The screenshot on the left shows a large view of some of the statistics that can be shown in XRG. Each graph can be enabled or disabled depending on your preferences. From top to bottom are the CPU graph, Memory graph, Temperature graph, Network graph, and Disk graph. These are all the graphs that monitor an aspect of the computer you are running it on, except for the Battery graph on Powerbook/iBooks.

The top screenshot on the right shows the two non-computer based graphs: the weather and stock graphs.

The middle screenshot on the right is showing the temperature graph on a Dual 2.5Ghz G5 system. The graph is expanded to have room for all of the various sensors that can be monitored.

Finally, the bottom-right screenshot shows how 4 primary monitors (CPU, Memory, Network, and Disk) can be displayed in a very small window. The window could be made slightly smaller even, but beyond this size the data isn't really able to be displayed as clearly because of the amount of text that must fit in the window.
