Description Deniz Akcal 2009-06-20 05:33:10 UTC 
Version:           1.2.1 (using 4.2.2 (KDE 4.2.2), Debian packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.26-2-amd64

Circles, Ellipses, horizontal parabolas, and other non-function rules that can be plotted should be possible to plot! In addition to this, step functions (=greatest integer functions) are FUNCTIONS but they cannot be plotted. I don't know why this is exactly but my tutor's graphing calculator cannot plot step functions either while this other student's graphing calculator can! I don't have a graphing calculator and even if I did, I rely excessively on kmplot for learning the effects of the parameters in rules. I know for example circles can be split into two functions and when you plot both, you get a circle, however this should not be required.

So please add support for such things! Additionally, I would like to thank the developpers for their hard work thus far!

This is totally possible today. Learn to use Implicit Plots.

I think this can be closed.
