我從3個不同的數據框(全部使用相同的鍵)導入數據,並將它們放在一起以形成單個數據框。使用pd.DataFrame中的MultiIndex繪製數據
df1 = read_xlsx('Means_Cent')
df2 = read_xlsx('Means_Rand')
df3 = read_xlsx('Means_Const')
df1['Key'] = 'Cent'
df2['Key'] = 'Rand'
df3['Key'] = 'Const'
df_means = pd.concat([df1,df2,df3], keys = ['Cent', 'Rand', 'Const'])
現在我想創建使用DataFrame.plot()其中,I 1個具有圖表爲每個鍵=曲線[「美分」,「蘭德」,「CONST」〕中相同的數字。我的數據框df_means的
部分看起來是這樣的:
02_VOI 03_Solidity 04_Total_Cells
Cent 0 1.430 19.470 132.0
1 1.415 18.880 131.0
2 1.460 19.695 135.0
3 1.520 19.695 141.0
Rand 0 1.430 19.205 132.0
1 1.430 19.170 132.0
2 1.445 19.430 133.5
3 1.560 19.820 144.5
Const 0 1.175 22.695 108.5
1 1.430 22.260 132.0
2 1.180 21.090 109.0
3 1.360 22.145 126.0
現在我要繪製02_VOI VS 04_Total_Cells,它應該是1個圖中每個鍵(G1 = 02_VOI(分)VS 04_Total_Cells(分) ,G2 = 02_VOI(RAND)VS 04_Total_Cells(RAND)...)
我嘗試使用DataFrame.unstack():
df_means.unstack(level = 0).plot(x = '02_VOI', y = '04_Total_Cells')
但這似乎陷入困境的鑰匙。它會返回9個圖表(每個VOI(Cent,Rand,Const)和Total_Cells(Cent,Rand,Const)組合的1個組合)。 3個初始dataframes
