原文:https://www . geesforgeks . org/matplotlib-axis-axis-get _ picker-python 中的函数/
Matplotlib 是 Python 中的一个库，是 NumPy 库的数值-数学扩展。这是一个神奇的 Python 可视化库，用于 2D 数组图，并用于处理更广泛的 SciPy 堆栈。
matplotlib . axis . axis . get _ picker()函数
matplotlib 库的 Axis 模块中的 Axis.get_picker()函数用于定义艺术家的拾取行为。
语法: Axis.get_picker(self)
参数:该方法不接受任何参数。
返回值:此方法返回艺术家的采摘行为。
下面的例子说明了 matplotlib . axis . axis . get _ picker()函数在 matplotlib.axis:
例 1:
Python 3
# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
import matplotlib.pyplot as plt
np.random.seed(19680801)
volume = np.random.rayleigh(7, 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,
amount,
c = ranking,
s = price * 3,
vmin = -3,
vmax = 3,
cmap = "Spectral")
legend1 = ax.legend(*scatter.legend_elements(num = 5),
loc = "upper left",
title = "Ranking")
ax.add_artist(legend1)
ax.text(8, 8, "Value return : "
+ str(Axis.get_picker(ax)),
fontweight = "bold",
fontsize = 18)
fig.suptitle("""matplotlib.axis.Axis.get_picker()
function Example\n""", fontweight ="bold")
plt.show()
输出:
例 2:
Python 3
# Implementation of matplotlib function
from matplotlib.axis import Axis
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-', picker = 5)
ax.set_picker(True)
ax.text(0.48, 0.3, "Value return : "
+ str(Axis.get_picker(ax)),
fontweight = "bold",
fontsize = 18)
fig.suptitle("""matplotlib.axis.Axis.get_picker()
function Example\n""", fontweight ="bold")
plt.show()
输出:
