Though yes, I still haven't documented the code. I hope you enjoy using it just as I enjoyed making it (I do use it myself too).Įven though I am the only one who worked on the code so far, I am open to work with others on it. My end goal is to make ZeGrapher the best on the features it offers (I am still far from that I know). It has been, and will be, a lot of fun thinking on how to code things, how to make it as easy to use as possible, to see things finally work. ZeGrapher is mainly a solo project and the fruit of years of discontinuous work on my free time. Chinese Culture University of Taipei: Through their Open Source Software Project, they translate ZeGrapher to Chinese (Traditional).Helmar Gerloni: Translates ZeGrapher and its website to German.Michael Bosch: Makes Archlinux packages.

Robert-André Mauchin: Makes Fedora packages.Georges Khaznadar: Makes Debian packages, and indirectly Ubuntu packages.Adel Kara Slimane: ZeGrapher's author and only developer, website maintainer.Here are few pictures that show what ZeGrapher looks like, and illustrate how it works. Plot the graph on an orthonormal basis.

Note that it will also affect rendering speed.

Change all the colors: axes, background, functions.

Zoom/unzoom on each axis separately, around the mouse (with the scroll wheel), or fit on a mouse drawn rectangle.

Select a curve to display the coordinates of its points.

Display a table of values with different options.

Export to all common image formats (png, jpeg, tiff, gif.).Choose the size and the position of the graph on the sheet.Plot tangents: they can be moved and resized simply with the mouse.Parametric plot for functions, sequences and parametric equations: the parameter symbol to use is 'k'.Data can be imported/exported from a CSV file. Experimental data plot and polynomial fit (regression).The curves can be animated, with adjustable framerate and speed. Numerical sequence plotting, they can be defined by a recurrent relation or explicitly.On a given function, others can be called, so it is possible to associate or compose functions. All the usual functions can be called: they're all written on a virtual keyboard. Visualize up to six functions simultaneously.It can plot functions, sequences, parametric equations and data on the plane.

An open source, free and easy to use math plotter.
