Tommy,
I'll try to answer your points in order:
1) Oops. That should have been "xticks".
import matplotlib.pyplot as plt
plt.plot([1,3,2])
ticks, labels = plt.xticks()
plt.xticks(ticks, horizontalalignment='left')
plt.show()
2) Sorry for the ambiguity. "OO" is short for object-oriented. There are
two different approaches that people tend to use to make plots (although
they can be mixed): 1) the "pyplot" way, which uses the pyplot wrapper
functions and 2) the object-oriented way, which modifies the objects
directly. This is what you did in your example where you snag the axes
objects and operate on them directly. The "OO" way is ultimately more
powerful, because the pyplot wrapper functions override some of your
control. For example, because you want twin axes, you might not be able to
use the pyplot.xticks function (Others, correct me if I'm wrong.), and you
lose some fine control. See next example.
3) I know it *seems* like the for loop is an "ugly hack". However, you have
to realize that this ultimately gives you a TON of control. Let's say, for
example, that you wanted only one of the labels to be large and red to
highlight a certain value. Using a modified version of your example, we get
this:
______________
import matplotlib.pyplot as plt
fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twinx()
labels = ax2.yaxis.get_ticklabels()
[l.set_horizontalalignment('right') for l in labels]
labels[2].set_color('red')
labels[2].set_fontsize(20)
ax2.tick_params(pad=20)
ax1.plot(list(range(11)))
ax1.set_xlim(0,10)
ax2.set_ylim(0,10)
plt.show()
____________
I personally think that this level of control is very, very cool and one of
the big selling points for MPL in general.
Okay. If you want to set the alignment all the time, there might be a way
to control this with matplotlibrc or style sheets:
http://matplotlib.org/users/customizing.html
http://matplotlib.org/users/style_sheets.html
However, I'm not the biggest fan of changing matplotlibrc. Mostly because
if others try to reproduce your plots, they also need your rc file as well.
I haven't used style sheets yet, but that might be a fix to this issue (for
me at least).
Hope that helps.
Ryan
