Temperatures plugin

Hi.

First of all I have to say that munin is great, I have been using it for
a good 6 months now and never experienced any troubles.
Now, here comes the (probably dumb) question: I recently added the
temperatures plugin
( http://muninexchange.projects.linpro.no/?search&cid=23&pid=37&phid=36 ) but I 
couldn't get it to plot the temperatures.
I configured the plugin by setting "env.wcode LIPE EBBR LIVT" in
munin-node.conf but nothing on the graph.
What is odd is that the graph displays the correct locations' name, but
no temperature data is plotted or displayed.

I noticed that the plugin source code contains this "if" condition:

> if (defined($ENV{wcode})) {
>     @wcode = split(' ', $ENV{wcode});
> } else {
>     @wcode = ("ENGM", "ENBR", "ENVA", "ENTC");
> }

I replaced the codes with the ones I needed and executed the plugin
from a bash shell.This was the output:

> amoeba:/etc/munin/plugins# ./temperatures
> LIPE.value 11
> EBBR.value 11
> LIVT.value 16

So it seems that the values are correctly retrieved from 
http://weather.noaa.gov/ .
But still, nothing on the graph.
What did I miss?
