Analysis Graph is taking too long to load

[noppanit]

Hi,

We're seeing the issue with Analysis Graph is taking too long to load. I found out that the code is doing mysql query for each day and in our case it times out from the server.

Not sure if there's a PR that's fixing this already? We did a fix by doing one query and group by date and do the cumulative in memory instead. I'm happy to do a PR but just want to make sure that's nothing like this already.
