Hm. thanks for the info. But it's not perfect... I get times in my
formats, but not the dates. Here is the sample code:
#!/usr/bin/python
#
# Example boxplot code
#
from pylab import *
from matplotlib.dates import MonthLocator, WeekdayLocator, DateFormatter
from matplotlib.dates import MONDAY,SATURDAY
# fake up some data
set1 = (rand(50)+1) * 100
set2 = (rand(50)+2) * 100
boxplot(set1,positions=[732659])
boxplot(set2,positions=[732660])
ax = gca()
ax.xaxis.set_major_locator(MonthLocator())
ax.xaxis.set_major_formatter(DateFormatter('%D'))
ax.xaxis.set_minor_locator(WeekdayLocator(MONDAY))
ax.yaxis.set_major_formatter(FormatStrFormatter('%3.0f KB/s'))
ax.xaxis_date(None)
setp(ax.get_xticklabels(),'rotation',90,fontsize=8)
show()
==================
And yes, thanks for telling me about the timezone problem. I have
been doing all of my work in GMT, only to be confounded.
We really need a manual that explains all of the axis stuff.
Now, how do I get two boxplots on the same plot?
(This would be SO MUCH EASIER if boxplot would take a list of objects
that listed where the various thingies when...)
