原文:https://www . geeksforgeeks . org/matplotlib-axis-axis-get _ majorticklabels-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 _ majotick labels()函数
matplotlib 库的 Axis 模块中的axis . get _ majoticlabels()函数用于获取主要 ticklabels 的文本实例列表。
语法:axis . get _ majorticklabels(self)
参数:该方法不接受任何参数。
返回值:该方法返回主要标签的文本实例列表。
下面的例子说明了 matplotlib.axis . axis . get _ majotick labels()函数在 matplotlib . axis 中的作用:
例 1:
Python 3
# Implementation of matplotlib function
import numpy as np
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
import matplotlib.ticker as ticker
np.random.seed(19680801)
fig, ax = plt.subplots()
ax.plot(100*np.random.rand(20))
formatter = ticker.FormatStrFormatter('%1.2f')
Axis.set_major_formatter(ax.yaxis, formatter)
print("Value of get_major_ticks() :")
for i in ax.xaxis.get_majorticklabels():
print(i)
plt.title("Matplotlib.axis.Axis.get_majorticklabels()\n\
Function Example", fontsize = 12, fontweight ='bold')
plt.show()
输出:
Value of get_majorticklabels() :
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
Text(0, 0, '')
例 2:
Python 3
# Implementation of matplotlib function
from matplotlib.axis import Axis
from matplotlib.artist import Artist
import matplotlib.pyplot as plt
import numpy as np
np.random.seed(19680801)
n = 100000
x = np.random.standard_normal(n)
y = 2 * np.random.standard_normal(n)
z =[1, 2, 3, 4]
xmin = x.min()
xmax = x.max()
ymin = y.min()
ymax = y.max()
fig, ax = plt.subplots()
hb = ax.hexbin(x, y,
gridsize = 50,
bins ='log',
cmap ='BuGn')
ax.set(xlim =(xmin, xmax), ylim =(ymin, ymax))
ax.xaxis.set_ticklabels(["A","B","C","D","E","F","G","H","I","J","K"])
print("Value of get_majorticklabels() :")
for i in ax.xaxis.get_majorticklabels():
print(i)
plt.title("Matplotlib.axis.Axis.get_majorticklabels()\n\
Function Example", fontsize = 12, fontweight ='bold')
plt.show()
输出:
Value of get_majorticklabels() :
Text(0, 0, 'A')
Text(0, 0, 'B')
Text(0, 0, 'C')
Text(0, 0, 'D')
Text(0, 0, 'E')
Text(0, 0, 'F')
Text(0, 0, 'G')
Text(0, 0, 'H')
Text(0, 0, 'I')
Text(0, 0, 'J')
Text(0, 0, 'K')
