python画图，为什么x，y轴会和图分开？

import numpy as np
import pandas as pd
from matplotlib.ticker import MultipleLocator, FormatStrFormatter
import matplotlib.pyplot as plt
from matplotlib.lines import Line2D

plt.rcParams['font.sans-serif']=['SimHei'] #用来正常显示中文标签

plt.title('样本1')
plt.xlabel('波数')
plt.ylabel('吸光度')
xmajorLocator = MultipleLocator(500)
xmajorFormatter = FormatStrFormatter('%1f')
xminorLocator = MultipleLocator(1)
ymajorLocator = MultipleLocator(0.05)
ymajorFormatter = FormatStrFormatter('%1f')
yminorLocator = MultipleLocator(0.001)
plt.xlim([650,4000])
plt.ylim([-0.06,0.95])

plot1=dt2.plot(linewidth=0.5)#dt2是要画的图的数据
plot1.legend_.remove()

不是图例的错误，关于图例的错误已解决

我也是这个问题，后来我把调整刻度挪到画图后面就好了
