@bad inferno: Using sample html and javascript from the internet and a little rewriting I managed to build my own webpages showing about what you are talking about. Difference is that I did it using iFrames on top of the RRD-graphic using transparency. Use a transparent background (e.g. your scale) and 'write' text on top of it. The needed html-lines for the iFrame are created with echo-statements from a bash-script. This script also takes care of the reload of the data to the frame after an alteration of the min/max-limits. So this takes care of real-time updating. When the limits are crossed a small alarmbell will show on top of the graphic and the text IN the rrd-png will change!! Also an email will be sent with a maximum of one per hour. So I needed no additional tools or packages. The greatest addition (I think) is a transparent night-period showing (again) on top of the RRD-png moving in time. This is done by writing position-parameters to a CSS-file. The limit-setting box uses cgi and a bash-script again rewriting the iFrame with echo-statements so you can include variables for displaying the new or editted temp-settings.
