I don't use 14all, but rrdtool has a lazy option for generating graphs (
[-z|--lazy] ).
If 14all is graphing to stdout, that will not help you.
If 14all is graphing to disk and it is serving you (in the html img tag)
a link to that file,
than it may help you. 

You could then setup an entry in your crontab to fetch the pages every 5
That way you are always sure to get the freshest image and to have it
waiting on disk.

Use wget, lynx or any tool you like to fetch the pages.
