Hi
I would add data (gcmcdata) to existing plot
When I run code below

from cProfile import label
import pandas as pd
import matplotlib.pyplot as plt
import os

path = r"C:\Users\Alberto\OneDrive - ELEVA\Documenti\CHAMELEON\Pyton\plot\results_CH4_298K\METHANE_298K_MORSE_5-100.0_bar"
os.chdir(path)

# take data
gcmcdata = pd.read_csv('gcmc_results_CH4_298K_0-100Bar.log', sep=' ')
gcmcdatalj = pd.read_csv('gcmc_results_LJ_CH4_298K_0-100Bar.log', sep=' ')
expdata = pd.read_csv('methane_298K_0-100bar_exp.txt', skiprows=1, sep='\t')

ax = gcmcdata.plot(x='Press [bar]', y='Density [mol/L]', color='green', linestyle='dashed', marker='o', label='MORSE')
ax = gcmcdatalj.plot(x='Press [bar]', y='Density [mol/L]', color='red', linestyle='dashed', marker='o', label='LJ')
expdata.plot(ax=ax, x=1, y=2, color='blue', linestyle='dashed', marker='o', label='experimental')

#print(expdata)

plt.title('Methane - 298 K')
plt.axis([None, None, 0, 6])
plt.xlabel('Press [bar]')
plt.ylabel('Density [mol/L]')
plt.legend(loc='lower right')
plt.grid()
plt.show()

I odtain two different plots and not one
One plot with "LJ" and 'experimental', and one only with 'morse'
How could fix it?

Regards
