Please guys look at to this one I have done the whole visulization the issue Im facing here is this table visulization is showing every single update of a device , I jus wanted a single device_id which is latest on com_send_time here we have
24-07-2015 11:54:34 updated .
This is the device which must be there
865733022351852 24-07-2015 11:54:34 updated .
865733022352314 24-07-2015 11:59:18 updated.
so on upto 535 device_id
many devices also give " fail" as response code so if there latest data is failed or" in progress" or "not connected" it should show that.
