I have a ValueError: year is out of range python for the below code for aiming to plot curve fit on time series.
Can anyone explain to me why I am getting this error?
x_values_formatted=[]
for i in x_values_edited:
x_values_formatted.append(time.mktime(i.timetuple()))
poly = np.polyfit(x_values_formatted, y_values, 3)
polynomial = np.poly1d(poly)
xs = np.linspace(np.min(x_values_formatted), np.max(x_values_formatted), len(x_values_formatted))
y_int = polynomial(xs)
plt.plot(x_values_edited, y_values, '.')
**plt.plot(xs, y_int)**
plt.show()
