Python Plotting
===============
.. note::
Please see also the new project `CoolPlot <http://github.com/CoolProp/CoolPlot>`_, aiming to build upon the routines in CoolProp for plotting.
The simplest and most straight forward use case is the generation of plots
with default isolines and spacing. Here is a brief example to demonstrate
how to create a pressure-enthalpy (:math:`\log p,h`) plot for propane

You can also specify mixtures straight away and pass the mole fractions as part of the
fluid string.
.. plot::
:include-source:
from CoolProp.Plots import PropertyPlot
plot = PropertyPlot("REFPROP::ISOBUTAN[0.8]&PROPANE[0.2]", 'PH', unit_system='EUR', tp_limits='ACHP')
plot.calc_isolines()
plot.show()
If you would like to specify the mass fractions instead, you have to construct the state
object separately and pass it to the plot object instead of a string.
.. plot::
:include-source:
import CoolProp
state = CoolProp.AbstractState("REFPROP", "ISOBUTAN&PROPANE")
state.set_mass_fractions([0.8,0.2])
from CoolProp.Plots import PropertyPlot
plot = PropertyPlot(state, 'TS', unit_system='EUR', tp_limits='ACHP')
