Python中的 Matplotlib.axes.Axes.get_sketch_params()

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_sketch_params()函数

matplotlib 库的轴模块中的Axes.get_sketch_params()函数用于获取艺术家的草图参数。

Syntax: Axes.get_sketch_params(self)

Parameters: This method does not accepts any parameter.

Returns: This method return the sketch parameters for the artist.

编程需要懂一点英语

下面的示例说明了 matplotlib.axes 中的 matplotlib.axes.Axes.get_sketch_params()函数：

示例 1：

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import matplotlib.colors as mcolors
import matplotlib.gridspec as gridspec
import numpy as np
     
     
plt.rcParams['savefig.facecolor'] = "0.8"
plt.rcParams['figure.figsize'] = 6, 5
     
fig, ax = plt.subplots()
     
ax.plot([1, 2])
     
ax.locator_params("x", nbins = 3)
ax.locator_params("y", nbins = 5)
     
ax.set_xlabel('x-label')
ax.set_ylabel('y-label')
   
ax.text(0.2, 1.8, "Sketch Parameters : "
        +str(ax.get_sketch_params()), 
        fontweight ="bold")
     
fig.suptitle('matplotlib.axes.Axes.get_sketch_params() \
function Example\n\n', fontweight ="bold")
  
plt.show()

输出：
