fplot@t-st.de by Thomas Steinfeld

Fplot is the easy to use but universal function plotter. It plots functions in the form y=f(x) or in the implicit form f(x,y)=0. You may display up to 10 functions simultaneously; zoom and pan them even during redraw. You can change the plot colors and preview the plots on the fly. The program supports a sophisticated set of functions.
