大 pandas 重建人物传说 [英] reconstruction figure legend in pandas

问题描述

在绘制图形后，我得到一个图形图例，如下所示:

after plotting a figure I get a figure legend as below:

DataFrame1.plot(legend=False)
patch,labels=ax.get_legend_handels_labels()
DateFrame1.legend(loc='best')
plt.show()

如何删除(Temp，2005)中的'Temp'，让它变成2005年?

How can I delete the 'Temp' in (Temp,2005) ,let become just 2005?

DataFrame1具有三个键:月，年，温度.

the DataFrame1 has three keys:Month,Year,Temp.

推荐答案

您非常亲密，您只需要更新年份的图例即可:

You were very close, you just need to update your legend with the years:

ax = df.plot()

years = [2005, 2007, 2008, 2009, 2011, 2012]
# you can get years from you dataframe (but without seeing the dataframe I can't say exactly how)
# legend also accepts a Series or numpy array
ax.legend(years, loc='best')
plt.show()
