解决了，大家不用看了

pres@gsnPanelLabelBar = True 这个改为False试试
有问题多去官网看看
gsn_panel / gsnPanelLabelBar - Fixed a bug where if you are running a script that calls gsn_panel to panel XY plots and setting gsnPanelLabelBar to True, then you would get a fatal error:
fatal:Variable (mono_fill_scl) is undefined
fatal:["Execute.c":8640]:Execute: Error occurred at or near line 6100 \
