I have a beamer presentation with some pgfplots graphs and want to increase their thickness. I found this answer How to increase the thickness of the graph lines and remove the point?, but I found ultra thick not thick enough and I do not have enough rep. to comment.

My question is: is there a way to increase the thickness of graph lines to obtain lines larger than with the ultra thick option?

Using line width option would do the job.
