Python中的 Matplotlib.figure.Figure()
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() 类
此类是所有绘图元素的顶级容器。 Figure 实例通过回调属性支持回调,回调属性是 CallbackRegistry 实例。
注意:在图中,Base 是matplotlib.artist.Artist 。
Syntax: class matplotlib.figure.Figure(figsize=None, dpi=None, facecolor=None, edgecolor=None, linewidth=0.0, frameon=None, subplotpars=None, tight_layout=None, constrained_layout=None)
Parameters: This accept the following parameters that are described below:
- figsize : This parameter is the Figure dimension (width, height) in inches.
- dpi : This parameter is the dots per inch.
- facecolor : This parameter is the figure patch facecolor.
- edgecolor : This parameter is the figure patch edge color.
- linewidth : This parameter is the linewidth of the frame.
- frameon : This parameter is the suppress drawing the figure background patch.
- subplotpars : This parameter is the Subplot parameters.
- tight_layout : This parameter is used to adjust subplot parameters.
- constrained_layout : This parameter is used to adjust positioning of plot elements.
Returns: This method return the figure instances.
下面的示例说明了 matplotlib.figure 中的 matplotlib.figure.Figure()函数:
示例 1:
# Implementation of matplotlib function
import matplotlib.pyplot as plt
from matplotlib.figure import Figure
import numpy as np
fig = plt.figure(figsize =(5, 4))
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))
fig.suptitle('matplotlib.figure.Figure() class Example\n\n',
fontweight ="bold")
plt.show()
输出:
示例 2:
# 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(facecolor ="green")
ax = Subplot(fig, 111)
fig.add_subplot(ax)
ax.axis["left"].set_visible(False)
ax.axis["top"].set_visible(False)
fig.suptitle('matplotlib.figure.Figure() class Example\n\n',
fontweight ="bold")
plt.show()
输出:
