  1. Create Plots using rrdtool

    Next step for my humidity logger is to get nice plots. Here rrdtool seems to be the tool of choice.

    First create a few rrd-files. For example:

    rrdtool create humidity.rrd --step 30 \
      DS:humidity:GAUGE:120:0:100 \
      RRA:AVERAGE:0.5:1:1200 \
      RRA:MIN:0.5:12 ...

    • avr packages on Ubuntu ...
