[FIXED] How to add such line in the axis

Issue

How could I add the lines in axis to highlight the ticks? This is the examples: https://i.stack.imgur.com/wwOtm.png

Solution

You can use the length and width parameters in ax.tick_params like

import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0,10,10)
y = x

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

ax.tick_params(direction='in', length=10, width=3, color='r')
