the weblink refers to the current logfile, then it will be stored as a
CURRENT weblink, and it will always display the most recent log (you do
not have to redefine it if the logfile changes due to year/month/date
parameters in its name).

The logs can be converted to a plot either with gnuplot (which must be

In order to look at historic data, you can either convert at the
archive entries to weblink in "plotmode=gnuplot" mode, or use the
"plotmode=gnuplot-scroll" or "plotmode=SVG" modes. In the latter case
you'll get the possibility to zoom or scroll in the plot.<br><br>

The current time scope (day, week, month..) set at the overview
page (containing weblinks) will also be used for graphics you open via
links (current log or archive) - there are no zoom and scroll icons
there.<br><br>
Note: the gnuplot files must have #FileLog entries in order to be
useable with scrolling, as the filtering happens with the FileLog get
function, see the supplied gnuplot files for an example.<br><br>
The order of the #FileLog lines need to match the corresponding
'awk'-(double-)lines!<br><br>
It make sense to build large logfiles for scrolling in them (year
resolution), or smaller ones if you do not want to use the zoom/scroll
feature. The size of the logfiles will be determined by its wildcard
characters (year/month/week/day), look at the FileLog definition.
Don't forget to enable archiving with the archivedir or archivecmd
attributes.<br><br>
