How to put legend outside the plot with pandas
提问by user977828
How is it possible to put legend outside the plot?
怎么可能把传说放在情节之外？
import pandas as pd
import matplotlib.pyplot as plt
a = {'Test1': {1: 21867186, 4: 20145576, 10: 18018537},
'Test2': {1: 23256313, 4: 21668216, 10: 19795367}}
d = pd.DataFrame(a).T
#print d
f = plt.figure()
plt.title('Title here!', color='black')
plt.legend(loc='center left', bbox_to_anchor=(1, 0.5))
d.plot(kind='bar', ax=f.gca())
plt.show()

I think you need to call plotbefore you add the calling legend.
我认为你需要plot在添加调用之前调用legend。
import pandas as pd
import matplotlib.pyplot as plt
a = {'Test1': {1: 21867186, 4: 20145576, 10: 18018537},
'Test2': {1: 23256313, 4: 21668216, 10: 19795367}}
d = pd.DataFrame(a).T
#print d
f = plt.figure()
plt.title('Title here!', color='black')
d.plot(kind='bar', ax=f.gca())
plt.legend(loc='center left', bbox_to_anchor=(1.0, 0.5))
plt.show()
----- Panda solution If you are using pandas Dataframe.plot
----- Panda 解决方案 如果你使用的是pandas Dataframe.plot
dataframe_var.plot.bar().legend(loc='center left',bbox_to_anchor=(1.0, 0.5));
