Obsidian plugins with #excalidraw#

The Excalidraw Math Plotter plugin adds function graph plotting inside Excalidraw drawings. It lets you enter expressions that use x, preview the curve while adjusting optimization and insert the result with configurable stroke colour, width and graph styling. You can control tick marks, grid lines, arrows and numeric labels, and use quick presets for common functions such as sine, cosine and parabolas. The parser is based on mathjs, so it supports basic, trigonometric, logarithmic and combined expressions. It also handles discontinuities such as tan(x) and 1/x, and uses the Ramer Douglas Peucker algorithm to reduce points efficiently. The command runs from an open Excalidraw drawing and requires the Excalidraw plugin to be installed and enabled.

The Obsidian Mobile PDF Exporter plugin exports notes from mobile and desktop into PDF, DOCX, PPTX, PNG and self contained HTML while keeping native text, embedded images, links and much of the rendered layout. It opens an export panel before each run with controls for page size, orientation, margins, content scale, headers, footers, color mode, export mode, output location and whether to open the result after saving. The plugin works from the active reading or editing surface, preserves Markdown styling, tasks, tables, quotes, callouts, code blocks, math, embeds and NoteDraw content, and writes a selectable PDF text layer with matching visuals. Direct .excalidraw.md files can be exported as image PDFs, and full CJK text export depends on a local font file when the embedded subset is not enough.

The Obsidian Math+ plugin speeds up math note taking by inserting dedicated math blocks that accept LaTeX or more natural equation input, then render it directly in the note. In live preview, each block can switch into a drawing layer backed by Excalidraw, so handwritten marks and freeform annotations can sit on top of the rendered equation and be saved as SVG. Settings cover where drawing data is stored, custom shortcuts that translate typed operators into LaTeX patterns, default drawing colors, block size, live preview behaviour, metadata and the visible Excalidraw tools. The result is a tighter workflow for writing equations, sketching on top of them and keeping both the source and annotations together in the same note.

The Excalidraw CN plugin is an Obsidian tool that integrates the Excalidraw whiteboard with a default Chinese handwriting font. It allows users to create and annotate diagrams directly within Obsidian, with features like support for double links, Chinese handwriting, and advanced Excalidraw functionality. Users can easily link Obsidian notes and files within the Excalidraw canvas and use multiple canvas support. The plugin is designed for efficient visual note-taking and includes support for future enhancements such as custom fonts, mind maps, and cloud storage.

The Excalidraw Extras plugin is a companion package for the main Excalidraw plugin rather than a standalone tool. It pulls heavy dependencies and higher privilege operations out of the core package, including MathJax to SVG rendering, Mermaid conversion, PDF printing and APIs that need file system, network or Electron IPC access. That split keeps the main drawing plugin smaller and within stricter community security limits, while still letting advanced features load when they are actually needed.
