Paul, Great Idea...would need quite a bit of data from the server, a polar plot would look good. I may use that idea with respect to a strip chart recorder as a first pass. It would be real easy to generate the chart with no scale or time with rrdtools as its a standard rrd option I think, then flip it 90 degrees within the client and then create the data display above the chart. I'll take a look at the concept over the next couple of weekends of the strip chart recorder and may have to make the circular chart version when my skills have improved or gain help from the raphael list.
