If the Color scheme is set to From thresholds (by value) and Gradient mode is set to Scheme, then the line or bar color changes as they cross the defined thresholds. Grouping by some time expression gives you separate sums - one sum for each separate time expression value. This transformation can help eliminate the need for multiple queries to the same datasource with different WHERE clauses when graphing multiple series.

Use the or logical operator to filter by multiple fields. With upcoming Grafana v5.4.0 you'll be able to say that the alert condition should trigger for some time before actually alerting . This option controls how the graph interpolates the series line. Making statements based on opinion; back them up with references or personal experience. It can render series as lines, points, or bars. when the subsequent value is less than the previous value and nonNegative is Do I need to do something in Influx for this? It is versatile enough to display almost any time-series data. Side-by-Side : Presenting the Data. Bulk update symbol size units from mm to map units in rule-based symbology. Navigate to the panel where you want to add one or more transformations. The values come from a different measurement. This is a method to take data with multiple different values that all apply to the same series not necessarily a time series and collapse them into a smaller subset of data based on one of the columns. Will show an option to specify a DateFormat as input by a string like yyyy-mm-dd or DD MM YYYY hh:mm:ss.
