Dear all,
I hope some of you could help me out. I am currently trying
to generate
some timetables using matplotlib.pyplot.plot_date, having
the time-axis
on the y-axis. Typically, one would like to read these plots
from top to
bottom, from older to newer items (future on the bottom).
Unfortunately,
the default enumeration of the y-axis is the other way
around, and it
resists my attempts to invert its direction e.g. by changing
limits
using matplotlib.pyplot.ylim (Traceback below). I found a
quite old
entry in stackoverflow which is most probably outdated, at
least the
proposed solution did not work for me...
([http://stackoverflow.com/questions/5804969/displaying-an-inverted-vertical-date-axis](http://stackoverflow.com/questions/5804969/displaying-an-inverted-vertical-date-axis)).
Since the longish traceback seems to try to tell me I did
not understand
some kind of important - even trivial - point about those
datetime-axis
maybe some of you came about this problem before?
Thanks, Gerd
P.S.: Traceback after trying to use something like
"matplotlib.pyplot.ylim(ymax,ymin)":

Want excitement?
Manually upgrade your production database.
When you want reliability, choose Perforce.
Perforce version control. Predictably reliable.
