Add an ability to render per-request chart with detailed information about each request

[MurzNN]

Now, in charts we can see only the aggregated data from all requests per a timespan (eg avg, max, min, p95).

But pretty often we want to see the detailed info per each made request, and seems this is not available yet in xk6? Related question: #90

So, will be good to add the ability to render per-request charts. What do you think about this idea?

I completely agree with @MurzNN on this. When we are running load tests and comparing to previous load test runs, there might be 1 or 2 specific requests that "are not performing well today on this release" - but the majority of the 100's of other requests are performing just fine.

As an operator of a continuous performance pipeline automation with performance-based quality gates,
I need to block a release based on any % variance increase in response time for a specific request(s),
So that we can automatically open a defect/investigation ticket for the root-cause of the performance issue.

We can get this information from other tools producing output, so it must be available somewhere?

This feature is partially completed, but not yet available. The metrics will not be available per URL, but per tag, and the URL can also be a tag.
Currently, higher-priority feature developments precede this feature, but it will also be ready in time.

Do you have news about this functionality of fine-tune graphs by tags ?
