Web graph temperature scaling

Just wondering how the scaling of the web graphs is adjusted?

All my web graphs are going off scale eg
http://www.portunus.net.nz/weather/48hourgraph.gif

all the screen graphs are fine and I’ve looked for any rogue data in case it’s something to do with autoscaling

problem has been happening since may 25, not sure if it was program update introduced or something I have changed? looked everywhere though
Any suggestions most appreciated :slight_smile:
