Mjukare grafer?
Postat: 09 mar 2013, 17:37
Hej,
Har ett litet problem med mina grafer, de blir väldigt taggiga, hur fixar man det?
Se exempel på http://winserv.9c.se
Jag har lagt upp det så här i crontab.
Kör så på scriptet som skapar png filen och hämtar temperaturen.
Min rrd fil.
Och mitt script som skapar png filen (om man kan göra något här?)
