# Matplotlib.axis.Axis.set_smart_bounds() function in Python

• Last Updated : 08 Jun, 2020

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_smart_bounds() Function

The Axis.set_smart_bounds() function in axis module of matplotlib library is used to set the axis to have smart bounds.

Syntax: Axis.set_smart_bounds(self, value)

Parameters: This method accepts the following parameters.

• value: This parameter is the bool value.

Return value: This method does not return any value.

Below examples illustrate the matplotlib.axis.Axis.set_smart_bounds() 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`` ` ` ` `fig ``=` `plt.figure()``x ``=` `np.linspace(``-``np.pi, np.pi, ``100``)``y ``=` `2``*``np.sin(x)`` ` `ax ``=` `fig.add_subplot()``ax.set_title(``'centered spines'``)``ax.plot(x, y)`` ` `ax.spines[``'left'``].set_position(``'center'``)``ax.spines[``'right'``].set_color(``'none'``)``ax.spines[``'bottom'``].set_position(``'center'``)``ax.spines[``'top'``].set_color(``'none'``)``ax.spines[``'left'``].set_smart_bounds(``True``)``ax.spines[``'bottom'``].set_smart_bounds(``True``)`` ` `ax.xaxis.set_ticks_position(``'bottom'``)``ax.yaxis.set_ticks_position(``'left'``)`` ` `ax.grid() `` ` `fig.suptitle(``"""matplotlib.axis.Axis.set_smart_bounds()``function Example\n"""``, fontweight ``=``"bold")  ``   ` `plt.show()`
