-Plotting
-========
-
-ctools and GammaLib do not include classes and scripts to make plots.
-
-This is intentional because creating and maintaining plotting tools that work
-on all platforms and cover all needs is a big project in itself, and deciding
-to support a plotting package that is popular now as part of the CTA science
-tools could become very problematic in the future.
-
-But we realise that most ctools users need to create plots for their high-level
-science results, so on this page we provide a few pointers to external packages
-and tools.
-
-Nevertheless, for your convenience several scripts for graphical display are
-included in the ctools package that rely on the
-`matplotlib <http://matplotlib.org>`_
-Python module. You can find these scripts in the
-``$CTOOLS/share/examples/python`` folder. The following scripts are available:
-
-  +------------------------+-----------------------------+
-  | Script                 | Usage                       |
-  +========================+=============================+
-  | ``show_butterfly.py``  | Display a butterfly diagram |
-  +------------------------+-----------------------------+
-  | ``show_lightcurve.py`` | Display a light curve       |
-  +------------------------+-----------------------------+
-  | ``show_obs.py``        | Display observation summary |
-  +------------------------+-----------------------------+
-  | ``show_pointings.py``  | Display pointing directions |
-  +------------------------+-----------------------------+
-  | ``show_phases.py``     | Display event phases        |
-  +------------------------+-----------------------------+
-  | ``show_spectrum.py``   | Display a spectrum          |
-  +------------------------+-----------------------------+

-Below some usage examples and the expected output.
