Python中的 Matplotlib.axis.Axis.set_sketch_params()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.set_sketch_params()函数

matplotlib 库的轴模块中的Axis.set_sketch_params()函数用于设置草图参数。

Syntax: Axis.set_sketch_params(self, scale=None, length=None, randomness=None) 
 

Parameters: This method accepts the following parameters. 

• scale: This parameter is the amplitude of the wiggle perpendicular to the source line, in pixels.
• length: This parameter is the length of the wiggle along the line, in pixels.
• randomness: This parameter is the scale factor by which the length is shrunken or expanded.

Return value: This method does not return any value.
