Python中的 Matplotlib.pyplot.grid()
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。 Pyplot是Matplotlib模块的基于状态的接口,它提供了一个类似 MATLAB 的接口。
matplotlib.pyplot.grid()函数
matplotlib 库的 pyplot 模块中的grid()函数用于配置网格线。
Syntax: matplotlib.pyplot.grid(b=None, which=’major’, axis=’both’, \*\*kwargs)
Parameters: This method accept the following parameters.
- b : This parameter is an optional parameter, whether to show the grid lines or not.
- which : This parameter is also an optional parameter and it is the grid lines to apply the changes on.
- axis :This parameter is also an optional parameter and it is the axis to apply the changes on.
Returns:This method does not return any value.
下面的示例说明了 matplotlib.pyplot 中的 matplotlib.pyplot.grid()函数:
示例 #1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
import numpy as np
plt.plot([1, 2, 3])
plt.grid()
plt.title('matplotlib.pyplot.grid() function \
Example\n\n', fontweight ="bold")
plt.show()
输出:
示例 #2:
# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt
np.random.seed(19680801)
val, res = 100, 15
x = np.sin(val + res * np.random.randn(10000)) - np.cos(val + res * np.random.randn(10000))
n, bins, patches = plt.hist(x, 200,
density = True,
facecolor ='g',
alpha = 0.5)
plt.grid(True)
plt.title('matplotlib.pyplot.grid() function \
Example\n\n', fontweight ="bold")
plt.show()
输出:
