I'm still not sure I get it. What about a Scatter chart with the points connected? Would that be reasonable? With this you'd specify a max X value of say 365 to represent a year, and then plot the values based on that, ie: 67,57|234,80|57,89 ad infinitum. Then just connect the points. If there's a pattern, it would become apparent. -- Richard Heyes HTML5 graphing: RGraph (www.rgraph.net - updated 6th June) PHP mail: RMail (www.phpguru.org/rmail) PHP datagrid: RGrid (www.phpguru.org/rgrid) PHP Template: RTemplate (www.phpguru.org/rtemplate) PHP SMTP: http://www.phpguru.org/smtp
