to announce, that SciChart iOS/ Android / Xamarin v2.1 is released!

If you are using SciChart iOS v1.x or Android v1.x then please note that this update introduces breaking changes and is not a drop-in replacement for SciChart iOS/Android v1. 

What is new in SciChart iOS / Android / Xamarin?

New Features

• SciChart iOS Swift 4 support:

Although we have unofficially supported Swift 4 for a while via our Github and Cocoapod feeds, this official release now includes support for SWIFT 4. The documentation and the examples have been updated.

• SciChart Xamarin now supports Xamarin 11.

• SciChart Pie Chart, SciChart Donut Chart and SciChart Nested Chart types are added to both iOS and Android.

Pie, Donut and Nested Charts are very popular in dashboards, sales reports and many other applications. These are found useful when there is a need to  compare the giving category with the total in one chart. Please see SciChart iOS and SciChart Android examples for these charts. Xamarin.iOS and Xamarin.Android Bindings are added for the above chart types as well.

• SciChart Animations function

We have added animation functions to charts, to let you fade, sweep, or bounce data when data is first added to the chart or when data-points are added. The animations engine is very flexible and powerful and gives your iOS & Android charts that awesome look & feel you are looking for. Be the first one to try those out and make gorgeous applications with SciChart iOS/Android Animated Charts:

• SciChart Trader Showcase

With the high demand in financial applications we have replenished our SciChart Showcase with the Trader Example. It shows how to have multiple chart panes in the application, that are synchronized. There are common candlestick charts combined with the column, band series and volume shown at the main pain at the bottom. You may see how to use the different timescales 5 minutes, 1 hour, 1 day or 1 week. The moving average is there for the demonstration purposes. You may also zoom, pan, show cursor on tap and see the latest values on the chart. You can access the Showcase from our GitHub: SciChart iOS Trader ShowCase and SciChart Android Trader ShowCase.
