Line Charts

Line charts are useful for displaying how data changes over time, where the Y axis of a line chart displays the count of an item, and the X axis is a timeline.

To create a line chart, you need to use a query that provides more than one data point in the Aggregates tab, see aggregate operators for details. Then the line is drawn between the data points to show the change.

For example, you'd use the following query to create a Line chart:

error | timeslice 1m | count by _timeslice

which would produce results such as:
