[SciPy-user] Converting arrays to dates for plot_date()
Thu May 1 15:15:08 CDT 2008
I'm sure there is a simple way to do this that I'm missing. I'm coming form a matlab background and am still having trouble understanding the interactions between arrays and lists etc
I have a file with time series data
1986 7 8 32.1
1986 7 9 42.5
1986 7 10 22.2
I've read this in using loadtxt to the arrays : year,month,day & data
What I want to do is use matplotlibs plot_date() command to plot the data against the date.
I've worked out that I can use something like
to generate the list of dates for plot_date()
but I can't work out how to convert
year = array([2006.0,2007.0])
month = array([11,12])
day = array([1,2])
into the form
datestring = array(['2006-11-1','2007-12-2'])
I've also tried using the datetime() function but I've worked out that doesn't work with numpy arrays.
any pointers/help would be greatly appreciated.
