Is possible to do this?

[Dsky]

i want to write a stylesheet that allow me to register (for a month for example) the min of every day...

like this

1/1 : -1,3°C
2/1 : -4,6°C
3/1 : -5,4°C
4/1 : -6,7°C
5/1 : -4,3°C
6/1 : -1,4°C
7/1 : -0,2°C

You can try this:

$Stats[20080101,Min,outdoor_temperature]
$Stats[20080102,Min,outdoor_temperature]
$Stats[20080103,Min,outdoor_temperature]
....

But you need to know the date 20080101.
The NOAA report generate the list of min...may be you can process the report with a php script.
