-               Plots the temperature and rain (per hour and per day) of a

-               device named ks300) looks like:<br>

-          </li>
-           <li>hum6wind8<br>
-               Plots the humidity and wind values of a

-           <li>text<br>
-               Shows the logfile as it is (plain text). Not gnuplot definition
