Python 中的 matplotlib . axis . axis . get _ major chirines()函数
原文:https://www . geeksforgeeks . org/matplotlib-axis-axis-get _ major chirines-python 中的函数/
Matplotlib 是 Python 中的一个库，是 NumPy 库的数值-数学扩展。这是一个神奇的 Python 可视化库，用于 2D 数组图，并用于处理更广泛的 SciPy 堆栈。
matplotlib . axis . axis . get _ major 怕痒()函数
matplotlib 库的 Axis 模块中的axis . get _ major clinicnes()函数用来获取一个主刻度线作为 Line2D 实例的列表。
语法:axis . get _ major 怕痒(自我)
参数:该方法不接受任何参数。
返回值:该方法将主要刻度线作为线 2D 实例列表返回
下面的例子说明了 matplotlib.axis . axis . get _ major chirines()函数在 matplotlib . axis 中的作用:
例 1:
Python 3
# Implementation of matplotlib function
from matplotlib.axis import Axis
from matplotlib.artist import Artist
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
def tellme(s):
ax.set_title(s, fontsize = 16)
fig.canvas.draw()
renderer = fig.canvas.renderer
Artist.draw(ax, renderer)
tellme("Matplotlib.axis.Axis.get_majorticklines()\n\
Function Example")
ax.grid()
print("Value of get_majorticklines() :")
for i in ax.xaxis.get_majorticklines():
print(i)
plt.show()
输出:
Value of get_majorticklines() :
Line2D((0,0))
Line2D()
Line2D((0.2,0))
Line2D()
Line2D((0.4,0))
Line2D()
Line2D((0.6,0))
Line2D()
Line2D((0.8,0))
Line2D()
Line2D((1,0))
Line2D()
例 2:
Python 3
# Implementation of matplotlib function
from matplotlib.axis import Axis
from matplotlib.artist import Artist
from mpl_toolkits.mplot3d import axes3d
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111, projection ='3d')
X, Y, Z = axes3d.get_test_data(0.1)
ax.plot_wireframe(X, Y, Z, rstride = 5,
cstride = 5)
ax.view_init(30, 50)
fig.canvas.draw()
renderer = fig.canvas.renderer
Artist.draw(ax, renderer)
fig.suptitle('Matplotlib.axis.Axis.get_majorticklines()\n\
Function Example')
ax.grid()
print("Value of get_majorticklines() :")
for i in ax.xaxis.get_majorticklines():
print(i)
plt.show()
输出:
Value of get_majorticklines() :
