Rust Function Plotter

CLI program written in Rust that parses a mathematical function of x and renders its graph to an image file.

What it does

• reads function from CLI argument
• samples function over a numeric range
• renders 2D plot to image (e.g. PNG)
• no GUI, no server, just a binary

Requirements

• Rust (stable)
• cargo

Build

git clone https://github.com/TygrysGracz/rust-function-plotter
cd rust-function-plotter
cargo build --release

Run cargo run --release -- "sin(x)" output.png

Function syntax, sampling, and output

Function syntax

• variable: x
• operators: + - * / ^
• parentheses supported
• typical math functions: sin, cos, tan, log, exp (depends on parser implementation)

Sampling and range

• default X range is hardcoded (check main.rs)
• step size controls smoothness and performance
• edit constants in code to change resolution or bounds

Output

• image is written to the path given as the second argument
• existing file will be overwritten
