Hi Sebastian This page has some good examples
http://hints.jeb.be/category/rrdtool/ In short I don't think you can mix none strftime variables and strftime variables so in your example GPRINT:tmax:"max %0.2lf":"%H" would need to be (using Perl) GPRINT:tmax:%H:strftime Putting %0.2lf would result in "%0.2lf" being printed literally.
