Graph + Single Stat visualization

This page documents an earlier version of InfluxDB. InfluxDB v2.7 is the latest stable version. View this page in the v2.7 documentation.

The Graph + Single Stat view displays the specified time series in a line graph and overlays the single most recent value as a large numeric value.

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

Graph + Single Stat behavior

The Graph visualization color codes each table (or series) in the queried data set. When multiple series are present, it automatically assigns colors based on the selected Line Colors option.

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 Single Stat results, the query should return a single table.

Graph + Single Stat Controls

To view Graph + Single Stat controls, click Customize next to the visualization dropdown.

Graph + Single Stat examples

The primary use case for the Graph + Single Stat visualization is to show the current or latest value as well as historical values.

Show current value and historical values

The following example shows the current percentage of memory used as well as memory usage over time:

Query memory usage percentage

from(bucket: "example-bucket")
    |> range(start: v.timeRangeStart, stop: v.timeRangeStop)
    |> filter(fn: (r) => r._measurement == "mem" and r._field == "used_percent")
