Python中的 Matplotlib.axis.Axis.set_label_coords()函数
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。它是Python中用于二维数组图的惊人可视化库,用于处理更广泛的 SciPy 堆栈。
Matplotlib.axis.Axis.set_label_coords()函数
matplotlib库的axis模块中的axis.set_label_coords()函数用于设置标签的坐标。
Syntax: Axis.set_label_coords(self, x, y, transform=None)
Parameters: This method accepts the following parameters.
- x,y: These parameter are the coordinates of the label.
Return value: This method does not returns any value.
以下示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.set_label_coords()函数:
示例 1:
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
fig, ax2 = plt.subplots(sharex = True)
fig.subplots_adjust(left=0.2, wspace=0.6)
box = dict(facecolor='green', pad=5, alpha=0.2)
ax2.plot(20*np.random.rand(10))
ax2.set_xlabel('X - Label', bbox=box)
ax2.set_xlim(0, 10)
Axis.set_label_coords(ax2.xaxis, 0.5, 0.95)
fig.suptitle("Matplotlib.axis.Axis.set_label_coords()\

plt.show()
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
fig, (ax1, ax2) = plt.subplots(2, 1, sharex = True)
fig.subplots_adjust(left=0.2, wspace=0.6)
box = dict(facecolor='green', pad=5, alpha=0.2)
np.random.seed(19680801)
ax1.plot(2*np.random.rand(10))
ax1.set_title('Label is not aligned')
ax1.set_ylabel('Default', bbox=box)
ax1.set_ylim(0, 20)
ax2.set_title('\nLabel is aligned')
ax2.plot(20*np.random.rand(10))
ax2.set_ylabel('Adjusted', bbox=box)
ax2.set_ylim(0, 20)
Axis.set_label_coords(ax2.yaxis,1.1, 0.5)
fig.suptitle("Matplotlib.axis.Axis.set_label_coords()\
Function Example", fontsize = 12, fontweight ='bold')
plt.show()
输出:
