Dear GrADS users,
I need help in fixing the following problem.
I am trying to create an inter-annual time series for present and future climate. Now, when I run the script it gives me overlapping time series. What is want to obtain is the distinction between present and future precipitation change.
Also, how can I obtain a linear regression within the same graph?Kindly enlighten me.
Please see the script and an image as attached files.
Thank you
With Best Regards,
Mehwish
