Relative permeability and capillary pressure
============================================

Plot saturation functions.

Append a SATNUM table number or ``h`` for hysteresis curves.

.. code-block:: console

   plopm -i H2HYSTERESIS -v krgh,krwh -llb 'Hydrogen  Brine' -c r,#0314fc -x '[0,1]' -lw 5 -fz 18 -fs 8,6 -yl 'Relative permeability, $k_r$ [-]' -xl 'Liquid saturation, $s_w$ [-]' -ls solid,solid -xnt 6 -ynt 6
   plopm -i H2HYSTERESIS -v pcwg -c k -x '[0,1]' -lw 5 -ll empty -fz 18 -fs 8,6 -yl 'Capillary pressure, $p_c$ [bar]' -xl 'Liquid saturation, $s_w$ [-]' -xnt 6 -ylog 1
