Matplotlib是Python中的一个库,它是数字的-NumPy库的数学扩展。 Artist类包含用于呈现到FigureCanvas中的对象的Abstract基类。图中所有可见元素都是Artist的子类。
matplotlib.artist.Artist.set_sketch_params()方法
matplotlib库的美工模块中的set_sketch_params()方法用于设置草图参数。
用法:Artist.set_sketch_params(self, scale=None, length=None, randomness=None)
参数:此方法接受以下参数。
- scale:此参数是垂直于源极线的摆动幅度,以像素为单位。
- length:此参数是沿线摆动的长度,以像素为单位。
- randomness:此参数是缩小或扩展长度的比例因子。
返回值:此方法不返回任何值。
以下示例说明了matplotlib中的matplotlib.artist.Artist.set_sketch_params()函数:
范例1:
# Implementation of matplotlib function
from matplotlib.artist import Artist
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')
Artist.set_sketch_params(ax, 100, 100, 20)
fig.suptitle('matplotlib.artist.Artist.set_sketch_params()\
function Example', fontweight ="bold")
plt.show()
输出:
