我正在使用以下代码。
%matplotlib notebook
plt.style.use('seaborn-bright')
fig,ax = plt.subplots(figsize=(8,6), facecolor='w', edgecolor='blue')
ax.spines['top'].set_visible(False)
ax.spines['bottom'].set_visible(False)
ax.spines['right'].set_visible(False)
ax.spines['left'].set_visible(False)
plt.title('Clubs of Severn Valley Petanque League - performance in years 2014-2019',color='purple',size=14.5,y=1.09)
ax.set_ylabel('Year', color='indigo',size=10)
ax.set_ylabel('Points won', color='darkblue', fontdict={'fontsize': 12, 'fontweight': 'medium'})
years=[2014,2015, 2016,2017,2018, 2019]
plt.xticks(np.arange(5), (years))
plt.margins(x=0.006,y=0.009)
ax.get_xaxis().tick_bottom()
ax.get_yaxis().tick_left()
ax.yaxis.set_major_formatter(plt.FuncFormatter('{:.0f}'.format))
ax.grid(True, 'major', 'y', ls='--', lw=.6, c='darkgray', alpha=.5)
ax.tick_params(axis='y', which='both', labelsize=10,bottom=False, top=False, labelbottom=True,
left=False, right=False, labelleft=True)
plt.legend(loc=2)
# Now I call each column( one for each team) one by one like so :
plt.plot(final.Points_Kinver.values, marker='o', label='Kinver Con Club')
plt.plot(final.Points_Nomads.values, marker='o', label='Nomads')
plt.plot(final.Points_TopPub.values, marker='o', label='Top Pub')
plt.plot(final.Points_Plough.values, marker='o', label='Plough')
plt.plot(final.Points_AlveleyRoyals.values, '-o', c='violet', label='Alveley Royals')
plt.plot(final.Points_Footloose.values, marker='o', c='yellow', label='Footloose')
plt.plot(final.Points_Gaters.values, '-o', c='orange', label="Gaters 'A'")
plt.plot(final.Points_AlveleyOaks.values, '-o',c='darkgreen', label='Alveley Oaks')
plt.show()
It works. Here is my chart 
.
但是，我希望我可以将plt.plot写成一行，但是这不起作用，给了我一个空白的图表。
plt.plot(final.columns.values, marker='o')
这会导致错误。

我也尝试过
final.plot( marker='o',ax=ax)
有用。但是，它删除了一些我精心编码的格式，更具体地说是刻度和网格线（ax.grid ...）。
您能解释一下为什么会在这里发生吗？
最好的方法是什么。我的下一步将是标记每行的末尾而不是图例，并且我所看到的代码包括df.columns。 所以我认为单行写会更好。
如您所见，我对matplotlib / python不太了解。我正在尝试通过为当地的地掷球协会创建可视化来进行练习。谢谢您对我的小项目的帮助。
