Just wondering why we put an iFrame tag around the image. Should it no be possible to reload the image without an iFrame? Very good question. I think this is because we needed a way to change only the image and JS wasn’t an option back then. The tag allowed to specify a target which changed the content of the iframe. I would absolutely prefer to get rid of it and just use one or multiple img tags.

Would it not be better to remove the iFrame and make the links for hour/day/month/year firing some JavaScripts which reloads/changes the graphs? And then when we click hour start this script to reload the graphs periodically? Agreed. I very much like the idea and I think this is an opportunity to clean up a little bit more. I will let you two sort out the technical things and how often is best to reload :) > Thanks for the nice patch. It is easy to review :-) > > Greetings Jonatan -Michael
