[Mesa-users] [EXT] Pgplot - how to produce pdf plots?

[Mathieu Renzo]

This depends on what plot you are trying to save. For each of them there 
is a *_file_dir entry in the inlist_pgstar that you can customize. This 
is the sub-directory of the work directory where the pgstar files will 
be saved.
For example, for an HR diagram that would be  `HR_file_dir`, which is by 
default set to `png`, so with the changes suggested above by Rich I get 
the files in hr_000005.eps in my work directory/png (but you may change 
this to any other subdirectory you want).

So unless you have changed the *_file_dir explicitly, your eps will be 
inside the default folder which is probably called `png`.


To save only the last one you could catch the stopping criterion of your 
model in your run_star_extras.f90 and call the function defined in 
star_lib called pgstar_write_plot_to_file (but I have not tested this).

I hope this helps!
