JSXGraph v1.00.0 released!

Posted on by

Dear friends of ITEMS and JSXGraph,

a few days ago, we released JSXGraph v.1.00.0. After 12 years of development we think JSXGraph is more than ready to leave with version 1.00.0 the unofficial beta-status.

We heartfully thank all the developers out there who use JSXGraph since many years to produce mathematical visualizations for countless e-learning environments from primary school to university level.

Also, we want to invite you to the 1. JSXGraph conference on 8.-9. October 2020 at the University of Bayreuth, Germany. We want to bring together JSXGraph users, developers and content developers to exchange ideas and learn from each other.

Moreover, at https://ipesek.github.io/jsxgraphbook/ a tutorial for programming JSXGraph is in development. Stay tuned!

New in v1.00.0

The last release was version 0.99.7 in May 2018, a big pile of improvements has been incorporated since then. In this post, we want to give just a short overview of the changes and improvements since version 0.99.7. In the following days, we will publish a series of posts where the new possibilities are explained together with examples.

Compatibility

  • To the best of our knowledge, version 1.00.0 contains only one change which might request action from content developers: JessieCode parse errors are now handed over to the application and can/must be caught by try {} catch (e) {}. Before, just a console.log() message was written by JessieCode.
  • The good news are that Safari and wkwebview on iOS 13+ switched to pointer events. That is, all major browsers now use pointer event.
  • Since Safari 12, board.renderer.screenshot() also supports texts in Safari and therefore behaves similar as in Chrome and Firefox.

New Features and Improvements

  • Polygon / curve clipping and boolean operation on curves are now enabled. This allows intersection, union or difference of curves, polygones or circles, see API docs.
  • New math functions: cot, acot, nthroot, cbrt, binomial. Available e.g. as JXG.Math.cot. nthroot(a, n) returns the n-th real root of a, where n is an integer. cbrt is the cubic root.
  • JXG.Math.pow: is now able to compute x^(1/n) for x<0 and $n$ an odd integer.
  • Add board attributes showFullscreen and fullscreen, see API docs.
  • New board attribute maxBoundingBox, see API docs.
  • Faces for hatch marks and ticks |><, see API docs.
  • Create parabola given by a point and a pair of coordinate pairs.
  • Styling and highlighting of navigation bars with CSS
  • Add new parameter delay for CoordsElement.startAnimation()
  • Polar grid
  • New attribute highlightSize for arrow heads.
  • Reflection, mirroring of polygons
  • New attribute for labels autoPosition: true/false enables automatic positioning of labels which avoids overlapping of labels.
  • screenshot and base64 dumps include images now (dumpToURI)
  • API documentation contains many new examples and documentation of charts.
  • Curve plotting: massive speed improvements and plotting precision
  • Multi-touch rotations are much more stable for pointer events
  • Pointer events use different precision when using pen, mouse or touch. New events for pen: pendrag, pendown, penmove.
  • Massive speed-up if many elements are deleted
  • Improved pan / pinch-to-zoom handling

We thank all contributors which supplied patches, bug reports and suggestions for improvements.

For a full list of all changes see the CHANGELOG.

Enjoy,

Matthias Ehmann, Michael Gerhäuser, Bernat Martinez, Carsten Miller, and Alfred Wassermann
