pylab条形图查询

我相对较新的绘图pylab中，这里是一个问题。我有一个包含长度范围从2到10的单词的文本文件，现在我的任务是使用条形图来绘制每个单词类别的频率。我能写剧本并绘制它，但xtick标签搞砸了，我想知道这是什么原因。在此先感谢您的帮助。pylab条形图查询

two_letter=[] 
three_letter=[] 
four_letter=[] 
five_letter=[] 
six_letter=[] 
seven_letter=[] 
eight_letter=[] 
nine_letter=[] 
ten_letter=[] 

inFile = open('words.txt') 
for line in inFile.readlines(): 
    fields = line.split(' ') 
    for word in fields: 
     if len(word) == 2: 
      two_letter.append(word) 
     elif len(word) == 3: 
      three_letter.append(word) 
     elif len(word) == 4: 
      four_letter.append(word) 
     elif len(word) == 5: 
      five_letter.append(word) 
     elif len(word) == 6: 
      six_letter.append(word) 
     elif len(word) == 7: 
      seven_letter.append(word) 
     elif len(word) == 8: 
      eight_letter.append(word) 
     elif len(word) == 9: 
      nine_letter.append(word) 
     else: 
      len(word) == 10 
      ten_letter.append(word) 
two_l = len(two_letter) 
three_l = len(three_letter) 
four_l = len(four_letter) 
five_l = len(five_letter) 
six_l = len(six_letter) 
seven_l = len(seven_letter) 
eight_l = len(eight_letter) 
nine_l = len(nine_letter) 
ten_l = len(ten_letter) 

all = [two_l,three_l,four_l,five_l,six_l,seven_l,eight_l,nine_l,ten_l] 
cord = range(1,10) 
labels = ["two_let", "three_let", "four_let", "five_let", "six_let", "seven_let", "eight_let", "nine_let", "ten_let"] 


import pylab 
pylab.bar(cord,all, color='#88aa33') 
xticks(cord, labels, rotation='vertical') 
pylab.show()

您可以使用关键字参数align在酒吧命令使标签在酒吧的中心：

pylab.bar(cord,all, color='#88aa33', align='center')

为了使更多的空间标签，你可以用subplots_adjust函数调整图的大小和位置：

subplots_adjust(bottom=0.25)

为标签留出足够的空间也可以自动完成：

from mpl_toolkits.axes_grid1.axes_divider import make_axes_area_auto_adjustable 
make_axes_area_auto_adjustable(gca())
