TopX widgets are available on the Dashboards page and the Analyze page to display charts showing the "TopX" (as in "Top 10," "Top 20," etc.) results for events or metadata within a specified time range. The number of results depends on the data available and how large you make the widget. TopX widgets are dynamically driven, and the charts they display are updated every 20 seconds.
For more information on the metadata that can be displayed in a TopX widget, see Metadata Fields.
