what am I doing wrong?
我究竟做错了什么？
import matplotlib.pyplot as plt
plt.rcParams['text.usetex'] = False
from matplotlib.font_manager import FontProperties
import seaborn as sns
%matplotlib inline
df1=df['Total Acc'].round(4)*100
labels = ['AWA','Rem', 'S1', 'S2', 'SWS', 'SX', 'ALL']
rows = [df1.loc[label] for label in labels]
for row in rows:
row.plot(figsize=(10, 5), marker='o')
# http://matplotlib.org/api/legend_api.html ---set_bbox_to_anchor(bbox, transform=None)
myLegend=plt.legend(labels, bbox_to_anchor=(0., 1.15, 1., .102), prop ={'size':10}, loc=10, ncol=7, #left, bottom, width, height
title=r'LEARNING CURVE - Fp1_RF(20)')
myLegend.get_title().set_fontsize('18')
plt.ylim(97.5, 98.5)
plt.xlim(0, 45)
plt.xlabel('# of samples per subject')
plt.ylabel('Accuracy')

If your matplotlib figure is getting trimmed, you can use Tight Layout. Details provided here
如果您的 matplotlib 图被修剪，您可以使用Tight Layout. 此处提供详细信息
In your code, try adding
在您的代码中，尝试添加
plt.tight_layout()
Another option that you can try is to use subplots_adjust(). Basically it provides you control over the default spacing on the left, right, bottom, and top as well as the horizontal and vertical spacing between multiple rows and columns. Sample Example here
您可以尝试的另一个选项是使用subplots_adjust(). 基本上，它可以让您控制左侧、右侧、底部和顶部的默认间距以及多行和多列之间的水平和垂直间距。示例示例在这里
plt.subplots_adjust(left=0.5, right=0.5)
