Curve fitting with image draw of function graph

This C# ASP.NET page uses different curve fitting algorithms to find a mathematical function, y = f(x), for a set of x and y data points.

Note that some methods do not accept zero or negative numbers as x and/or y values.

The function y = f(x) may also be changed manually and compared with the data points.

See the page FunctionGraph for help and notes about mathematical expressions, syntaxes and graph tool buttons.

Clicking any OK button will save the inputs in the current session, until the web browser is closed.

No third-party add-ons or softwares are used on this page, only plain HTML with an image is used.
