I have the database where 3 columns: Mode (smallint), UserId(Int), Datetime (Timestamp).
When some user visit site, script writes in db (1 (online), <user_id>, )
When some user leave site, script writes in db (0 (offline), <user_id>, )
I have 15 users and I want to create graphic for each but I don’t want to create them manually. Can I automate process?
