. This cycle defaults to :rc:`axes.prop_cycle`.

        marker : `~.markers.MarkerStyle`, default: :rc:`scatter.marker`
            The marker style. *marker* can be either an instance of the class
            or the text shorthand for a particular marker.
            See :mod:`matplotlib.markers` for more information about marker
            styles.

        %(cmap_doc)s

            This parameter is ignored if *c* is RGB(A).

        %(norm_doc)s

            This parameter is ignored if *c* is RGB(A).

        %(vmin_vmax_doc)s

            This parameter is ignored if *c* is RGB(A).

        alpha : float, default: None
            The alpha blending value, between 0 (transparent) and 1 (opaque).

        linewidths : float or array-like, default: :rc:`lines.linewidth`
            The linewidth of the marker edges. Note: The default *edgecolors*
            is 'face'. You may want to change this as well.

        edgecolors : {'face', 'none', *None*} or color or sequence of color, default: :rc:`scatter.edgecolors`
            The edge color of the marker. Possible values:

            - 'face': The edge color will always be the same as the face color.
            - 'none': No patch boundary will be drawn.
            - A color or sequence of colors.

            For non-filled markers, *edgecolors* is ignored. Instead, the color
            is determined like with 'face', i.e. from *c*, *colors*, or
            *facecolors*.

        plotnonfinite : bool, default: False
            Whether to plot points with nonfinite *c* (i.e. ``inf``, ``-inf``
            or ``nan``). If ``True`` the points are drawn with the *bad*
            colormap color (see `.Colormap.set_bad`).

        Returns
        -------
        `~matplotlib.collections.PathCollection`

        Other Parameters
        ----------------
        data : indexable object, optional
            DATA_PARAMETER_PLACEHOLDER
        **kwargs : `~matplotlib.collections.Collection` properties

        See Also
        --------
        plot : To plot scatter plots when markers are identical in size and
            color.

        Notes
        -----
        * The `.plot` function will be faster for scatterplots where markers
          don't vary in size or color.

        * Any or all of *x*, *y*, *s*, and *c* may be masked arrays, in which
          case all masks will be combined and only unmasked points will be
          plotted.

        * Fundamentally, scatter works with 1D arrays; *x*, *y*, *s*, and *c*
          may be input as N-D arrays, but within scatter they will be
          flattened. The exception is *c*, which will be flattened only if its
          size matches the size of *x* and *y*.
