Hello,

I've an application with two modules - frontend & backend.

Both are getting scanned for defects multiple times a day.

We're collecting these results and pushing them over Elasticsearch, so we can see the defects trend.

I want to project this trend in Kibana visualization in daily basis, possibly in a line graph.

Thing is I must not take data of every scan as each module is getting scanned more than once in a day and taking sum of scan1 and scan2 will give wrong result.

So, I want to take top hit of each module, then take sum of both modules and show in a single line graph.

In other words, "Sum of top hits of both modules"

I'm very new in Kibana and not able to fully understand [top hits aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-top-hits-aggregation.html).

So kindly suggest how can I make this visualization?

Thanks

In Visualize, start by configuring a `Buckets` `Split series` to split your data by type.

Then configure `Metric` to use a top hit aggregation. Other aggregations will calculate the metric value from all documents in a bucket. The top hits aggregation will only calculate the metric value from the first X documents in each bucket. In the example provided, the top hit will be the most recent document for each term `machine.os.keyword` ordered by field `timestamp`
