You can specify a coordinate mode explicitly with the 'mode' named argument, but it can be automatically determined for Cartesian or parametric plots, and therefore must only be specified for polar, cylindrical, and spherical modes. Specifically, Plot(function arguments) and Plot[n] = (function arguments) will interpret your arguments as a Cartesian plot if you provide one function and a parametric plot if you provide two or three functions. Similarly, the arguments will be interpreted as a curve if one variable is used, and a surface if two are used. Supported mode names by number of variables: 1: parametric, cartesian, polar 2: parametric, cartesian, cylindrical = polar, spherical >>> Plot(1, mode='spherical') Calculator-like Interface ========================= >>> p = Plot(visible=False) >>> f = x**2 >>> p[1] = f >>> p[2] = f.diff(x) >>> p[3] = f.diff(x).diff(x) >>> p [1]: x**2, 'mode=cartesian' [2]: 2*x, 'mode=cartesian' [3]: 2, 'mode=cartesian' >>> p.show() >>> p.clear() >>> p >>> p[1] = x**2+y**2 >>> p[1].style = 'solid' >>> p[2] = -x**2-y**2 >>> p[2].style = 'wireframe' >>> p[1].color = z, (0.4,0.4,0.9), (0.9,0.4,0.4) >>> p[1].style = 'both' >>> p[2].style = 'both' >>> p.close() Plot Window Keyboard Controls ============================= Screen Rotation: X,Y axis Arrow Keys, A,S,D,W, Numpad 4,6,8,2 Z axis Q,E, Numpad 7,9 Model Rotation: Z axis Z,C, Numpad 1,3 Zoom: R,F, PgUp,PgDn, Numpad +,- Reset Camera: X, Numpad 5 Camera Presets: XY F1 XZ F2 YZ F3 Perspective F4 Sensitivity Modifier: SHIFT Axes Toggle: Visible F5 Colors F6 Close Window: ESCAPE ============================= rrc|SSKJn X lSUl[ 5Ul0Ul/Ul[U5Ul [URSS55n[S 0UD6Ul URRUR5 XS'URSS5(aUR!5 gg) aY Positional Arguments ==================== Any given positional arguments are used to initialize a plot function at index 1. In other words... >>> from sympy.plotting.pygletplot import PygletPlot as Plot >>> from sympy.abc import x >>> p = Plot(x**2, visible=False) ...is equivalent to... >>> p = Plot(visible=False) >>> p[1] = x**2 Note that in earlier versions of the plotting module, you were able to specify multiple functions in the initializer. This functionality has been dropped in favor of better automatic plot plot_mode detection.
