Do know why? 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 <a> 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. Those would also make styling easier.
Therefore it is possible to refresh them periodically without reloading or changing the pages. This patch adds a graph reload javascript to the ipfire main theme.

Yes this is brilliant :)
Hi,
This is more of a nice-to-have, an idea I would like to present. As I was working on the QoS graphs, I noticed that all RRD graphs are embedded in an iframe. I wrote a little javascript that periodically reloads these graphs.
Would it not be sufficient to reload only the hourly graph? So all others have a range where I would not assume somebody to monitor them “live“.
The refresh interval is based on the graph's time range, i.e. hourly graphs are refreshed more often. Reloading should stop in case of a network error, but I haven't fully tested this yet.
This patch adds a checkbox to the GUI settings (default: disabled), translations, ... If you just want to try the javascript, you can simply paste it to the html <head> in html/themes/ipfire/include/functions.pl. Be sure to escape the '$' then.
Best regards Leo

Does this actually need configuration or can we not simply enable this for everyone?
What is the downside? If the browser has JS disabled, simply nothing would happen.

Some generic thoughts. 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 :-)
