Graphing

Graphing is a simple graphing application for Linux.

Graphing supports the following functions:

Functions: sin, cos, tan, arcsin, arccos, arctan, floor, ceil, abs, max, min, sqrt, cbrt, ln, sum, prod
Operators: +, -, *, /, ^ (exponentiation), % (modulo)
Constants: pi, e

Installation

Graphing requires the development version of Owlkettle. Check out the installation instructions here.


        nimble install https://github.com/can-lehmann/Graphing

Building from source

Graphing is open-source. You can find the source code on GitHub.


        git clone https://github.com/can-lehmann/Graphing

        cd Graphing

        nimble build

Derivatives

Graphing can automatically compute derivatives of functions. The ' operator returns the derivative of the given function. Here we show the polynomial 1/5 (x - 1)(x + 2)(x - 3) and its derivative. The derivative is computed using (x -> 1/5 (x - 1)(x + 2)(x - 3))'(x).

Polar Plots

A polar plot is a plot that uses a polar coordinate system. It takes an angle as the input and maps it to a radius.

Export

You can export graphs as images by selecting "Export" in the main menu. The export dialog allows you to customize the graph before exporting.

Expressions of functions can be copied as LaTeX code. Click the copy button at the bottom of the function properties to copy its LaTeX source to your clipboard.
