class_docstr: Displays an isocurve of a 2D scalar array.
  
  Parameters
  ----------
  data : ndarray | None
      2D scalar array.
  levels : ndarray, shape (Nlev,) | None
      The levels at which the isocurve is constructed from "*data*".
  color_lev : Color, colormap name, tuple, list or array
      The color to use when drawing the line. If a list is given, it
      must be of shape (Nlev), if an array is given, it must be of
      shape (Nlev, ...). and provide one color per level (rgba, colorname).
  clim : tuple
      (min, max) limits to apply when mapping level values through a
      colormap.
  **kwargs : dict
      Keyword arguments to pass to `LineVisual`.
