Hi All
I am having a bit of trouble with the my panel plot. I am trying to display precip climatology for the region (lat:10N,40S lon: 10W,70E) and overlaid with 2 regression lines of max precip for the obs and model. Attached is the output and I am not sure why it is cutting off the domain like that. Below is my code, please let me know if you can see where I am doing something wrong.
Many thanks!
Kind Regards
Melissa
