I am new at Grafana and i am trying to configure a dashboard with a dynamic time range obtained from two fields of a MySQL table (start and end in unix time format). I tried to use $__timeFilter but i was unable to make it work. I also created two variables ($t_start and $t_end) to play with them but i am unable to update dashboard time range when i change these variables.
Is it possible to do it?
Thanks in advance.
