Matplotlib是Python中的一個庫,它是數字的-NumPy庫的數學擴展。它是Python中令人驚歎的可視化庫,用於數組的2D圖,並用於與更廣泛的SciPy堆棧配合使用。
matplotlib.axis.Axis.get_ticklines()函數
matplotlib庫的軸模塊中的Axis.get_ticklines()函數用於獲取刻度線作為Line2D實例的列表。
用法: Axis.get_ticklines(self, minor=False)
參數:此方法接受以下參數。
- minor:此參數包含布爾值。如果為True,則返回次要刻度線,否則返回主次要刻度線。
返回值:此方法將刻度線作為Line2D實例的列表返回。
以下示例說明了matplotlib.axis中的matplotlib.axis.Axis.get_ticklines()函數:
範例1:
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.patches import Polygon
def func(x):
return (x - 4) * (x - 6) * (x - 5) + 100
a, b = 2, 9 # integral limits
x = np.linspace(0, 10)
y = func(x)
fig, ax = plt.subplots()
ax.plot(x, y, "k", linewidth = 2)
ax.set_ylim(bottom = 0)
# Make the shaded region
ix = np.linspace(a, b)
iy = func(ix)
verts = [(a, 0), *zip(ix, iy), (b, 0)]
poly = Polygon(verts, facecolor ='green',
edgecolor ='0.5', alpha = 0.4)
ax.add_patch(poly)
ax.text(0.5 * (a + b), 30,
r"$\int_a ^ b f(x)\mathrm{d}x$",
horizontalalignment ='center',
fontsize = 20)
fig.text(0.9, 0.05, '$x$')
fig.text(0.1, 0.9, '$y$')
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)
ax.set_xticks((a, b-a, b))
ax.set_xticklabels(('$a$', '$valx$', '$b$'))
fig.suptitle('Matplotlib.axis.Axis.get_ticklines()\n\
Function Example', fontweight ="bold")
ax.grid()
print("Value of get_ticklines():")
for i in ax.xaxis.get_ticklines():
print(i)
plt.show()
輸出:
Value of get_ticklines(): Line2D() Line2D() Line2D() Line2D() Line2D() Line2D()
範例2:
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
# Fixing random state for reproducibility
np.random.seed(19680801)
x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(x)
y2 = y + 0.2 * np.random.normal(size = x.shape)
fig, ax = plt.subplots()
ax.plot(x, y)
ax.plot(x, y2)
ax.set_xticks([0, np.pi, 2 * np.pi])
ax.set_xticklabels(['0', r'$\pi$', r'2$\pi$'])
for line in ax.yaxis.get_ticklines():
# line is a Line2D instance
line.set_color('tab:green')
line.set_markersize(25)
line.set_markeredgewidth(3)
ax.spines['left'].set_bounds(-1, 1)
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)
fig.suptitle('Matplotlib.axis.Axis.get_ticklines()\n\
Function Example', fontweight ="bold")
ax.grid()
plt.show()
輸出:
