The Function Plot plugin enables users to create and display mathematical graphs within Obsidian. It provides a graphical interface for plotting functions with a live preview feature, allowing users to adjust graph settings interactively. Users can also define custom plots through dedicated code blocks, specifying graph titles, labels, bounds, and more. The plugin supports a wide range of mathematical functions, offering flexibility for complex graphing needs. Customization options are available via a settings page, including font sizes, line widths, and color adjustments. The plugin is ideal for visualizing mathematical data or concepts directly in notes, enhancing the analytical and educational capabilities of Obsidian.
