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 addresses the lack of explanatory tooltips for emoji used next to diagram type names in the "Diagram Syntax" section of the documentation. The proposal suggests adding tooltips to these emoji to help users better understand the meaning and information conveyed by each icon, improving overall clarity and usability.
- log scale for
xychart-beta: This issue proposes adding ascalestring field to thexychart-betacomponent that defaults tolinearbut can also acceptlogas an option, enabling logarithmic scaling for charts. This enhancement aims to allow users to maintain version control over graph data in true (non-logged) values while displaying the data on a logarithmic scale, with potential for future extension to other scale types. - Unable to Style Sequence Diagram Title: This issue reports a problem with the Mermaid sequence diagram feature where users are unable to change the font size of the diagram title, resulting in titles that appear very small and difficult to read. The user notes that while other Mermaid graph types support title styling attributes, such as font size, this functionality is not yet implemented for sequence diagrams, and the current workaround involves using a Markdown title instead.
- SVG rendering formatting issues with markdown input: This issue addresses problems with SVG rendering when nodes in a diagram use markdown formatting, resulting in inconsistent visual output such as added height or text being cut off in the SVG files. Specifically, these formatting issues occur when opening the SVG in a new tab or downloading it from the editor, causing discrepancies between the expected and actual appearance of the diagram elements.
- 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 properties on an undefined object, specifically involving Mermaid's API prototype.
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: 3
Summarized Issues:
- Styling and Customization Enhancements: This topic covers requests for improved visual customization options in Mermaid diagrams, such as adding class-based styling to Kanban board tasks for better visual differentiation beyond existing priority-based colors. Users seek more flexible and user-friendly ways to style and shape diagram elements without redundant syntax.
- issues/6899
- Syntax and Error Reporting Improvements: This topic involves the need for clearer and more precise syntax error messages, especially when dealing with special characters in labels that require escaping or quoting. Current error messages are vague, making it difficult for both humans and AI to troubleshoot Mermaid diagram issues effectively.
- issues/6904
- Node Shape Customization: This topic addresses the challenge of changing node shapes, such as from rectangle to diamond, while preserving the node's text without repeating it in the syntax. Users want simpler syntax to modify node shapes without redundancy.
- issues/6906
