Please explain the logic of your table. In particular, the meaning of "Benefits" (1 thru 4) isn't clear.

Perhaps, in addition to explaining your idea, please tell me where my approach is wrong:-

I think that for any given year a conservative approach should give a result different from an aggressive one. Therefore you need a table with years, say, on the X axis and Con/Real/Agg on the Y axis. If you would have such a table you could place the 20% benefit in the first year in relation to the Condition (risk-taking preference).

In short, if you wish to let your graphic display the effect of both Condition and Year it would be your table's duty to establish a relationshop between the two. This isn't the case, and therefore you have difficulty. To resolve the problem establish the relationship.
