Running Total in Graph

[#1]

Hello,

I Want to realize a Graph (line) in wich for each date i show the YTD value. A normal sum with Full Accumulations doesn't work when the users selects a part of the year to see in detail . This was the definition but ... doesn't work.

AGGR(SUM({<DAT_YEAR=,DAT_MONTH=,DAT_DATE={">=$(=YearStart(DAT_DATE)) <=$(DAT_DATE)"}>} DSH_TICKETS))

Could anyone help me out ?
