Python中的 Matplotlib.axes.Axes.get_adjustable()
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。 Axes 类包含大部分图形元素:Axis、Tick、Line2D、Text、Polygon 等,并设置坐标系。 Axes 的实例通过回调属性支持回调。
matplotlib.axes.Axes.get_adjustable()函数
matplotlib 库的 axes 模块中的Axes.get_adjustable()函数用于获取给定 Axes 的哪个参数来实现给定的方面。
Syntax: Axes.get_adjustable(self)
Parameters: This method does not accepts any parameters.
Return value: This method returns the adjustable value.
下面的示例说明了 matplotlib.axes 中的 matplotlib.axes.Axes.get_adjustable()函数:
示例 1:
# ImpleIn Reviewtation of matplotlib function
import matplotlib.pyplot as plt
fig, (ax1, ax2) = plt.subplots(1, 2)
ax1.set_xscale("log")
ax1.set_yscale("log")
ax1.set_xlim(1e1, 1e3)
ax1.set_ylim(1e2, 1e3)
ax1.set_aspect(1)
ax1.set_title("Axes 1")
ax2.set_xscale("log")
ax2.set_yscale("log")
ax2.set_adjustable("datalim")
ax2.plot([1, 113, 10], [1, 119, 100], "o-")
ax2.set_xlim(1e-1, 1e2)
ax2.set_ylim(1e-1, 1e3)
ax2.set_aspect(1)
ax2.set_title("Axes 2")
w = ax1.get_adjustable()
w1 = ax2.get_adjustable()
ax1.text(20, 400,
" Value return by\n get_adjustable() : " +str(w))
ax2.text(1, 200,
" Value return by \nget_adjustable() : \n " +str(w1))
