这里可能会有一些混乱,Axes3D具有轴的属性w_xaxis,w_yaxis和w_zaxis,而不是通常的xaxix,yaxis等.
UPDATE现在使用函数来格式化标签.
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np
import matplotlib.dates as dates
import datetime, random
import matplotlib.ticker as ticker
def random_date():
date = datetime.date(2008, 12,01)
while 1:
date += datetime.timedelta(days=30)
yield (date)
def format_date(x, pos=None):
return dates.num2date(x).strftime(‘%Y-%m-%d’) #use FuncFormatter to format dates
r_d = random_date()
some_dates = [dates.date2num(r_d.next()) for i in range(0,20)]
fig = plt.figure()
ax = Axes3D(fig,rect=[0,0.1,1,1]) #make room for date labels
for c, z in zip([‘r’, ‘g’, ‘b’, ‘y’], [30, 20, 10, 0]):
xs = np.array(some_dates)
ys = np.random.rand(20)
ax.bar(xs, ys, zs=z, zdir=’y’, color=c, alpha=0.8,width=8)
ax.w_xaxis.set_major_locator(ticker.FixedLocator(some_dates)) # I want all the dates on my xaxis
ax.w_xaxis.set_major_formatter(ticker.FuncFormatter(format_date))
for tl in ax.w_xaxis.get_ticklabels(): # re-create what autofmt_xdate but with w_xaxis
tl.set_ha(‘right’)
tl.set_rotation(30)
ax.set_ylabel(‘Series’)
ax.set_zlabel(‘Amount’)
plt.show()
