想要将亚洲转到图片下面

1. fig = plt.figure(figsize=(12,16))
   
2. proj =ccrs.NorthPolarStereo(central_longitude=0)
   
3. leftlon, rightlon, lowerlat, upperlat = (-180,180,20,90)
   
4. # 生成一个圆形的Path
   
5. theta = np.linspace(0, 2*np.pi, 100)
   
6. center, radius = [0.5, 0.5], 0.5
   
7. verts = np.vstack([np.sin(theta), np.cos(theta)]).T
   
8. circle = mpath.Path(verts * radius + center)
   
9. 
   
10. fig_ax1 = fig.add_axes([0.05,0.5,0.8,0.4],projection =ccrs.NorthPolarStereo())#左下角坐标(x, y)、宽度、高度。
    
11. fig_ax1.gridlines(draw_labels=True,x_inline=False, y_inline=False)
    
12. fig_ax1.set_extent([leftlon, rightlon, lowerlat, upperlat], ccrs.PlateCarree())
    
13. fig_ax1.add_feature(cfeature.COASTLINE.with_scale('110m'))
    
14. fig_ax1.add_feature(cfeature.LAKES, alpha=0.5)
    
15. plt.tick_params(labelsize=20)
    
16. #fig_ax1.set_title('(a) 500hPa in 1983',loc='left',fontsize =20)
    
17. # 将该Path设置为GeoAxes的边界
    
18. fig_ax1.set_boundary(circle, transform=fig_ax1.transAxes)
    
19. cycle_zg3, cycle_lon = add_cyclic_point(zg3, coord=lon)
    
20. cycle_LON, cycle_LAT = np.meshgrid(cycle_lon, lat)
    
21. #c1=fig_ax1.contourf(cycle_LON, cycle_LAT, cycle_zg3, levels=np.arange(-250,251,25),zorder=0 , extend = 'both',transform=ccrs.PlateCarree(),cmap='PiYG_r')
    
22. fig_ax1.set_boundary(circle, transform=fig_ax1.transAxes)
    
23. cycle_la1, cycle_lon = add_cyclic_point(la1, coord=lon)
    
24. cycle_LON, cycle_LAT = np.meshgrid(cycle_lon, lat)

尝试修改central_longitude=0没有用

weibi

fig_ax1 = fig.add_axes([0.05,0.5,0.8,0.4],projection =ccrs.NorthPolarStereo())这儿改

哦哦感谢！！！
