ProbPlot.qqplot(xlabel=None, ylabel=None, line=None, other=None, ax=None, **plotkwargs) [source]

Q-Q plot of the quantiles of x versus the quantiles/ppf of a distribution or the quantiles of another ProbPlot instance.

Parameters:	ylabel (xlabel,) – User-provided lables for the x-axis and y-axis. 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’ - 45-degree 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, array-like, 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 array-like 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
