Hi, [cross posted to egenix and matplotlib]
I have been using the egenix mxDateTime module and want to plot some of the dates with Matplotlib (pylab). Pylab uses num2date and date2num to covert datesandtimes to floating point values for plotting. Unfortunately if you give pylab date2num an egenix DateTime object, pylab bombs. Is there a simple way to use egenix DateTime objects with Pylab? Below is a simple example #D:\apps\Python23\python.exe from datetime import * from mx.DateTime import * from pylab import * # This works a=datetime(2005,10,10,5,5,5) print a # This works b=DateTime(2005,10,10,5,5,5) print b # This works c=date2num(a) print c # This fails d=date2num(b) print d The output and failure message is: 2005-10-10 05:05:05 2005-10-10 05:05:05.00 732229.211863 Traceback (most recent call last): File "datetime-problem.py", line 20, in ? d=date2num(b) File "D:\apps\Python23\lib\site-packages\matplotlib\dates.py", line 174, in da te2num if not iterable(d): return _to_ordinalf(d) File "D:\apps\Python23\lib\site-packages\matplotlib\dates.py", line 137, in _t o_ordinalf base = dt.toordinal() AttributeError: toordinal thanks, Simon ------------------------------------------------------------------------- Using Tomcat but need to do more?
