Hi! I generated the following plot and I am trying two things:

1. Shift the the figure a) towards the center.
2. Trying to enlarge the size of the paper in a way that the borders of the plots look a little bit better.

I haven’t got with the correct command? Do you have some suggestion?

Here’s is my script:

col\_cont=217.6/217.6/217.6  
col\_plb=245.7600/204.8000/204.8000

gmt coast -Rg -JE$centerE/$centerN/$map\_horz/$map\_radi -Dc -A100000 -G$col\_cont -Swhite -W0.3p -Baf  
awk -F’ ’ ‘{print($1,$2)}’ Global\_catalog.txt | gmt psxy -Rg -JE$centerE/$centerN/$map\_horz/$map\_radi -Sc0.08c -Gbrown -W.1p,black

Thanks in advance!!

You need -X and/or -Y.  
These are basic options that you’ll find across many modules, including subplot.  
Please take the time to read the documentation.
