We are excited to announce SciChart JavaScript ultra-high-performance charts version is 1.2 released!

It consists of new features, great improvements, and bug fixes. It is suggested for all the users of SciChart.js v 1.1 and earlier to upgrade to this version.

What’s new in SciChart.js v1.2?

New Features

1. New Annotations Types: Horizontal Line, Vertical Line, and Axis Marker Annotation
   The HorizontalLineAnnotation draws a horizontal line at Y1 and VerticalLineAnnotation draws a vertical line at X1. The HorizontalLineAnnotation may be stretched (horizontally) across the chart or drawn to a specific X-value, same as VerticalLine annotation can be all across the chart or just to a specific point.

See Annotations are easy example.

2. Annotations Editable
Now you can select an annotation, then drag it by the corners to resize and move it around the chart.

All the annotations are editable now, including Line Annotation, Box Annotations, Text Annotations, Horizontal and Vertical Annotations, and Custom Annotation.

See Editable JavaScript Annotations example.

3. Step or Digital Chart types: Step Line, Step Band, and Step Mountain chart types

The step or digital chart types are often used to visualize data that changes at irregular intervals. SciChart.js now supports digital line, digital band and digital mountain series that can be used in rendering high performance visualization.

See JavaScript Step (digital) Line Chart, JavaScript Step (digital) Band Chart, JavaScript Step (digital) Mountain / Area Chart documentation.

4. Styling with the borders properties

SciChart.js now allows even more flexible styling of your javascript charts. You can easily edit the thickness and color of the borders around any part of a chart: chart surface itself (viewportBorder), the render surface (canvasBorder), X and Y axis (axisBorder), even if there is more than one of each.

See JavaScript Chart Margin and Padding documentation.
