Thanks Kumar for your illustrations! I guess dual axis is an option to add symbols to line chart. Your workaround appears to be in the same vein it would seem. I am still a bit disappointed with the lack of line type options.
So the great thing about Tableau, is that without adding lots and lots of features (i.e. keeping the UI simple [well simple, compared to what can be done!] & consistent) it encourages users to use the existing features to create the things we might need (without adding lots of extra options). The line-weight can be changed using the Size tile (either as slider, or data driven [by putting a measure on the Size tile). For dotted lines, this blog post should help
Hope that helps
