Python中的 Matplotlib.figure.Figure.get_edgecolor()
Matplotlib是Python中的一个库,它是 NumPy 库的数值数学扩展。 figure 模块提供了顶级 Artist,即 Figure,其中包含所有绘图元素。该模块用于控制所有绘图元素的子图和顶级容器的默认间距。
matplotlib.figure.Figure.get_edgecolor() 方法
matplotlib库的get_edgecolor()方法figure模块用于获取Figure矩形的边缘颜色。
Syntax: get_edgecolor(self)
Parameters: This method does not accept any parameters.
Returns: This method return the edge color of the Figure rectangle.
下面的示例说明了 matplotlib.figure 中的 matplotlib.figure.Figure.get_edgecolor()函数:
示例 1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
from matplotlib.figure import Figure
from mpl_toolkits.axisartist.axislines import Subplot
import numpy as np
fig = plt.figure(edgecolor ="green")
ax = Subplot(fig, 111)
fig.add_subplot(ax)
w = fig.get_edgecolor()
ax.text(0.2, 0.5, "Value Return by get_edgecolor() :\n"
+str(w),
fontweight ="bold")
fig.canvas.draw()
fig.suptitle('matplotlib.figure.Figure.get_edgecolor() \
function Example', fontweight ="bold")
plt.show()
输出:
示例 2:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
from matplotlib.figure import Figure
import numpy as np
fig = plt.figure(edgecolor = "red", figsize =(7, 6))
ax = fig.add_axes([0.1, 0.1, 0.8, 0.8])
xx = np.arange(0, 2 * np.pi, 0.01)
ax.plot(xx, np.sin(xx))
w = fig.get_edgecolor()
ax.text(2, 0, "Value Return by get_edgecolor() :\n"
+ str(w),
fontweight ="bold")
fig.canvas.draw()
fig.suptitle('matplotlib.figure.Figure.get_edgecolor()\
function Example', fontweight ="bold")
plt.show()
输出:
