[Maps] Simple arithmetic for Metrics in Map Visualizations

[anottrott]

Perform simple arithmetic on fields within a Metric on a Maps Visualization?

For example, I want to create a region map where the regions are colored by the ratio of two Fields. So I have field_1, field_2 and field_3 and I want to roll up the value

SUM(field_1)/SUM(field_2)
or another example
SUM(field_1) + field_3

In another example, I want to create a region map where the regions are colored by the sum of two fields
SUM(field_1) + field_2

An update for anyone interested in this is that this functionality can be achieved using Vega visualizations

Hi,

Similarly, would be useful to be able to map an equivalent of the TSVB Filter Ratio.

As suggested, we're doing it through Vega visualizations at the moment and it's quite powerful.
But there are some issues like (for example) the following :

• [[Vega/EMS] Problems using EMS map World Countries
• [[Kibana/Vega] “inveted” EMS vector maps in Vega](https://discuss.elastic.co/t/kibana-vega-inveted-ems-vector-maps-in-vega/285825)

Having it natively in Kibana Maps Visualization would be much easier.

Use case is we have logs that flag successes and failures and need to check the Success (or Failure) ratio over time.

Thanks.

@Kayak007 8.2 release includes the ability to create EMS region maps in lens. This will allow users to use all of lens formula capabilities while creating a region map. Hope this helps your use case.

Closing this because there is a workaround using Lens.
