[Matplotlib-users] xlim with dates
Hi there, does anyone know if there's a simple way to set an axis limit to a date? viewlim_to_dt() looks promising, but I can't figure out how to use it...

Thanks a lot, Alex Alex, I've done something like this in the past: ax.set_xlim( ( min_val, max_val ) ) # improve formatting fig.autofmt_xdate( bottom = 0.20001, rotation = 30, ha = 'right' ) where min_val and max_val are values from matplotlib.dates.date2num( dt ) because dt is a datetime object, which is not the format matplotlib uses. So, setting the xlimit ( or ylimit ) using the values expected by matplotlib manually is one option. def date2num(d): *d* is either a :class:`datetime` instance or a sequence of datetimes. Return value is a floating point number (or sequence of floats) which gives number of days (fraction part represents hours, minutes, seconds) since 0001-01-01 00:00:00 UTC. -Erik -- View this message in context: http://old.nabble.com/xlim-with-dates-tp27881612p27882067.html Sent from the matplotlib - users mailing list archive at Nabble.com. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

If you've plotted using dates, just use dates for the limits: import matplotlib.pyplot as plt import numpy as np from datetime import datetime, timedelta s = datetime.now() x = np.array([s, s + timedelta(hours=3)]) y = np.arange(1,3) plt.plot(x,y) plt.xlim(s - timedelta(minutes=30), s + timedelta(hours=4)) plt.show() Ryan -- Ryan May Graduate Research Assistant School of Meteorology University of Oklahoma -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
