I'm trying to create a map visualisation (ideally a heatmap, but shaded circles will do nicely) based on a geo_point field in my index. I've got a small index (300~ documents) that contain a "Location" geo_point field, and other fields such as temperature.
So far, I've been able to create a visualisation of this data by going to
Visualize > Create New Visualisation > Coordinate Map
Then, under Metrics selecting (for example) Average:Temperature, and under Buckets by Geo coordinates geohash aggregation.
The result is several large circles, about seven in total coverage a considerable distance (200m). This is not good, and would instead prefer smaller circles of maybe a few meters in size.
I'm quite new to Elasticsearch and Kibana so I think I might be missing how to set the size of the geo coordinate aggregation Bucket - but I can't find a way how to change it.
- I should also add, if I view my index via the Maps tool (rather than Visualize) I can achieve what I require - small map points from my index, but can't see how I can display my metric; temperature.
Thanks for any help
