Graphing Calculator

Plot y = f(x) graphs — several functions at once, with zoom, pan and value readout. Free, no sign-up, and it runs in your browser — your files are never uploaded.

How to use

  1. Type functions of x, like x^2 - 4 or sin(x)
  2. Drag to move, scroll or use the buttons to zoom
  3. Hover to read values, then download the graph as PNG
