我想在yticklabel小数点分隔符上从小数点更改为逗号，但是在使用 .

I want to change on the yticklabel decimal separator from a decimal point to a comma, but leave the format of the offset text (1e-14), after using code from this code or that code.

1. 如何将点更改为逗号并保存1e-14?
2. 如何在偏移文本中将e更改为E?

1. How can I change the point to a comma and save 1e-14?

要将小数点分隔符从点更改为逗号，可以更改

To change the decimal separator from a point to a comma, you can change the locale to somewhere where a comma is used. For example, here I set it to German:

#Locale settings
import locale
# Set to German locale to get comma decimal separater
locale.setlocale(locale.LC_NUMERIC, "de_DE")

import numpy as np
import matplotlib.pyplot as plt
plt.rcdefaults()

# Tell matplotlib to use the locale we set above
plt.rcParams['axes.formatter.use_locale'] = True

# make the figure and axes
fig,ax = plt.subplots(1)

# Some example data
x=np.arange(100)
y=4e-18*x**2

# plot the data
ax.plot(x,y,'b-')

plt.show()

将偏移量文本中的指数更改为E似乎不是一个简单的任务.您可能会在此处.

Changing the exponent to E in the offset text does not seem to be a simple task. You might start by looking at the answers here.
