我想从一个轴心档案中划出数据:

13/7/2009 12:50:50   147425826 0 4716298 36645030 3757926 228230
13/7/2009 13:5:1     147517368 0 4717954 36687455 3761270 228375
13/7/2009 13:10:0    147550312 0 4718599 36701448 3762634 228437

日期应为x轴,其余各栏应为轴线(分行)。

问题回答

one of the best python package for plotting data is matplotlib.

那么,你只得把你的投入文件归为:

import time

data = []
for line in open( input.txt ):
    date,time,*samples = line.split()
    data.append((time.strptime(str.join(   , (date, time)),  %d/%m/%Y %H:%M:%S ), samples))

然后利用校正来绘制数据......

(上述平级代码可改写,使用一份清单核对表,可能提高记忆效率,因为它将含蓄地使用探测器和zy评价,而不是在名单上储存全部数据)
