Groups shown in grafana(Duration or cumulative response time of individual requests?)

I have followed the docs for integrating grafana- influxdb- gatling for real time monitoring

In the groups i saw someone suggested to use this template to show the groups in grafana








And i was able to see the groups in grafana by this query

SELECT “percentiles95” FROM “gatling” WHERE “request” <> ‘allRequests’ AND $timeFilter GROUP BY “group”

This is the output i got

Ii need the clarification whether these points which are showing in a weird manner are actually the duration of that particular group at that time . There was one group request sent and why there are multiple points ?. Is the query wrong ? There should be one point after the completion of the group request. (which is the duration) or is it supposed to be like this . can anyone please answer ?
