I love charts and graphs. The visual representation of data really lets you get a picture of what’s going on. I have recently updated a bunch of our data collection, logging and now the pretty pictures part. We have been collecting this data since about May of last year. I have 2 versions of the graphs, the last 15 hours (in 5 minute increments) and also the daily averages going back to last May. Both of these allow you to zoom and change the rolling averages. To zoom, drag select a region from left to right. Double-click to reset. The little box in the lower left with a number in it is the rolling average, defaulting to 1. On the yearly data if you enter a 7 and hit enter you will see the data re-shaped on a 7 day rolling average. In the more live trend data entering a 12 would let you see the 12 x 5 minute or hourly rolling average. There’s also the status page of what’s happening now (nearly).
