Tables are dynamic such that if there are only 5 values for a "Top 25" resource then only 5 rows of data will be displayed. Radial gauges are configured individually and are hard coded for a particular metric for a specific node or application. So while what you are asking for is possible using the Custom Object Resource, each radial gauge would need to be individually configured to reflect a specific metric. The number of metrics displayed via these radial gauges would be fixed and not based on a "TopXX" bases. As such these radial gauges would also not be sorted or prioritized on the page based on their statistic measurement. Perhaps a better way to display this information would be through the use of a TopXX custom chart resource?
