Dimension using set analysis or calculated field consisting STRING field with respect to DATE

[wiz_nerd]

I am Trying to create a dimension using these fields. But i just want data for latest "n" dates.

I want to used the Table  field name on x axis with respect to last three dates per field. 

and I could not conclude as I am new but I have come across how to parse date field in rfc format.
