Obsidian plugins with #plotting#

The Mathpad plugin enhances your Obsidian experience by integrating a powerful calculator and plotting system. Based on Nerdamer for symbolic and numeric calculations, and function-plot for 2D plotting, Mathpad offers a sidebar, code block, and inline block features. The sidebar functions as a stand-alone calculator, capable of providing dynamic code blocks or static LaTeX results that can be inserted into your notes. It also allows the inclusion of computations and plots directly within notes through code blocks and inline code.

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.
