Matplotlib.axes.Axes.set_yticks() in Python

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.set_yticks() Function

The Axes.set_yticks() function in axes module of matplotlib library is used to Set the y ticks with list of ticks.

Syntax:Axes.set_yticks(self, ticks, minor=False)

Parameters: This method accepts the following parameters.

• ticks : This parameter is the list of y-axis tick locations.
• minor : This parameter is used whether set major ticks or to set minor ticks

Return value: This method does not returns any value.

Below examples illustrate the matplotlib.axes.Axes.set_yticks() function in matplotlib.axes:

Example 1:

# Implementation of matplotlib function
import matplotlib.pyplot as plt
import matplotlib.transforms as mtransforms


fig, ax = plt.subplots()
ax.plot(range(12, 24), range(12))
ax.set_yticks((2, 5, 7, 10))

fig.suptitle('matplotlib.axes.Axes.set_yticks()\
 function Example\n\n', fontweight ="bold")
plt.show()

Output:

Example 2:

# Implementation of matplotlib function
import numpy as np
import matplotlib.pyplot as plt

# Fixing random state for reproducibility
np.random.seed(19680801)

x = np.linspace(0, 2 * np.pi, 100)
y = np.sin(x)
y2 = y + 0.2 * np.random.normal(size = x.shape)

fig, ax = plt.subplots()
ax.plot(x, y)
ax.plot(x, y2)

ax.set_yticks([-1, 0, 1])

ax.spines['left'].set_bounds(-1, 1)
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

fig.suptitle('matplotlib.axes.Axes.set_yticks()\
 function Example\n\n', fontweight ="bold")
fig.canvas.draw()
plt.show()

Output:
