JSXGraph v1.13.1 is a patch release that introduces subtle improvements and resolves various bugs.

As is common after a major version release, bug reports began to arrive. This time, special thanks go to Tom Berend, who reported a significant number of persistent issues.

The most critical bugs affected polyhedron3d elements and the Line.getAngle() method. Additionally, several mistakes in the API documentation have now been corrected. This patch also allowed us to upgrade MathJax to v4 within the documentation.

Enjoy, Alfred

We have updated the JSXGraph website to make it easier to navigate and discover relevant content.

What’s new?

• A redesigned website structure with clearer and more intuitive categories.
• A new Authoring with AI section featuring resources and guidance on creating interactive JSXGraph illustrations with the help of AI.
• JSXGraph AIR for Visual Studio Code, a new VS Code tool that enables AI-assisted authoring with live preview and convenient export options.

We hope these improvements make it even easier to learn, explore, and create with JSXGraph.

Best regards,

Carsten Miller

JSXGraph version 1.13.0 introduces a wealth of new features, improvements, and bug fixes. This release represents the culmination of over 400 commits, with pull requests from Christian Perfect, CloudShannon, and Andreas Walter. Thank you so much!

This version finally introduces the convenient shortcut JXG.board(...), replacing the more verbose JXG.JSXGraph.initBoard(...), see the API docs. Similarly, JXG.appBox(...) now enables the creation of a JSXGraph construction wrapped within a surrounding div element. Additionally, JSXGraph elements can be positioned outside the main board and into this wrapper. This behavior is controlled by the clip attribute of JSXGraph elements. The motivation behind appBox is to allow non-mathematical elements, such as sliders and text labels, to be placed outside the board area; see the API docs for an example.

3D support has been massively improved in this version. In particular, rendering speed has increased significantly. Previously, surfaces were displayed only as wireframe models. While this remains possible, surfaces can now utilize the polyhedron3d element for display. Three rendering types are available: 'shader', 'colorarray', and 'colormap'. You can view examples (along with source code) in our examples database:

• 3D parametric surface with colorarray
• 3D parametric surface with type shader
• 3D parametric surface with type colormap

One highly requested feature is the new board attribute cssStyle, which allows authors to style the hosting div element directly. See the example here. This is particularly helpful if the author lacks access to the surrounding HTML.

Further improvements include enhanced statistics capabilities. With JXG.Math.Statistics.boxplot(data), it is now possible to compute the quantiles and outliers of a dataset. The boxplot element can also display outliers conveniently; see the example here.

This release includes a few pull requests that appear to have been assisted by AI. AI tools helped detect bugs in various math functions and generated corresponding unit tests. The good news is that there were not many bugs, and they primarily affected rare edge cases.

Finally, many thanks to all contributors. This project would not be possible without your bug reports, comments, and pull requests.

Enjoy, Alfred

we are pleased to announce the 7th International JSXGraph Conference, taking place online from 6–8 October 2026.

Conference website: https://jsxgraph.org/conf2026/

The conference brings together developers, educators, instructional designers, and researchers who are interested in using JSXGraph to enrich the digital teaching and learning of STEM subjects. Whether you are an experienced JSXGraph user or are just beginning to explore its possibilities, the conference offers an opportunity to exchange ideas, share experiences, and learn from the community—regardless of your location.

The conference will be held entirely online, enabling participants from around the world to attend and contribute without the need for travel. Participation is free of charge; however, all attendees are kindly requested to register.

We warmly invite contributions in the form of talks or workshops. Possible topics include:

• concepts, experiences, and workflows involving JSXGraph,
• applications, projects, and best practices,
• pedagogical approaches and teaching concepts,
• JSXGraph integrations and plug-ins,
• extensions and plug-ins developed for JSXGraph.

Deadline for submission of talks and workshop proposals: September 18th, 2026

Further information about the online conference platform and technical details will be announced in due course.

The 7th International JSXGraph Conference 2026 is organized by the Center of Mobile Learning with Digital Technology at the University of Bayreuth.

We look forward to welcoming you online in October 2026.

With best regards,

Carsten Miller and Alfred Wassermann Conference Organizers

This release is identical to v1.12.1, only a few unnecessary zip files had to be deleted. Otherwise the package size at the CDN jsdelivr would have been too large. That is, v1.12.1 is not available on jsdelivr, but v1.12.2 is.

Enjoy, Alfred

JSXGraph v1.12.1 is a patch release that adds some subtle improvements and addresses a few annoying bugs.

The update addresses the following issues (among others):

• Increased precision for intersections (points) of curves with curves or lines
• The output format of polyhedron.toSTL() is now correct
• Some smartlabels were broken
• The handling of attribute frozen is further improved
• Improvement of the API docs
• Security: replaced some innerHTML by innerText
• Arrow heads in SVG take the CSS color of the line
• jsxgraph.css now contains a version string

In particular, the change of the intersection algorithm for curves might cause problems in existing constructions - even if we tried to make it as backwards compatible as possible. Please report any issues with intersection points, we will try to find a solution.

For the full list of changes see CHANGELOG.md.

Enjoy, Alfred

JSXGraph v1.12.0 mainly improves 3D functionality: it is now able to read and write polyhedra in the STL file format (ASCII only, so far), 3D transformations have been further improved.

JSXGraph has updated its logo. It can be downloaded in many flavors from the new designed homepage https://jsxgraph.org. The copyright string is now much shorter and contains the new logo. With the new board attribute showLogo it is possible to show just the logo.

The use of the attribute frozen which makes the position of elements independent of the zoom level is now much simplified. This is useful especially for sliders. Implicit curves are now clipped and don’t overlap their domain anymore.

Additionally, 3D performance could be improved and multiple bugs were fixed.

Enjoy, Alfred

JSXGraph has a new look and it’s more than just a facelift:

The JSXGraph logo comes in three layouts (text, square, banner) each suited for different uses. Download the various logo files and versions here.

Evolving the JSXGraph Logo

The JSXGraph logo has undergone a thoughtful redesign—one that remains rooted in the mathematical essence of JSXGraph while embracing new dimensions, both literally and conceptually.

At the heart of the new design is the familiar graphical element of the JSXGraph board.

It continues to serve as a visual anchor, preserving the connection to JSXGraph’s core identity.

What sets the redesign apart is the introduction of a subtle 3D component—an elegant nod to JSXGraph’s evolving capabilities, particularly its support for three-dimensional constructions and visualizations.

This updated visual identity does more than refresh the look. It reflects JSXGraph’s broadened scope in dynamic, interactive mathematics—while staying anchored in its foundational concepts.

The circle continues to represent the domain of interactive geometry, highlighting JSXGraph’s strength in constructing and exploring geometric figures.

The coordinate system, in turn, stands for the representation of function graphs and curves, emphasizing the framework’s capabilities in plotting and analyzing mathematical relationships.

The new logo stands as a forward-looking symbol of JSXGraph’s mission: to make mathematics interactive, multidimensional, and accessible—empowering a new generation of learners, educators, and innovators:
