Python中的 Matplotlib.axis.Axis.get_tightbbox()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.get_tightbbox()函数
matplotlib 库的轴模块中的Axis.get_tightbbox()函数用于获取包围轴的边界框。
Syntax: Axis.get_tightbbox(self, renderer)
Parameters: This method accepts the following parameters.
- renderer: This parameter is the RendererBase instance
renderer
Return value: This method returns the bounding box that encloses the axis.
下面的示例说明了 matplotlib.axis 中的 matplotlib.axis.Axis.get_tightbbox()函数:
示例 1:
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import matplotlib.pyplot as plt
import numpy as np
X = np.arange(-10, 10, 0.5)
Y = np.arange(-10, 10, 0.5)
U, V = np.meshgrid(X, Y)
fig, ax = plt.subplots()
ax.quiver(X, Y, U, V)
ax.invert_xaxis()
w = Axis.get_tightbbox(ax.xaxis, fig.canvas.get_renderer())
print("Value Return :\n"+str(w))
ax.grid()
fig.suptitle("""matplotlib.axis.Axis.get_tightbbox()
function Example\n""", fontweight ="bold")
plt.show()
Python3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
xx = np.random.rand(8, 6)
fig, ax = plt.subplots()
m = ax.pcolor(xx)
m.set_zorder(-2)
w = Axis.get_tightbbox(ax.xaxis, fig.canvas.get_renderer())
print("Value Return :\n"+str(w))
ax.grid()
fig.suptitle("""matplotlib.axis.Axis.get_tightbbox()
function Example\n""", fontweight ="bold")
plt.show()
输出:
Value Return :
Bbox(x0=75.48368298368294, y0=29.077777777777776, x1=574.7670454545455, y1=43.077777777777776)
