如何更改 x 轴上的数字（matplotlib）

Question

import numpy as np
import matplotlib.pyplot as plt

# Create some mock data
t = np.arange(0.01, 10.0, 0.01)
data1 = np.exp(t)
data2 = np.sin(2 * np.pi * t)

fig, ax1 = plt.subplots()

color = 'tab:red'
ax1.set_xlabel('time (s)')
ax1.set_ylabel('exp', color=color)
ax1.plot(t, data1, color=color)
ax1.tick_params(axis='y', labelcolor=color)

ax2 = ax1.twinx() 

color = 'tab:blue'
ax2.set_ylabel('sin', color=color)  
ax2.plot(t, data2, color=color)
ax2.tick_params(axis='y', labelcolor=color)

fig.tight_layout()  
plt.show()

enter image description here

I wonder if I could change the value on the x-axis. Thank you... (The system forces me to type more words instead of code...)

Answer 1

Use set_xticklabels() with proper list of values.

ax2.set_xticklabels([1999,2000,2001,2002,2003,2004,2005])
