Problem with iso-enthalps
@ibell @jowr please can you help me debug the following sample code, I'm not sure if the error I am getting is due to the code changes I made in the plotting package or due to something else.
from CoolProp.Plots import PropsPlot
plt = PropsPlot('R600a', 'Ts')
plt.draw_isolines('H', [100, 300], num=5)
plt.show()
The error I get is
ValueError: CoolProp error: Inputs in Brent [113,730000,392,481449] do not bracket the root. Function values are [268331,802491,586497,269690] :: inputs were:"T",'H',1.0000000000000000e+02,'S',-5.2671895957182779e-01,"R600a"
Are you close to the critical point? Sometimes the h-s solver fails quite close to the critical point...

I'll look at bit more closely at this tomorrow again.
