洛伦兹安装不够好

Question

洛伦兹情节拟合的合适问题。在OriginPro上，它非常合适。

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
from lmfit.models import LorentzianModel
import numpy as np


datas = pd.read_csv('pg60_02_0.5V.csv')
a = datas.to_numpy()
a = a.transpose()
x= a[0]
y= a[1]

model = LorentzianModel()
pars = model.guess(y, x=x)
out = model.fit(y, pars, x=x)
print(out.fit_report())
plt.plot(x, y)
plt.plot(x, out.best_fit, '-', label='best fit')
plt.legend()
plt.show()

这是 plot 。
