消除 3d 图垂直轴上的科学记数法 (Python)

Question

如何消除 3d 图垂直轴上的科学计数法，并将其替换为整数？例如，我想要 2002 而不是 0.0+2.002e3 我的示例脚本如下：

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import axes3d

yearvec = [2002, 2003, 2004]
plt.close('all')
fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_xlim3d(0, 250)
ax.set_ylim3d(0, 250)
ax.set_zlim3d(yearvec[0], yearvec[-1])

Answer 1

尝试使用 ax.zaxis.set_major_formatter and ax.zaxis.set_major_locator:

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import axes3d
from matplotlib.ticker import FormatStrFormatter, MultipleLocator

yearvec = [2002, 2003, 2004, 2005]
plt.close('all')
fig = plt.figure()
ax = fig.gca(projection='3d')
ax.set_xlim3d(0, 250)
ax.set_ylim3d(0, 250)
ax.set_zlim3d(yearvec[0], yearvec[-1])

majorLocator   = MultipleLocator(1)
ax.zaxis.set_major_locator(majorLocator)
zFormatter = FormatStrFormatter('%d')
ax.zaxis.set_major_formatter(zFormatter)

这就是你想要的？
