有没有友友知道python怎么绘制横坐标为时间，纵坐标为气压层的垂直风场呢

1. 类似这样

复制代码

1. import pandas as pd
   
2. import numpy as np
   
3. import matplotlib.pyplot as plt
   
4. from matplotlib.colors import ListedColormap, BoundaryNorm
   
5. from matplotlib.font_manager import FontProperties
   
6. from matplotlib.gridspec import GridSpec
   
7. 
   
8. cmap = ListedColormap(['black', 'blue'])
   
9. cmap.set_over('red')
   
10. norm = BoundaryNorm([0, 4, 8], 2)
    
11. font = FontProperties(fname=r"C:\Windows\Fonts\simsun.ttc")
    
12. barb_increments = {
    
13.     'half': 2,
    
14.     'full': 4,
    
15.     'flag': 20
    
16.     }
    
17. 
    
18. fig = plt.figure(figsize=(15, 10), constrained_layout=True)
    
19. gs = GridSpec(10, 1, figure=fig)
    
20. ax = fig.add_subplot(gs[:-1])
    
21. ax.barbs(t_mesh, z_mesh, u.T, v.T, ((u**2+v**2)**0.5).T, length=7, barb_increments=barb_increments,
    
22.             norm=norm, cmap=cmap)
    
23. ax.set_xlabel('时间（mm-dd: hh）', font=font, fontsize=15)
    
24. ax.set_ylabel('高度（m）', font=font, fontsize=15)
    
25. ax.set_yticks(u.columns)
    
26. ax.set_title(xlsx_path[:-5], font='simsun', fontsize=20)
    
27. ax = fig.add_subplot(gs[-1])
    
28. ax.barbs(legend, np.zeros_like(legend), ((legend**2)**0.5), length=7, barb_increments=barb_increments,
    
29.             norm=norm, cmap=cmap)
    
30. for x, lg in enumerate(legend):
    
31.     ax.text(x+0.1, 0, f'{lg}', verticalalignment='center')
    
32. ax.set_xlim(-2, 7)
    
33. ax.text(-1.5, 0, '图例（m/s）', font=font, verticalalignment='center', fontsize=15)
    
34. ax.axis('off')

横坐标设为时间，纵坐标为level就可以了吧？
