Python中的 Matplotlib.pyplot.axes()

Pyplot是matplotlib的另一个模块，它使用户能够将 MATLAB 集成到Python环境中，从而提供类似 MATLAB 的界面，并使Python具有可视化的交互性。

Matplotlib.pyplot.axes()

pyplot.axes是 matplotlib 库的一个函数，可将轴添加到当前图形并使其成为当前轴。它的输出取决于使用的参数。

Syntax: matplotlib.pyplot.axes(*args, **kwargs)

Parameters:
*args: It may include either None(nothing) or 4 tuples of float type

• none: It gives a new full window axes
• 4 tuples: It takes 4 tuples as list i.e [left bottom width height] and gives a window of these dimensions as axes.

**kwargs: There are several keyword arguments(kwargs) used as parameters to pyplot.axes(), most common include facecolor, gid, in_layout, label, position, xlim, ylim, etc.

示例 1：

# importing matplot library along 
# with necessary modules
import matplotlib.pyplot as plt
  
  
# providing values to x and y 
x = [8, 5, 11, 13, 16, 23]
y = [14, 8, 21, 7, 12, 15]
  
# to plot x and y
plt.plot(x, y)
  
# to generate the full window axes
plt.axes()

输出：

示例 2：

# importing matplot library along 
# with necessary modules
import matplotlib.pyplot as plt
  
  
# providing values to x and y 
x = [8, 5, 11, 13, 16, 23]
y = [14, 8, 21, 7, 12, 15]
  
# to plot x and y
#plt.plot(x, y)
# to generate window of custom 
# dimensions [left, bottom, width,
# height] along with the facecolor 
plt.axes([0, 2.0, 2.0, 2.0], facecolor = 'black') 

输出：
