Dear Martin,
I worked out a similar example for your reference as I don't catch your
example very well.
fig =
plt.figure()
ax1 =
fig.add_subplot(211)
ax2 =
fig.add_subplot(212)
arrlist = [np.random.normal(size=100) for i in
range(50)]
ret =
ax1.hist(arrlist,histtype='barstacked')
reclist = [patchlist[0] for patchlist in
ret[2]]
labellist = ['data'+str(i) for i in
range(50)]
ax2.legend(reclist,labellist,loc='upper
left',bbox_to_anchor=(0,0,1,1),borderaxespad=0.,ncol=5,mode='expand')
ax2.set_frame_on(False)
ax2.tick_params(bottom='off',left='off',right='off',top='off')
plt.setp(ax2.get_yticklabels(),visible=False)
plt.setp(ax2.get_xticklabels(),visible=False)
you're asking some object-oriented way, I personally don't think using
pylab and set_tight_layout are the good way
to be "object-oriented" as pylab is only a bounding wrapper by my
understanding (maybe I am wrong!). legend and
hist are all matplotlib.axes.Axes method.
Also, I think it's unrealistic to ask the figure do a nice job for you if
there are 50 legned handlers and you want to show
them in 2 columns with a very high width/height ratio of the figure....
hope it could be of a bit help,
cheers,
Chao
