Matplotlib.axis.Axis.set_pickradius() function in Python

Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. It is an amazing visualization library in Python for 2D plots of arrays and used for working with the broader SciPy stack.

Matplotlib.axis.Axis.set_pickradius() Function

The Axis.set_pickradius() function in axis module of matplotlib library is used to set the depth of the axis used by the picker 

Syntax: Axis.set_pickradius(self, pickradius) 

Parameters: This method accepts the following parameters. 

• pickradius: This parameter is the float value.

Return value: This method does not return any value. 

Below examples illustrate the matplotlib.axis.Axis.set_pickradius() function in matplotlib.axis:

Example 1:

Python3

# 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-')

ax.grid()

ax.yaxis.set_pickradius(-3)
ax.xaxis.set_pickradius(3)

plt.show()

Output:

Example 2:

Python3

# Implementation of matplotlib function
from matplotlib.axis import Axis
import numpy as np
np.random.seed(19680801)
import matplotlib.pyplot as plt

volume = np.random.rayleigh(27, size = 100)
amount = np.random.poisson(7, size = 100)
ranking = np.random.normal(size = 100)
price = np.random.uniform(1, 7, size = 100)

fig, ax = plt.subplots()

scatter = ax.scatter(volume * 2,
                     amount**3,
                     c = ranking,
                     s = price**3,
                     vmin = -3,
                     vmax = 3,
                     cmap ="Spectral")
ax.yaxis.set_pickradius(25)
ax.xaxis.set_pickradius(5)
ax.grid()
