Function Graphing Pad
Plot up to six math functions together. Change values and graph ranges, zoom in and download the chart.
How can I compare several functions with adjustable parameters?
Enter one expression per line using x and the parameters a, b and c. Set the parameter values, domain and sampling resolution, then plot the curves together. Zoom and inspect coordinates, and export a chart or a reusable project.
Your data, clearly.
On your deviceLimits: six formulas, 2,000 samples per formula and parameter/domain magnitudes up to 1,000,000.
Use x, a, b and c with + − * / ^, sin, cos, tan, sqrt, log and other supported math functions. Adjust a parameter and draw again.
A little data. A clearer picture.
Choose your data and settings, then draw the chart to explore the details.

What are the limits and details?
Curves use bounded numerical sampling, not symbolic proofs. Undefined or very large values become gaps. Sampling can miss discontinuities or rapid changes; adjust the domain and resolution and review the plotted values.
Limits: six formulas, 2,000 samples per formula and parameter/domain magnitudes up to 1,000,000.
