pandas畫圖

Serise上的畫圖

import matplotlib.pyplot as plt
import pandas as pd
from pandas import *
import numpy as np
s = Series(np.random.rand(10).cumsum(),index=np.arange(0,100,10))
s.plot()
plt.show()

DataFrame畫圖相當爽 看看

import matplotlib.pyplot as plt
import pandas as pd
from pandas import *
import numpy as np
df = pd.DataFrame(np.random.rand(10,4),columns=[‘A’,’B’,’C’,’D’],index=np.arange(0,100,10))
print(df)
df.plot()
plt.show()

畫柱狀圖

import matplotlib.pyplot as plt
import pandas as pd
from pandas import *
import numpy as np
fig,axes = plt.subplots(2,1)
data = Series(np.random.rand(16),index=list(‘abcdefghijklmnop’))
data.plot(kind = ‘bar’,ax = axes[0],color = ‘k’,alpha = 0.7)
data.plot(kind = ‘barh’,ax = axes[1],color = ‘k’,alpha = 0.7)
plt.show()

import matplotlib.pyplot as plt
import pandas as pd
from pandas import *
import numpy as np
df = pd.DataFrame(np.random.rand(6,4),index=[‘one’,’two’,’three’,’four’,’five’,’six’],
columns=pd.Index([‘A’,’B’,’C’,’D’],name = ‘Genus’))
print(df)
df.plot(kind = ‘bar’,stacked = True)
plt.show()
