Matplotlib.axes.Axes.tick_params() in Python
  • Last Updated : 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.

matplotlib.axes.Axes.tick_params() Function

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 function
import matplotlib.pyplot as plt
import 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 = .005
kwargs = 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:




# Implementation of matplotlib function
import matplotlib.pyplot as plt

    ax.set_frame_on(True)
    ax.patch.set_visible(False)

fig, host = plt.subplots()

par2 = host.twinx()
  
# Offset the right spine of par2.
# The ticks and label have already been
# placed on the right by twinx above.
par2.spines["right"].set_position(("axes"
                                   1.2))
  
# Having been created by twinx, par2 
# has its frame off, so the line of its
# detached spine is invisible.  First,
# activate the frame but make the patch
# and spines invisible.
make_patch_spines_invisible(par2)
  
# Second, show the right spine.
par2.spines["right"].set_visible(True)
  
p1, = host.plot([0, 1, 2], [0, 1, 2], "b-",
                label ="Y-label 1")

                "g-", label ="Y-label 3")
  
host.set_xlim(0.25, 1.75)
host.set_ylim(0.25, 1.75)
par1.set_ylim(0, 40)
par2.set_ylim(10, 500)
  
host.set_xlabel("X-label")
host.set_ylabel("Y-label 1")

                 colors = p1.get_color(),
                 **tkw)
