SciChart WPF v4.0.6 Build 8482 Released

We are pleased to announce a Stability Update to the SciChart WPF SDK v4.

This release addresses bug fixes which have been reported by our users over the past few weeks. It is therefore recommended for all users of SciChart WPF v4 to update due to the number of minor issues addressed in this patch.

If you are using SciChart v4.x then this update is a drop-in replacement. If you are still using SciChart v3.6.1 we invite you to take a look at SciChart v4 and our migration guide. We’ve made it easier than ever to jump to the latest major version!

SciChart Android / iOS Coming Soon!

Over the past year, we’ve been working hard to port SciChart to iOS / Android and these are going to be released very soon. We are just finalising the packaging, distribution and documentation for SciChart iOS / Android v1 and will be announcing these shortly.

SciChart for Android is shaping up to be the worlds fastest Android Chart by an order of magnitude, capable of drawing millions of points in real-time on Android devices. Perfect for financial, medical or engineering applications, embedded systems and automotive systems.

SciChart for iOS is also capable of drawing millions of points with instant zoom/pan and offers smooth and stutter free real-time charting on iPad and iPhone devices.

Both are going to be announced shortly, but in the meantime, here is a quick preview of SciChart for iOS and Android in the two videos below.
