2.2 Top 5 Stale Issues:
We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.
- Tooltips for emoji in Diagram Syntax doc tree: This issue proposes adding tooltips to the emoji displayed next to the names of various diagram types in the "Diagram Syntax" section of the documentation tree. The goal is to help users understand the meaning of these icons, as currently there is no reference or explanation available, causing confusion even for experienced users.
- log scale for
xychart-beta: This issue proposes adding ascalestring field to thexychart-betacomponent that defaults tolinearbut can also acceptlogas an option, enabling the plotting of logarithmic scales while maintaining version control of the original non-logged data. The enhancement aims to support future extensions to other scale types and includes an example demonstrating how to specify the log scale for chart axes and data series. - Unable to Style Sequence Diagram Title: This issue describes a problem where users are unable to change the font size of the title in sequence diagrams created with Mermaid, resulting in titles that appear very small and difficult to read. The reporter notes that while other diagram types in Mermaid support title styling attributes, such as font size adjustments, this functionality is currently missing for sequence diagrams, leading to a reliance on Markdown titles as a workaround.
- SVG rendering formatting issues with markdown input: This issue addresses problems with SVG rendering when nodes in a Mermaid diagram contain markdown formatting, resulting in inconsistent node heights and text being cut off in the SVG output. Specifically, opening the SVG in a new tab causes additional height to be added to the node, while downloading the SVG leads to text truncation without adjusting the node height, affecting the visual accuracy of the rendered diagrams.
- Vite build error with mermaid version 10.9.0: This issue describes a problem encountered when building a Vue 3 and Vite application that uses Mermaid version 10.9.0 to render graphs. While the development server runs without errors and displays the graphs correctly, the build process fails on application startup with a TypeError related to setting a property on an undefined object, preventing the Mermaid graphs from rendering as expected.
2.3 Open Issues
This section lists, groups, and then summarizes issues that were created within the last week in the repository.
Issues Opened This Week: 5
Summarized Issues:
- Rendering Issues in Diagrams: Several issues affect the visual correctness of Mermaid diagrams, including incorrect endDate display in Gantt charts when excluding dates like weekends, and improper rendering of multiple arcs looping on the same node in FlowChart and StateDiagram. Additionally, setting securityLevel to "sandbox" causes labels to render with escaped HTML tags, leading to unintended output in flowcharts.
- [issues/6884, issues/6888, issues/6889]
- Documentation Display Problem: The Mermaid.js documentation intro page has a broken image link that prevents the image from displaying properly across multiple browsers, impacting user experience on the site.
- [issues/6885]
- Educational Development Plan for Paudi Bhuyan Tribe: A detailed, phased educational development plan is proposed for the Paudi Bhuyan tribe, focusing on socio-cultural analysis, community-led research, strategic intervention, capacity building, and continuous monitoring to enhance access, retention, learning outcomes, and aspirations. This comprehensive approach aims to address multiple facets of educational improvement within the community.
