Generally, users can provide the following arguments to a plot function: expr, range1 [tuple, opt], ..., label [str, opt], rendering_kw [dict, opt] `expr, range1, ...` can be sympified, whereas `label, rendering_kw` can't. In particular, whenever a special character like $, {, }, ... is used in the `label`, sympify will raise an error. r FVector)r"rr# enumerater$r _plot_sympifystrdictr __class____name__rr )argsias rr=r=6s$ ::D$ ! !1 a$ ' ' !]1--=u==DGGQd ,, !  ! %11:a;O;O1ajjDG KrNcd}t|}|'||}t||krIt dd|zdt||zt||kr"t dt|d|t d|D}t|t|krt d t||kr||}|t kr#|D] } ||| !t|t|z D],} ||t-t||krt d |D}t||d kr;t d d |zd|z|S)aThis function does two things: 1. Check if the number of free symbols is in agreement with the type of plot chosen. For example, plot() requires 1 free symbol; plot3d() requires 2 free symbols. 2. Sometime users create plots without providing ranges for the variables. Here we create the necessary ranges. Parameters ========== exprs : iterable The expressions from which to extract the free symbols ranges : iterable The limiting ranges provided by the user npar : int The number of free symbols required by the plot functions. For example, npar=1 for plot, npar=2 for plot3d, ... params : dict A dictionary mapping symbols to parameters for interactive plot. c$t|ddS)Nir+r)symbols rz _create_ranges..lsuVS"'='=rNzToo many free symbols. zExpected {} free symbols. zReceived {}: {}zToo many ranges.

Parameters ========== args The arguments provided to the plot functions nexpr The number of sub-expression forming an expression to be plotted. For example: nexpr=1 for plot. nexpr=2 for plot_parametric: a curve is represented by a tuple of two elements. nexpr=1 for plot3d. nexpr=3 for plot3d_parametric_line: a curve is represented by a tuple of three elements. npar The number of free symbols required by the plot functions. For example, npar=1 for plot, npar=2 for plot3d, ... **kwargs : keyword arguments passed to the plotting function. It will be used to verify if ``params`` has ben provided.
