Rolling median

[Evgeniya]

Hi All!

Please help me to resolve some problem with calculation median.

I have table with two coloms: DateTime,Value.

I need make line chart with rolling median for last 24 hours. 

I use formula:  Median(Aggr(Above(sum(Value),0,1440),DateTime))

But It doesn't  work. I  get result such us if I use sum(Value).

Anybody know how resolve this issue?
