I have logs containing signal strength that I want to plot. Only changes in signal strength are logged.
I would like to make a graph in timelion (or a normal line graph) that takes each value as is and plots them in a timeseries so I end up with a line showing each individual value.
However if I do something like
.es(EbNo:*)I end up with the count, which I don't want.
$ebno_query='EbNo:*', .es($ebno_query,metric='avg:EbNo').fit(none) works better but I don't want averages.
I simply want to connect the dots between different values at different times (there will be only one value per timestamp). How can I do this?
Separate questions 1: Is it also possible to define max. and min. values for one of the axis?
Separate questions 2: Is it possible to continue drawing a line from the last known value? E.g. the last log entry was EbNo 5 at 12:00 but my dashboard is showing from 11:00 until 14:00. Can the line from 12:00 until 14:00 show EbNo 5?
