          Args:
              nids: List of node identifiers.
              wslice: Slice object used to select works.
              kwargs: keyword arguments passed to `task.inspect` method.
  
          .. note::
  
              nids and wslice are mutually exclusive.
              If nids and wslice are both None, all tasks in self are inspected.
  
          Returns:
              List of `matplotlib` figures.
