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

P-P plot of the percentiles (probabilities) of x versus the probabilities (percetiles) of a distribution.

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. fig – If ax is None, the created figure. Otherwise the figure to which ax is connected. Matplotlib figure instance
