Hi guys,

I'm trying to use Jpgraph-2.1.1 with postgresql-8.1 and php5.1.2 to show some charts from postgresql database.

I have 4 tables in my database and I'm interested in the "val_data" and "val_time" columns from table "valori". They hold temperature values collected at different times.

I want to show a chart of the temperature modifications foar the last 20 days (for example).

Help me asap, please!

Thanks
