Intended to be called only by __new__. mode_arg Can be a string or a class. If it is a PlotMode subclass, it is simply returned. If it is a string, it can an alias for a mode or an empty string. In the latter case, we try to find a default mode for the i_var_count and d_var_count. i_var_count The number of independent variables needed to evaluate the d_vars. d_var_count The number of dependent variables; usually the number of functions to be evaluated in plotting. For example, a Cartesian function y = f(x) has one i_var (x) and one d_var (y). A parametric form x,y,z = f(u,v), f(u,v), f(u,v) has two two i_vars (u,v) and three d_vars (x,y,z). sETo use unregistered plot mode %s you must first call %s._init_mode().s7%s can only plot functions with %i dependent variables.sA%s cannot plot functions with more than %i independent variables.s-PlotMode argument must be a class or a stringN(tNonet issubclassR t TypeErrort_was_initializedt ValueErrort__name__t d_var_countt i_var_countt isinstanceRt _i_var_maxtvar_count_errortTruet _d_var_maxtFalset_get_default_modet_get_aliased_mode(R#R1R0tmR&R'((sBlib/python2.7/site-packages/sympy/plotting/pygletplot/plot_mode.pyR[s:     iÿÿÿÿcC s||dkr|}nytj||SWnMtk rw|tjkr^tj|d||ƒStd||fƒ‚nXdS(NiÿÿÿÿisKCouldn't find a default mode for %i independent and %i dependent variables.(R t_mode_default_maptKeyErrorR3R8R.(R&R'R%((sBlib/python2.7/site-packages/sympy/plotting/pygletplot/plot_mode.pyR8¥s   cC sº|dkr|}n|tjkrItd|djtjƒfƒ‚nytj|||SWnStk rµ|tjkr™tj||d||ƒStd|||fƒ‚nXdS(Niÿÿÿÿs0Couldn't find a mode called %s.
