Я пытаюсь построить 3 гистограммы в мультиплоте. Три файла данных:
Sta1.dat:
attn, mu2 , mu3, mu4
20, 4.9, 17.1, 78.1
25, 4.0, 22.0, 74.0
30, 2.0, 17.0, 81.0
35, 11.5, 21.7, 66.8
40, 4.7, 18.0, 77.4
45, 3.8, 8.9, 87.3
50, 0.6, 17.3, 82.1
55, 2.0, 3.4, 94.6
60, 1.0, 1.3, 97.6
Sta2.dat
attn, mu2 , mu3, mu4
20, 5.3, 20.6, 74.2

60, 1.7, 1.0, 97.3
Sta3.dat
attn, mu2 , mu3, mu4
20, 6.8, 20.6, 72.6
25, 6.2, 29.5, 64.3
30, 5.3, 23.6, 71.1
35, 4.5, 15.6, 79.9
40, 5.5, 17.4, 77.1

60, 1.0, 1.6, 97.4
В num.jpg столбцы гистограммы Station2 и Station3 выровнены, потому что отображаются легенды. На станции 1 я не указал легенду, и из-за этого столбцы гистограммы не выровнены.
Может ли кто-нибудь помочь получить корректировки в командах выровнять все бары.
