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 explaining their significance, which can lead to 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 logarithmic scaling of charts. This enhancement would allow users to maintain version control over graph data in its original linear form while displaying the data on a logarithmic scale, with potential for future extension to other scale types. - 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 rendered diagrams.
- Vite build error with mermaid version 10.9.0: This issue describes a build error encountered when using Mermaid version 10.9.0 in a Vue 3 and Vite application. While the Mermaid graphs render correctly during development, the application fails to start after building, throwing a "TypeError: Cannot set properties of undefined (setting 'prototype')" related to Mermaid's internal code.
- Update packet diagram to use the new class based approach in the DB: This issue involves updating the packet diagram to adopt a new class-based approach in the database, which aims to improve the structure and management of diagram data. This change is intended to enhance parallel rendering by ensuring that each diagram maintains its own data independently, preventing any data spillover between different diagram parsings.
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: 8
Summarized Issues:
- Diagram Layout and Styling Issues: Several issues address problems with diagram appearance and styling in Mermaid. These include difficulties with applying color styles to edges using IDs and classes, incorrect rendering of notes in state diagrams, and exported Git graph images not retaining custom themes, all of which affect the visual consistency and expected output of diagrams.
- issues/6784, issues/6788, issues/6790
- Text Rendering Problems: There are issues related to text display within Mermaid diagrams, such as italicized text in flowchart nodes being cut off on the right side across different fonts. This problem impacts readability and the professional appearance of diagrams.
- issues/6787
- Feature Requests for Diagram Flexibility: Requests have been made to improve diagram customization, including adding a "compact mode" to reduce node height and vertical spacing for better space efficiency, and enabling subgraphs to have independent directional flows differing from the main graph. These features aim to enhance diagram usability and design flexibility.
- issues/6781, issues/6785
- Gantt Chart Scheduling Bug: The Gantt chart feature has a bug where the
excludesparameter incorrectly adds duration to tasks scheduled between two dates, leading to discrepancies between expected and actual task end dates. This issue affects the accuracy of project timelines. - issues/6794
- Type Errors in Dependencies: The
@iconify/utilspackage causes type errors when building Mermaid in strict type mode due to unresolved upstream type problems. Although a fix has been proposed, it is not yet fully suitable for integration, impacting the build process. - issues/6791
