Python matplotlib库的artist模块中的set_picker()方法用于定义artist的挑选行为。
语法:Artist.set_picker(self, picker)
参数:此方法接受以下参数,讨论如下:
- picker:该参数用于设置拾取行为。可以是None、bool、float或function。
返回:这个方法是artist的挑选行为。
下面的例子演示了matplotlib中的matplotlib.artist.artist.set_picker()函数:
示例1
# Implementation of matplotlib function
from matplotlib.artist import Artist
import numpy as np
import matplotlib.pyplot as plt
np.random.seed(19680801)
volume = np.random.rayleigh(27, size = 40)
amount = np.random.poisson(7, size = 40)
ranking = np.random.normal(size = 40)
price = np.random.uniform(1, 7, size = 40)
fig, ax = plt.subplots()
scatter = ax.scatter(volume * 2,
amount**3,
c = ranking**3,
s = price**3,
vmin = -3,
vmax = 3,
cmap ="Spectral")
Artist.set_picker(ax, picker = 4)
fig.suptitle('matplotlib.artist.Artist.set_picker()\
function Example', fontweight ="bold")
plt.show()
输出:

# Implementation of matplotlib function
from matplotlib.artist import Artist
import numpy as np
import matplotlib.pyplot as plt
X = np.random.rand(10, 200)
xs = np.mean(X, axis = 1)
ys = np.std(X, axis = 1)
fig = plt.figure()
ax = fig.add_subplot(111)
line, = ax.plot(xs, ys, 'go-')
Artist.set_picker(ax, picker = True)
