Agreed Sinthuja. But what about for a smaller window size (5/10/15 mins)?
The reason why I bought up this issue is, in my case, I use several real time gadgets. And at the startup, they are all empty for that user until the data gets pushed in. As an end user, I would like to see the last status of the real time analytics when I log in.
