SciChart JavaScript Charts v1.3 Released!

SciChart JavaScript Charts v1.3 Released!

We are excited to announce SciChart JavaScript ultra-high-performance charts version is 1.3 released!

It consists of new features, great improvements, and bug fixes. It is suggested for all the users of SciChart.js v 1.2 and earlier to upgrade to this version.

What’s new in SciChart.js v1.3?

New Features

Spline Series

Spline Line Chart
SciChart.js features a native spline-line (smoothed line) series. It provides aesthetically attractive, yet high-performance smoothed line charts for web applications. Given raw data, which can be a large number of points, our customers needed to see the smoothed line to help analyze the data.

Spline Line series uses Bezier interpolation between data-points. Our intelligent and dynamic smoothing keeps the performance outstanding and allows visualizing hundreds of thousands and even millions of data-points.

See Spline Line Series Example.

Spline Mountain Charts
SciChart for JavaScript 1.3 features a spline mountain or area series which provides aesthetically pleasing, high performance smoothed mountain/area charts for JavaScript apps.
Again, performance is excellent thanks to our dynamic smoothing and this chart type allows interactive frame-rates into the hundreds of thousands of points.


Spline Band Chart
SciChart.js provides the API for slick smoothed band chart type as well. This allows you to create high performance smoothed band / high-low fill charts for JavaScript web applications.

See Spline Band Series Example.

JavaScript Chart Animations

SciChart’s JavaScript Chart now features a new JavaScript Chart Animation API. Animated JavaScript charts will help you create captivating web applications. There are four standard animation types introduced in SciChart.js, including Wave, Sweep, Fade and Scale animations.

Wave JavaScript Chart Animation (see example)

Animation API is flexible so you can control when the animation starts and stops, the delay, as well as duration. You can also combine different animations for one chart!

Spline Series and Animations

It is an interesting and unique case of combining the spline algorithms with applying animations on one series. Please see the example and the source code for more information: Animated JavaScript Spline Area Chart.

Dashed Line Styling

SciChart.js v 1.3 introduces more options to style your chart by adding the dashed line styling.

See Dashed Line Styling Example.
