There is no prob getting the graphs working, depends on what you want to show.
Here on my testpage the 1st gauge graph is working:
http://www.hetweerinruinen.nl/flash/gauge3/gauges-ssT-nl.htm
i used wxgraphs(jpgraph) to create the graph, in gauges.js set the var imgPathURL to your wxgraphs dir.
And in stead of ddimgtooltip.min.js use ddimgtooltip.js. Don’t forget to set this in your page also!
Edit ddimgtooltip.js, on line 24 etc you can change the temp.png in for example temp_24hr.php.
And then you have your graph made live on the fly.
