Python 中的 matplotlib . axis . axis . get _ tick label _ extensions()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 _ tick label _ extensions()函数
matplotlib 库的轴模块中的axis . get _ tick label _ extensions()函数用于获取轴两侧刻度标签的范围
语法:axis . get _ tick label _ extensions(self,渲染器)
参数:该方法接受以下参数。
- 渲染器:该参数是渲染器渲染实例 渲染器。
返回值:该方法返回坐标轴任一侧刻度标签的范围
下面的例子说明了 matplotlib . axis . get _ tick label _ extensions()函数在 matplotlib.axis:
例 1:
Python 3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
import numpy as np
X = np.arange(-5, 5, 1)
Y = np.arange(-5, 5, 1)
U, V = np.meshgrid(X, Y)
fig, ax = plt.subplots()
ax.quiver(X, Y, U, V)
ax.invert_xaxis()
w = Axis.get_ticklabel_extents(ax.xaxis,
fig.canvas.get_renderer())
print("Value Return :\n"+str(w))
ax.grid()
fig.suptitle("""matplotlib.axis.Axis.get_ticklabel_extents()
function Example\n""", fontweight ="bold")
plt.show()
输出:
值返回: (Bbox([[98.1079545454545453,29.07777777777777776],[513.603535353535353,43.0777777777777]]),Bbox([[0.0,0.0],[0.0,0.0]))
例 2:
Python 3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
xx = np.random.rand(10, 5)
fig, ax = plt.subplots()
m = ax.pcolor(xx)
m.set_zorder(-2)
w = Axis.get_ticklabel_extents(ax.xaxis, fig.canvas.get_renderer())
print("Value Return :\n"+str(w))
ax.grid()
fig.suptitle("""matplotlib.axis.Axis.get_ticklabel_extents()
function Example\n""", fontweight ="bold")
plt.show()
输出:
值返回: (Bbox([[75.5625,29.07777777777776],[580.4375,43.077777777776]]),Bbox([[0.0,0.0],[0.0,0.0]])
