The information in this link will get you where you need to be as far as getting two years on the same axis. The question of having it only show for years will need to be done with a calculated field that explicitly says 'IF year then show this' . I wish I could download your work and be more specific, but that is not allowed here.
To show full year and YTD next to each other , you need to duplicate all the data/formula twice, which is not reasonable workload to consider the balance between effort and benefit.
Instead, how about to add YTD in parameter?
(Simplified this one as well)
** Order date filter is used to get max date by context filter and LOD.**
