[Matplotlib-users] Formatter dates

2010-11-17 Thread Tim Åberg
Hello! I have now been tampering with a custom formatter and the more i think about it the more i feel there must be a more easy soulution. I have a set of values that are plotted over time (i use date2num, to get the conversion from date to num), i also have a list with dates that corresponds

yes, it looks like this is the right file (when I look at matplotlib.__file__) Now tracing which routines are run when doing this, it looks like it looks for projection in projections/__init__.py after going through line 675 of figure.py It looks like add_subplot of plt.figure() is not compatible

I just checked it up, and it had some nice function, the timeseries looked nice and maybe i can use it in some way (time_series looked interesting) . I dont want to go away from Linecollection way of plotting due to its speed or is the timeseries-way a fast way of plotting? Date: Wed, 17 N

Hi folks, I want to bin sevaral arrays of data and superimpose them in a single plot. The simplest approach is to fire several times > hist(data_i, N) My problem is that I want to make a loglog plot (i.e. putting a logscale on the X axis too, something that hist doesn't allow me to do). So what

There is numpy.histogram, which will give you the histogram without the plots. But I have had little trouble using hist on log-log plots: Try this (in ipython -pylab or with ">>> from pylab import *; import numpy"): >>> x = numpy.random.lognormal(size=1e4) >>> bins = logspace(-1.5, 1.5, 100) >>>
