添加text后出现ValueError，提示图片太大

黄小仙儿

各位，我画图想添加text，没有添加之前图可以出，
ax.text(x=1,y=2,s='ss',fontdict=dict(fontsize=14,color='k',family='Simsun'),transform=ccrs.PlateCarree())
但是添加后只有提示错误：
ValueError: Image size of -558547720x386224160 pixels is too large. It must be less than 2^16 in each direction.我看了很多帖子感觉是ax设置的问题，但是不知道怎么修改。我把我画图的代码贴上来，大家帮忙看一下
