The RRDtool library does not support gauges; you'll need to write your own code to do this.

I have made available a CGI script that uses the swfgauge utility to generate constantly updated gauges fomr the RRD files generated by MRTG, this might be of use to you - you could potentially use it as a base to generate a more generic utility?

This is the gauge demo
although apparently it has some problems executing on some browsers due to security settings.
