Python 中的 Matplotlib.axis.Axis.grid()函数
原文:https://www.geeksforgeeks.org/matplotlib-axis-axis-grid-function-in-python/
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.grid()函数
matplotlib 库的轴模块中的 Axis.grid()函数用于配置网格线。
语法: Axis.grid(self，b=None，其中='major '，**kwargs)
参数:该方法接受以下参数。
- b : 该参数为可选参数，是否显示网格线。
- 哪个:这个参数也是可选参数，是要应用更改的网格线。
返回值:此方法不返回值。
以下示例说明 matplotlib.axis.Axis.grid()函数在 matplotlib.axis: 示例 1:

# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
import numpy as np
fig, ax = plt.subplots()
ax.plot([1, 2, 3])
ax.xaxis.grid()
fig.suptitle("Matplotlib.axis.Axis.grid()\

plt.show()
输出:
例 2:

# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(-5, 5, 0.01)
y1 = -3 * x*x + 10 * x + 10
y2 = 3 * x*x + x
fig, [ax, ax1] = plt.subplots(2, 1,
sharex = True)
ax.plot(x, y1, x, y2, color ='black')
ax.fill_between(x, y1, y2, where = y2 >y1,
facecolor ='green',
alpha = 0.8)
ax.fill_between(x, y1, y2, where = y2 <= y1,
facecolor ='black',
alpha = 0.8)
ax.xaxis.grid(True, color ="black")
ax.set_title('\n Grid in X-axis',
fontsize = 12, fontweight ='bold')
ax1.plot(x, y1, x, y2, color ='black')
ax1.fill_between(x, y1, y2, where = y2 >y1,
facecolor ='green',
alpha = 0.8)
ax1.fill_between(x, y1, y2, where = y2 <= y1,
facecolor ='black',
alpha = 0.8)
ax1.yaxis.grid(True, color ="black")
ax1.set_title('Grid in y-axis',
fontsize = 12, fontweight ='bold')
fig.suptitle("Matplotlib.axis.Axis.grid()\
Function Example", fontsize = 12, fontweight ='bold')
plt.show()
输出:
