Hi, i try to use the plot_date function and i have some problems, is
anybody can help me
My program :
First to show it's ok to run if i just used the only plot function
from pylab import *
import marshal
import time
import stringlst_date=
points=
belos=[['2', '2', '2', '2', '2', '2', '2', '54', '125', '169', '224', '245', '245', '245', '325', '325', '325', '453', '486', '521', '521', '521', '8596', '9566', '9848', '10064'], [1148378715.6400001, 1148379045.312, 1148379057.7179999, 1148379069.375, 1148379331.921, 1148390222.3280001, 1148390265.2650001, 1148396382.562, 1148464116.609, 1148481671.6559999, 1148534908.2520001, 1148551483.8299999, 1148573370.8770001, 1148589279.517, 1148625453.8429999, 1148640384.5150001, 1148659451.25, 1148709552.921, 1148740419.375, 1148799935.5780001, 1148827804.0, 1148886086.109, 1148915795.984, 1148972914.8429999, 1149001049.671, 1149053926.7650001], ['2:349:7', '2:349:7', '2:349:7', '2:349:7', '2:349:7', '2:349:7', '2:349:7', '3:56:5', '3:56:5', '3:56:5', '3:56:5']]point=belos[0]
dt_date=belos[1]for j in dt_date:
date=time.ctime(j)
lst_date.append(date)print lst_date
for i in point:
a=int(i)
points.append(a)
print belos
print point
print len(point)
print len(lst_date)
#plot (date, point, 'ro')
#show()#plot_date(dt_date, points, '', xdate=True, ydate=False)
plot(dt_date, points, '',)
#savefig('secondfig.png')
show()
The i try with the plot_date function and i got on error:
Traceback (most recent call last):

File "C:\Python24\Lib\site-packages\matplotlib\dates.py", line 154, in _from_ordinalf
dt = datetime.datetime.fromordinal(ix)
ValueError: year is out of range
i want the x axis show me the date on this format : Tue May 23 12:05:15
2006', 'Tue May 23 12:10:45 2006', 'Tue May 23 12:10:57 2006 etc...
Thx for answer
