2D Plotter Calculator

Plot one or more functions with adjustable ranges, equal scaling, and shared sessions.

Plot multiple functions at once. Enter f(x) or y = f(x) for standard curves, and x = g(y) or bare g(y) for sideways curves.

2D Plot Help

1. Enter one curve per line: use f(x) or y = f(x) for standard plots, and x = g(y) or bare g(y) for sideways plots.

2. Use mouse wheel to zoom.

3. Hold Shift for x-axis zoom only.

4. Hold Alt/Option for y-axis zoom only.

5. Enable Equal units for true geometric proportions.
