I'm doing an astrophysics thesis with a lot of programming in Python. I'm currently using gnuplot for my plots, but I wonder if this is actually looking quite professional. Are there other options which look better and are still easy to use?
Here an example of a figure in my thesis:
The vertical line I got with the following command:
set arrow from 4861.3,-1200 to 4861.3,2000 nohead lc 2
I know it reaches out of the figure, but I use this command for all of my script and I know only at the end what the upper and lower boundary of the y-axis will be. Every peak is different.
