[rrd-users] y-axis encoding problem

[Kevin Kettinger]

Hello,

i'am trying to plot two temperature sensor values with rrdtool. The 
y-axis should display decimal values (the resolution of the sensor 
reading is 0.1).

When i plot the graph without --y-grid, the values in the y-axis are 
ploted fine. But when i use --y-grid (e.g. --y-grid 0.1:1), the values 
of the y-axis become strange chars (graph in the attachment).

My command:
rrdtool graph \
--alt-y-grid \
--alt-autoscale \
--y-grid 0.1:1 \
-L 20 \
--height 500 \
--start -1hour \
/var/www/temp_hourly.png \
DEF:temp_inside=temp.rrd:temp_inside:AVERAGE:step=60 \
DEF:temp_outside=temp.rrd:temp_outside:AVERAGE:step=60 \
LINE1:temp_inside#00ff00:"temp inside\l" \
LINE1:temp_outside#0000ff:"temp outside\l"

I also get sometimes the warning:
(process:16088): Pango-WARNING **: Invalid UTF-8 string passed to 
pango_layout_set_text()

LANG is en_US.UTF-8 and all scripts are UTF-8 encoded.
The rrdtool version is 1.4.3, os is Linux Debian 6.0.5.
On my system, the problem also exists with the rrdtool version 1.4.7.

Maybe someone got an idea.. thanks.

Best regards,
Kevin
