Free online graph plotter
This free graph plotter draws math functions on a coordinate grid with axes and labels. Type one or more functions of x — like x^2, sin(x) or 2x+1 — and each appears in its own color.
Zoom in and out to inspect details, and use the preset buttons to start from common examples. Perfect for homework and quick checks.
Frequently asked questions
What functions can I plot? Anything built from x, numbers, + - * / ^, brackets, and sin, cos, tan, sqrt, log, abs, plus pi and e.
Is my input executed as code? No. Input is checked against a strict whitelist first, and only allowed math is evaluated.
Why is part of a curve missing? Functions like log(x) or sqrt(x) are undefined for some x values — those stretches are simply skipped.
