You are more than welcome!
For the y-line, just add
*************
yline(0, lpattern(dash_dot) style(default) )
*************
to the -eclplot- call. Change the pattern according to your taste (-help
linepatternstyle-)...

Thank you so much Martin, this looks fantastic!
I had never used either parmest or eclplot!
Do you know how I could add a horizontal dotted line at zero?
Best wishes,
