Line chart

Applies to: ✅ Microsoft FabricAzure Data ExplorerAzure MonitorMicrosoft Sentinel

The line chart visual is the most basic type of chart. The first column of the query should be numeric and is used as the x-axis. Other numeric columns are the y-axes. Line charts track changes over short and long periods of time. When smaller changes exist, line graphs are more useful than bar graphs.

Note

This visualization can only be used in the context of the render operator.
