Hey Alex,
from the rrdtool documentation for PRINT
http://oss.oetiker.ch/rrdtool/doc/rrdgraph_graph.en.html#PRINT :
%#.#lf
prints numbers like 12345.6789, with optional field width and precision
I use in my template files : PRINT:<!-- rrd_sensid -->:MAX:"%5.1lf C"
to get my temperatures to display as "25.1 C"
Hope this helps,
Bruce

Subject: [Owfs-developers] Changing Number Format of Y-Axis on
TemploggerdGraphs
Hi Guys,
With temploggerd, can I specify a Y-Axis display mask like XX.X anywhere so
I get temperature labels with 1 decimal place?
When temperatures are not changing much, the graph auto-ranges in and
compresses the range such that the displayed labels have several instances
of each oC value without a single digit after the decimal place. I end up
with Y-Axis labels like:
20,20,20,21,21,21,21,21,22,22,22,22,22,23,23,23,23,23,24,24,24,24,24 (ie 5
labels all saying 21, 22, 23, 24 instead of 21.0, 21.2, 21.4, 21.6, 21.8,
22.0...
Regards
Alex Shepherd
