Single Stat visualization

The Single Stat view displays the most recent value of the specified time series as a numerical value.

Select the Single Stat option from the visualization dropdown in the upper left.

Single Stat behavior

The Single Stat visualization displays a single numeric data point. It uses the latest point in the first table (or series) returned by the query.

Queries should return one table

Flux does not guarantee the order in which tables are returned. If a query returns multiple tables (or series), the table order can change between query executions and result in the Single Stat visualization displaying inconsistent data. For consistent results, the Single Stat query should return a single table.
