      Signature: `ohlc(x, y, **kwargs)` or `ohlc(y, **kwargs)`, depending of the
      length of the list of positional arguments. In the case where the `x` array
      is not provided
  
      Parameters
      ----------
      x: numpy.ndarray or list, 1d (optional)
          The x-coordinates of the plotted line. When not provided, the function
          defaults to `numpy.arange(len(y))`.
      y: numpy.ndarray or list, 2d
          The ohlc (open/high/low/close) information. A two dimensional array. y
          must have the shape (n, 4).
      options: dict (default: {})
          Options for the scales to be created. If a scale labeled 'x' is
          required for that mark, options['x'] contains optional keyword
          arguments for the constructor of the corresponding scale type.
      axes_options: dict (default: {})
          Options for the axes to be created. If an axis labeled 'x' is required
          for that mark, axes_options['x'] contains optional keyword arguments
          for the constructor of the corresponding axis type.
