ProbPlot.
qqplot
(xlabel=None, ylabel=None, line=None, other=None, ax=None, **plotkwargs)[source]¶ QQ plot of the quantiles of x versus the quantiles/ppf of a distribution or the quantiles of another ProbPlot instance.
Parameters:  ylabel (xlabel,) – Userprovided lables for the xaxis and yaxis. If None (default), other values are used depending on the status of the kwarg other.
 line (str {'45', 's', 'r', q'} or None, optional) –
Options for the reference line to which the data is compared:
 ‘45’  45degree line
 ’s‘  standardized line, the expected order statistics are scaled by the standard deviation of the given sample and have the mean added to them
 ’r’  A regression line is fit
 ’q’  A line is fit through the quartiles.
 None  by default no reference line is added to the plot.
 other (ProbPlot instance, arraylike, or None, optional) – If provided, the sample quantiles of this ProbPlot instance are plotted against the sample quantiles of the other ProbPlot instance. If an arraylike object is provided, it will be turned into a ProbPlot instance using default parameters. If not provided (default), the theoretical quantiles are used.
 ax (Matplotlib AxesSubplot instance, optional) – If given, this subplot is used to plot in instead of a new figure being created.
 **plotkwargs (additional matplotlib arguments to be passed to the) – plot command.
Returns: fig – If ax is None, the created figure. Otherwise the figure to which ax is connected.
Return type: Matplotlib figure instance
