(event)
Get information for a pick event on a PathCollection artist (usually

    Parameters
    -----------
    event : PickEvent
        The pick event to process

    Returns
    --------
    A dict with keys:
        `c`: The value of the color array at the point clicked.
        `s`: The value of the size array at the point clicked.
        `z`: Identical to `c`. Specified for convenience.

    Notes
    -----
    If constant values were specified to ``c`` or ``s`` when calling
    ``scatter``, `c` and/or `z` will be ``None``.
