Geo Line Aggregation Usageedit
The geo_line aggregation aggregates all geo_point values within a bucket into a LineString ordered by the chosen sort field.
Be sure to read the Elasticsearch documentation on Geo-Line Aggregation.
Fluent DSL exampleedit
a => a
.GeoLine("line", d => d
.Point(p => p.LocationPoint)
.Sort(p => p.StartedOn)
.IncludeSort()
.Size(25))
Object Initializer syntax exampleedit
new GeoLineAggregation("line", Field<Project>(f => f.LocationPoint), Field<Project>(f => f.StartedOn))
{
IncludeSort = true,
Size = 25
}
Example json output.
