Matplotlib.axes.Axes.tick_params() in Python

21 Apr, 2020
Matplotlib is a library in Python and it is numerical – mathematical extension for NumPy library. The Axes Class contains most of the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. And the instances of Axes supports callbacks through a callbacks attribute.
The Axes.tick_params() function in axes module of matplotlib library is used to control behavior of major tick locators.
Syntax: Axes.tick_params(self, axis=’both’, **kwargs)
Parameters: This method accepts the following parameters.
axis : This parameter is the used to which axis to apply the parameters to.
Return value: This method does not returns any value.
Below examples illustrate the matplotlib.axes.Axes.tick_params() function in matplotlib.axes:
Example 1:
# Implementation of matplotlib functionimport matplotlib.pyplot as pltimport numpy as np  values = np.array([    0.015, 0.166, 0.133, 0.159, 0.041,    0.024, 0.195, 0.039, 0.161, 0.018,    0.143, 0.056, 0.125, 0.096, 0.094,    0.051, 0.043, 0.021, 0.138, 0.075,    0.109, 0.195, 0.050, 0.074, 0.079,    0.155, 0.020, 0.010, 0.061, 0.008])  values[[3, 14]] += .8  fig, (ax, ax2) = plt.subplots(2, 1, sharex = True)  ax.plot(values, "o-", color ="green")ax2.plot(values, "o-", color ="green")  ax.set_ylim(.78, 1.) ax2.set_ylim(0, .22)  ax.spines['bottom'].set_visible(False)ax2.spines['top'].set_visible(False)ax.xaxis.tick_top()ax.tick_params(labeltop = False)ax2.xaxis.tick_bottom()  d = .005kwargs = dict(transform = ax.transAxes,              color ='k', clip_on = False)  ax.plot((-d, +d), (-d, +d), **kwargs)       ax.plot((1 - d, 1 + d), (-d, +d), **kwargs)   kwargs.update(transform = ax2.transAxes)  ax2.plot((-d, +d), (1 - d, 1 + d), **kwargs)ax2.plot((1 - d, 1 + d), (1 - d, 1 + d), **kwargs)   fig.suptitle('matplotlib.axes.Axes.tick_params()\function Example\n\n', fontweight ="bold")  plt.show()

Example 2:
