所以我有一个 3d 实时更新图!它一次只显示一个点,因此我可以轻松跟踪该点的运动!但问题是:
无论我似乎在做什么,该点始终位于图形的中心,并且轴上的刻度线会发生变化以做到这一点。这让我的生活变得非常困难,因为我没有看到关键的动作。这是我的代码:
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
from pylab import *
import time
import pandas as pd
import pickle
def pickleLoad(pickleFile):
pkl_file = open(pickleFile, 'rb')
data = pickle.load(pkl_file)
pkl_file.close()
return data
data = pickleLoad('/Users/ryansaxe/Desktop/kaggle_parkinsons/accelerometry/LILY_dataframe')
data = data.reset_index(drop=True)
df = data.ix[0:,['x.mean','y.mean','z.mean','time']]
ion()
fig = figure()
ax = fig.add_subplot(111, projection='3d')
count = 0
plotting = True
labels = range(-10,11)
ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')
ax.set_yticklabels(labels)
ax.set_xticklabels(labels)
ax.set_zticklabels(labels)
lin = None
while plotting:
df2 = df.ix[count]
count += 1
xs = df2['x.mean']
ys = df2['y.mean']
zs = df2['z.mean']
t = df2['time']
ax.set_title(t)
if lin is not None:
lin.remove()
lin = ax.scatter(xs, ys, zs)
draw()
pause(0.01)
if count > 100:
plotting = False
ioff()
show()
这是数据的示例:
x.mean y.mean z.mean time

6 4.124187 -7.854146 2.727229 2012-01-18 14:00:09
7 4.199698 -8.135596 2.677706 2012-01-18 14:00:10
8 4.407856 -8.133449 2.214902 2012-01-18 14:00:11
9 4.096238 -8.453822 1.359692 2012-01-18 14:00:12
那么我该怎么做才能使刻度线固定以便点移动而不是刻度线改变呢?
