specify line plot color

Hi alberto,

If I have correctly understood your wish, you may be looking for in

This may not be really Matplotlib's field anymore, but please find
attached a small example on how to record data into a flat text file and
reload them. Hopefully this will helpful to you.

Best regards,

I wrote days ago about script python
I would ask you if exist a way to print in a file the data of a plot

this is my script

#!/usr/bin/env python

import numpy as np
import matplotlib.pyplot as plt
import sys

# Temperature that we are interested in
target_T = 10.0
#%% Load all condtens data
data = np.loadtxt("Pb8I28-MA-BISIMID_101010Kp_FR.condtens")
#%% Load trace data
data2 = np.loadtxt("Pb8I28-MA-BISIMID_101010Kp_FR.trace")
# Select only the data points computed at that specific temperature
T = data[:, 1]
indices = (T == target_T)

#%%Fermi levels converted in electronvolts
Ef = 13.60 * data[indices, 0]

#%% plot trace at T
Fermi_level = 4.44075 # (in eV)

labels = ("$\sigma$ / $tau$",)
for i, label in enumerate(labels):
??? plt.plot((Ef - Fermi_level), data2[indices,(abs(5))], label=label)
plt.xlabel(r"Energy-Efermi [eV]")
plt.ylabel(r"$\sigma$/$\tau$ [$\Omega$ m s]")

#%% plot DOS(Ef) at T

au_to_m = 5.291772083E-11
V = 7670.7134 # a.u.^3
m_el = 9.10938356E-31 #Kg
V_m3 = V*(au_to_m)**3

labels = ("DOS",)
for i, label in enumerate(labels):
??? plt.plot(Ef, data2[indices,(3)], label=label)
plt.xlabel(r"Ef [eV]")
plt.ylabel(r"n /($\mu)$ [e / m^3]")

# And recast as an array of 3x3 matrices for convenience
# Column numbers are easy to follow: 1 for Ef, 1 for T, 1 for N, 9 for
# and then comes the Seebeck coefficient
sigma = data[indices, 3:12].reshape((-1, 3, 3))
seebeck = data[indices, 12:21].reshape((-1, 3, 3))

# Plot the xx, yy and zz components as a function of the first column
labels = ("xx", "yy", "zz")
for i, label in enumerate(labels):
??? plt.plot(Ef, sigma[:, i, i], label=label)
plt.xlabel(r"Energy [eV]")
plt.ylabel(r"$\sigma$ [1/$\Omega$ m s]")

in particular I would write four columns with ef and xx yy zz in a

        Hi Alberto,

        I now understand better. No need to flip you data then: you can
        actually explicitly specify the color that? you want in the
        `plot` function, with the *color* keyword argument. See the
        attached script that should hopefully help you to get what you want.

        Best regards,

            Hi vincet,

            in my plot (see .png file)

            I would invert the color

            xx --> green
            zz--> blue
