# Ridgeline plot docstrings
_ridgeline_docstring = """
Create a {orientation} ridgeline plot (also known as a joyplot).

Ridgeline plots visualize distributions of multiple datasets as stacked,
overlapping density curves. They are useful for comparing distributions
across categories or over time.

Parameters
----------
data : list of array-like
    List of distributions to plot. Each element should be an array-like
    object containing the data points for one distribution.
labels : list of str, optional
    Labels for each distribution. If not provided, generates default labels.
positions : array-like, optional
    Y-coordinates for positioning each ridge. If provided, enables continuous
    (coordinate-based) positioning mode where ridges are anchored to specific
    numerical coordinates along the Y-axis. If None (default), uses categorical
    positioning with evenly-spaced ridges.
height : float or array-like, optional
    Height of each ridge in Y-axis units. Only used in continuous positioning mode
    (when positions is provided). Can be a single value applied to all ridges or
    an array of values (one per ridge). If None, defaults to the minimum spacing
    between positions divided by 2.
overlap : float, default: 0.5
    Amount of overlap between ridges, from 0 (no overlap) to 1 (full overlap).
    Higher values create more dramatic visual overlapping. Only used in categorical
    positioning mode (when positions is None).
kde_kw : dict, optional
    Keyword arguments passed to `scipy.stats.gaussian_kde`. Common parameters include:

    * ``bw_method`` : Bandwidth selection method (scalar, 'scott', 'silverman', or callable)
    * ``weights`` : Array of weights for each data point

    Only used when hist=False.
points : int, default: 200
    Number of evaluation points for KDE curves. Higher values create smoother
    curves but take longer to compute. Only used when hist=False.
hist : bool, default: False
    If True, uses histograms instead of kernel density estimation.
bins : int or sequence or str, default: 'auto'
    Bin specification for histograms. Can be an integer (number of bins),
    a sequence defining bin edges, or a string method ('auto', 'sturges', etc.).
    Only used when hist=True.
fill : bool, default: True
    Whether to fill the area under each density curve.
alpha : float, default: 0.7
    Transparency level for filled areas (0=transparent, 1=opaque).
linewidth : float, default: 1.5
    Width of the outline for each ridge.
edgecolor : color, default: 'black'
    Color of the ridge outlines.
facecolor : color or list of colors, optional
    Fill color(s) for the ridges. If a single color, applies to all ridges.
    If a list, must match the number of distributions. If None, uses the
    current color cycle or colormap.
cmap : str or Colormap, optional
    Colormap name or object to use for coloring ridges. Overridden by facecolor.

Returns
-------
list
    List of artist objects for each ridge (PolyCollection or Line2D).

Examples
--------
>>> import ultraplot as uplt
>>> import numpy as np
>>> fig, ax = uplt.subplots()
>>> data = [np.random.normal(i, 1, 1000) for i in range(5)]

>>> # With colormap
>>> fig, ax = uplt.subplots()
>>> ax.ridgeline(data, cmap='viridis', overlap=0.7)

>>> # With histograms instead of KDE
>>> fig, ax = uplt.subplots()
>>> ax.ridgeline(data, hist=True, bins=20)

_graph_docstring = r"""
Plot a networkx graph with flexible node, edge, and label options.

Parameters
----------
g : networkx.Graph
    The graph object to be plotted. Can be any subclass of :class:`~networkx.Graph`, such as
    :class:`~networkx.DiGraph` or :class:`~networkx.MultiGraph`.
layout : callable or dict, optional
    A layout function or a precomputed dict mapping nodes to 2D positions. If a function
    is given, it is called as ``layout(g, **layout_kw)`` to compute positions. See :func:`networkx.drawing.nx_pylab.draw` for more information.
nodes : bool or iterable, default: rc["graph.draw_nodes"]
    Which nodes to draw. If `True`, all nodes are drawn. If an iterable is provided, only
    the specified nodes are included. This effectively acts as `nodelist` in :func:`networkx.drawing.nx_pylab.draw_networkx_nodes`.
edges : bool or iterable, default: rc["graph.draw_edges"]
    Which edges to draw. If `True`, all edges are drawn. If an iterable of edge tuples is
    provided, only those edges are included. This effectively acts as `edgelist` in :func:`networkx.drawing.nx_pylab.draw_networkx_edges`.
labels : bool or iterable, default: `rc["graph.draw_labels`]
    Whether to show node labels. If `True`, labels are drawn using node names. If an
    iterable is given, only those nodes are labeled.
layout_kw : dict, default: {}
    Keyword arguments passed to the layout function, if `layout` is callable, see `networkx's drawing functions <https://networkx.org/documentation/stable/reference/drawing.html>`_ for more information.
node_kw : dict, default: {}
    Additional keyword arguments passed to the node drawing function (see :func:`networkx.drawing.nx_pylab.draw_networkx_nodes`). These can include
    size, color, edgecolor, cmap, alpha, etc., depending on the backend used, see :func:`networkx.drawing.nx_pylab.draw_networkx_nodes`.
edge_kw : dict, default: {}
    Additional keyword arguments passed to the edge drawing function. These can include
    width, color, style, alpha, arrows, etc (see :func:`networkx.drawing.nx_pylab.draw_networkx_edges`).
label_kw : dict, default: {}
    Additional keyword arguments passed to the label drawing function, such as font size,
    font color, background color, alignment, etc (see :func:`networkx.drawing.nx_pylab.draw_networkx_labels`).
rescale : bool,  None, default: None.
    When set to none it checks for `rc["graph.rescale"]` which defaults to `True`. This performs a rescale such that the node position is within a [0, 1] x [0, 1] box.
Returns
-------
Nodes, edges, labels output from the networkx drawing functions.

        Notes
        -----
        Special handling for plots from external packages (e.g., seaborn):

        When this method is used in a context where plots are generated by
        an external library like seaborn, it tags the resulting polygons
        (e.g., confidence intervals) as "synthetic". This is done unless a
        user explicitly provides a label.

        Synthetic artists are marked with `_ultraplot_synthetic=True` and given
        a label starting with an underscore (e.g., `_ultraplot_fill`). This
        prevents them from being automatically included in legends, keeping the
        legend clean and focused on user-specified elements.

        Seaborn internally generates tags like "y", "ymin", and "ymax" for
        vertical fills, and "x", "xmin", "xmax" for horizontal fills. UltraPlot
        recognizes these and treats them as synthetic unless a different label
        is provided.

            List of distributions to plot as ridges.
        labels : list of str, optional
            Labels for each distribution.
        positions : array-like, optional
            Y-coordinates for continuous positioning mode. If provided, ridges are
            anchored to these coordinates along the Y-axis.
        height : float or array-like, optional
            Height of each ridge in Y-axis units (continuous mode only).
        overlap : float, default: 0.5
            Amount of overlap between ridges (0-1). Higher values create more overlap.
            Only used in categorical mode.
        kde_kw : dict, optional
            Keyword arguments passed to `scipy.stats.gaussian_kde`. Common parameters:

            * ``bw_method`` : Bandwidth selection method
            * ``weights`` : Array of weights for each data point

            Only used when hist=False.
        points : int, default: 200
            Number of points to evaluate the KDE at. Higher values create smoother curves
            but take longer to compute. Only used when hist=False.
        hist : bool, default: False
            If True, use histograms instead of kernel density estimation.
        bins : int or sequence or str, default: 'auto'
            Bin specification for histograms. Passed to numpy.histogram.
            Only used when hist=True.
        histtype : {'fill', 'bar', 'step', 'stepfilled'}, optional
            Rendering style for histogram ridgelines. Defaults to ``'fill'``,
            which uses a filled ridge curve. ``'bar'`` draws histogram bars.
            Only used when hist=True.
        fill : bool, default: True
            Whether to fill the area under each curve.
        alpha : float, default: 1.0
            Transparency of filled areas.
        linewidth : float, default: 1.5
            Width of the ridge lines.
        edgecolor : color, default: 'black'
            Color of the ridge lines.
        facecolor : color or list of colors, optional
            Fill color(s). If None, uses current color cycle or colormap.
        cmap : str or Colormap, optional
            Colormap to use for coloring ridges.
        vert : bool, default: True
            If True, ridges are horizontal (traditional ridgeline plot).
            If False, ridges are vertical.
        **kwargs
            Additional keyword arguments passed to fill_between or fill_betweenx.

        Returns
        -------
        list
            List of PolyCollection objects for each ridge.
