Save histograms
^^^^^^^^^^^^^^^

as text files.

Load data
^^^^^^^^^

You can either load data from a text or a `ROOT <https://root.cern.ch/>`_ file.
You can either load it as a histogram, i.e., as an instance of :class:`.Hist1D` 
or :class:`.Hist2d`, or as NumPy :class:`numpy.ndarray`.

When loading 2D data as ``ndarray``, they are wrapped in a
:class:`.PcolormeshData` (or :class:`.ImshowData`). These are basically
wrapper functions providing some convenience. See documentation of 
:func:`.load_2d_from_txt` and :func:`.load_2d_from_root` for more information.
