For automated plotting one can use cron to run a bash script
to do seltection and plotting.

The programs need are gnuplot and seltag.


Cron example:

# Run sens.sh and update plots every minute
# Arguments are sensor ID, number samples and file name
# See sens.se
* * * * * /usr/local/scripts/sens.sh 0007f 5000 main-power.png

Look into the examples directory for sens.sh and gnuplot file
