SciChart iOS, macOS, and Android SDK v4.2 Released!

We are pleased to announce that the SciChart iOS, macOS, and Android v4.2, has now been released!  There is a new feature, a number of improvements, memory leaks and critical bugs fixed. It is recommended for all users of SciChart to update to the latest version! Please see more information below.

What is new in SciChart v4.2

New Series Value Modifier Feature

In the new version of SciChart iOS, macOS and Android we have added an often requested by users in Financial and Trading feature, the SeriesValueModifier. This is a modifier that displays the last series value as a marker on the YAxis. This modifier automatically creates one marker per series and places it at the series latest Y-Value on the Y axis.

This helps you to know what the latest value is no matter where you panned the screen to.

See: iOS and macOS series value modifier example and
Android series value modifier example.

The application distribution issue with macOS BigSur and XCode 12 fixed

From this version following Apple, we have bumped the minimum supported iOS version to 9. Everything worked well until macOS BigSur and XCode 12 were released. With that many of our users reported that they were unable to distribute theirs apps through the AppStore. This has been fixed now!
